-## Table of Contents
-
-- [Table of Contents](#table-of-contents)
-- [1. Design Document (design.md)](#1-design-document-designmd)
-
-The design document is the first deliverable for your project.
-We separated this out as a separate deliverable, with its own deadline, to ensure that you have a clear plan before you start coding.
-This part only needs a cursory review by the teaching staff to ensure it is sufficiently comprehensive, while still realistic.
-The teaching staff will assign you to a project mentor who will provide guidance and support throughout the development process.
-
-## 1. Design Document (design.md)
-
-You are required to prepare a design document for your application.
-The design doc should be brief, well-organized and easy to understand.
-The design doc should be prepared in markdown format and named `design.md` and submitted in the project group's repository.
-Remember that you can use [mermaid diagrams](https://github.com/mermaid-js/mermaid#readme) in markdown files.
-
-The design doc **should include** the following sections:
-
-- **Overview**: A brief description of the application and its purpose.
-- **Architecture**: The high-level architecture of the application, including components, interactions, and data flow.
-- **Technologies**: The cloud computing technologies or services used in the application.
-- **Deployment**: The deployment strategy for the application, including any infrastructure requirements.
-
-The design document should be updated throughout the development process and reflect the final implementation of your project.
-
-Optional sections may include:
-
-- Security: The security measures implemented in the application to protect data and resources.
-- Scalability: The scalability considerations for the application, including load balancing and auto-scaling.
-- Monitoring: The monitoring and logging strategy for the application to track performance and detect issues.
-- Disaster Recovery: The disaster recovery plan for the application to ensure business continuity in case of failures.
-- Cost Analysis: The cost analysis of running the application on the cloud, including pricing models and cost-saving strategies.
-- References: Any external sources or references used in the design document.
+# Personal Finance Tracker
+## Folder Structure
+- meetings: Contains note from meetings 
+- scr: Source code for the project

-# React + TypeScript + Vite
-
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## React Compiler
-
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
-
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
-
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```

 **Brief Description**:
-Our application is a finance tracker, so a person can easily track his cash flow
-through multiple bank accounts. Person can label transactions with custom categories
-and later filter by them.
+Our application allows users to easily track their cash flow
+through multiple bank accounts. Users can label their transactions with custom categories that can be later used for
+filtering and visualization. New transactions are automatically fetched in the background.
 
 ## Architecture Overview
-Our system is a full‑stack web application composed of a React frontend, a FastAPI backend, a PostgreSQL database, and asynchronous background workers powered by Celery with RabbitMQ. Redis is available for caching/kv and may be used by Celery as a result backend. The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories, and transactions. A thin controller layer (FastAPI routers) lives under app/api. Infrastructure for Kubernetes is provided via OpenTofu (Terraform‑compatible) modules and the application is packaged via a Helm chart.
+
+Our system is a full‑stack web application composed of a React frontend, a FastAPI backend,
+a asynchronousMariaDB database with Maxscale, and background workers powered by Celery with RabbitMQ.
+The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories,
+transactions, exchange rates and bank APIs. Infrastructure for Kubernetes is managed via Terraform/OpenTofu and
+the application is packaged via a Helm chart. This all is deployed on private TalosOS cluster running on Proxmox VE with
+CI/CD and with public access over Cloudflare tunnels. Static files for frontend are served via Cloudflare pages.
+Other services deployed in the cluster includes Longhorn for persistent storage, Prometheus with Grafana for monitoring.
 
 ### High-Level Architecture

-flowchart LR
-    proc_queue[Message Queue] --> proc_queue_worker[Worker Service]
-    proc_queue_worker --> ext_mail[(Email Service)]
-    proc_cron[Task planner] --> proc_queue
-    proc_queue_worker --> ext_bank[(Bank API)]
-    proc_queue_worker --> db
-    client[Client/Frontend] <--> svc[Backend API]
+flowchart TB
+    n3(("User")) <--> client["Frontend"]
+    proc_queue["Message Queue"] --> proc_queue_worker["Worker Service"]
+    proc_queue_worker -- SMTP --> ext_mail[("Email Service")]
+    proc_queue_worker <-- HTTP request/response --> ext_bank[("Bank API")]
+    proc_queue_worker <--> db[("Database")]
+    proc_cron["Cron"] <-- HTTP request/response --> svc["Backend API"]
     svc --> proc_queue
-    svc <--> db[(Database)]
+    n2["Cloudflare tunnel"] <-- HTTP request/response --> svc
+    svc <--> db
+    svc <-- HTTP request/response --> api[("UniRate API")]
+    client <-- HTTP request/response --> n2
 ```
 
 The workflow works in the following way:
-- Client connects to the frontend. After login, frontend automatically fetches the stored transactions from 
-the database via the backend API
-- When the client opts for fetching new transactions via the Bank API, the backend delegates the task 
-to a background worker service via the Message queue.
+
+- Client connects to the frontend. After login, frontend automatically fetches the stored transactions from
+  the database via the backend API and currency rates from UniRate API.
+- When the client opts for fetching new transactions via the Bank API, cron will trigger periodic fetching
+  using background worker.
 - After successful load, these transactions are stored to the database and displayed to the client
-- There is also a Task planner, that executes periodic tasks, like fetching new transactions automatically from the Bank API

+
+### Features
+
+- The stored transactions are encrypted in the DB for security reasons.
+- For every pull request the full APP is deployed on a separate URL and the tests are run by github CI/CD
+- On every push to main, the production app is automatically updated
+- UI is responsive for mobile devices
+- Slow operations (emails, transactions fetching) are handled
+  in the background by Celery workers.
+- App is monitored using prometheus metrics endpoint and metrics are shown in Grafana dashboard.
 
 ### Components
 
-- Frontend (frontend/): React + TypeScript app built with Vite. Talks to the backend via REST, handles login/registration, shows latest transactions, filtering, and allows adding transactions.
-- Backend API (backend/app): FastAPI app with routers under app/api for auth, categories, and transactions. Uses FastAPI Users for auth (JWT + OAuth), SQLAlchemy ORM, and Pydantic v2 schemas.
-- Worker service (backend/app/workers): Celery worker handling asynchronous tasks (e.g., sending verification emails, future background processing).
-- Database (PostgreSQL): Persists users, categories, transactions; schema managed by Alembic migrations.
-- Message Queue (RabbitMQ): Transports background jobs from the API to the worker.
-- Cache/Result Store (Redis): Available for caching or Celery result backend.
-- Infrastructure as Code (tofu/): OpenTofu modules provisioning cluster services (RabbitMQ, Redis, Argo CD, cert-manager, Cloudflare tunnel, etc.).

 ## Build Instructions
+
 ### Backend
+
+App is separated into backend and frontend so it also needs to be built separately. Backend is build into docker image
+and frontend is deployed as static files.
+
 ```bash
-# run in project7/backend
-docker buildx build --platform linux/amd64,linux/arm64 -t your_container_registry/your_name --push .
+cd 7project/src/backend
+# Dont forget to set correct image tag with your registry and name
+# For example lukastrkan/cc-app-demo or gitea.ltrk.dev/lukas/cc-app-demo
+docker buildx build --platform linux/amd64,linux/arm64 -t CHANGE_ME --push .
 ```
+
 ### Frontend
+
 ```bash
-# run in project7/frontend
+cd project7/src/frontend
 npm ci
 npm run build
 ```
 
 ## Deployment Instructions
-### Setup Cluster
-Deployment should work on any Kubernetes cluster. However, we are using 4 TalosOS virtual machines (1 control plane, 3 workers) 
-running on top of Proxmox VE. 
 
-1) Create 4 VMs with TalosOS
+Deployment is tested on TalosOS cluster with 1 control plane and 4 workers, cluster needs to be setup and configured
+manually. Terraform/OpenTofu is then used to deploy base services to the cluster. App itself is deployed automatically
+via GitHub actions and Helm chart. Frontend files are deployed to Cloudflare pages.
+
+### Setup Cluster
+
+Deployment should work on any Kubernetes cluster. However, we are using 5 TalosOS virtual machines (1 control plane, 4
+workers)
+running on top of Proxmox VE.
+
+1) Create at least 4 VMs with TalosOS (4 cores, 8 GB RAM, 200 GB disk)
 2) Install talosctl for your OS: https://docs.siderolabs.com/talos/v1.10/getting-started/talosctl
 3) Generate Talos config
-```bash
-# TODO: add commands
-```
-4) Edit the generated worker.yaml
-- add google container registry mirror
-- add modules from config generator 
-- add extramounts for persistent storage
-- add kernel modules
+4) Navigate to tofu directory
 
-5) Apply the config to the VMs
 ```bash
-#TODO: add config apply commands
+cd 7project/src/tofu
+````
+
+5) Set IP addresses in environment variables
+
+```bash
+CONTROL_PLANE_IP=<control-plane-ip>
+WORKER1_IP=<worker1-ip>
+WORKER2_IP=<worker2-ip>
+WORKER3_IP=<worker3-ip>
+WORKER4_IP=<worker4-ip>
+....
 ```
 
-6) Verify the cluster is up
+6) Create config files
+
 ```bash
+# change my-cluster to your desired cluster name
+talosctl gen config my-cluster https://$CONTROL_PLANE_IP:6443
 ```
 
-7) Export kubeconfig
-```bash
-# TODO: add export command
+7) Edit the generated configs
+
+Apply the following changes to `worker.yaml`:
+
+1) Add mounts for persistent storage to `machine.kubelet.extraMounts` section:
+
+```yaml
+extraMounts:
+  - destination: /var/lib/longhorn
+    type: bindind.
+    source: /var/lib/longhorn
+    options:
+      - bind
+      - rshared
+      - rw
 ```
 
+2) Change `machine.install.image` to image with extra modules:
+
+```yaml
+image: factory.talos.dev/metal-installer/88d1f7a5c4f1d3aba7df787c448c1d3d008ed29cfb34af53fa0df4336a56040b:v1.11.1
+```
+
+or you can use latest image generated at https://factory.talos.dev with following options:
+
+- Bare-metal machine
+- your Talos os version
+- amd64 architecture
+- siderolabs/iscsi-tools
+- siderolabs/util-linux-tools
+- (Optionally) siderolabs/qemu-guest-agent
+
+Then copy "Initial Installation" value and paste it to the image field.
+
+3) Add docker registry mirror to `machine.registries.mirrors` section:
+
+```yaml
+registries:
+  mirrors:
+    docker.io:
+      endpoints:
+        - https://mirror.gcr.io
+        - https://registry-1.docker.io
+```
+
+8) Apply configs to the VMs
+
+```bash
+talosctl apply-config --insecure --nodes $CONTROL_PLANE_IP --file controlplane.yaml
+talosctl apply-config --insecure --nodes $WORKER1_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER2_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER3_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER4_IP --file worker.yaml
+```
+
+9) Boostrap the cluster and retrieve kubeconfig
+
+```bash
+export TALOSCONFIG=$(pwd)/talosconfig
+talosctl config endpoint https://$CONTROL_PLANE_IP:6443
+talosctl config node $CONTROL_PLANE_IP
+
+talosctl bootstrap
+
+talosctl kubeconfig .
+```
+
+You can now use k8s client like https://headlamp.dev/ with the generated kubeconfig file.
+
+### Install base services to the cluster
+
+1) Copy and edit variables
 
-### Install
-1) Install base services to cluster

+- `cloudflare_domain` - your domain name managed in Cloudflare
+
+2) Deploy without Cloudflare module first
+
+```bash
 tofu init
 tofu apply -exclude modules.cloudflare
-tofu apply  
 ```
 
-2) Deploy the app using Helm
-```bash
-# Set the namespace
-kubectl create namespace myapp || true
-
-# Install/upgrade the chart with required values
-helm upgrade --install myapp charts/myapp-chart \
-  -n myapp \
-  -f charts/myapp-chart/values.yaml \
-  --set image.backend.repository=myorg/myapp-backend \
-  --set image.backend.tag=latest \
-  --set env.BACKEND_URL="https://myapp.example.com" \
-  --set env.FRONTEND_URL="https://myapp.example.com" \
-  --set env.SECRET="CHANGE_ME_SECRET"
-```
-Adjust values to your registry and domain. The chart’s NOTES.txt includes additional examples.
-
-3) Expose and access
-- If using Cloudflare Tunnel or an ingress, configure DNS accordingly (see tofu/modules/cloudflare and deployment/tunnel.yaml).
-- For quick testing without ingress:
-```bash
-kubectl -n myapp port-forward deploy/myapp-backend 8000:8000
-kubectl -n myapp port-forward deploy/myapp-frontend 5173:80
-```
-
-### Verification
+3) Deploy rest of the modules
 
 ```bash

+- We learned how to use Copilot for PR reviews.
+- We learned how to troubleshoot issues with our project in different areas.
+
+#### Collaboration
+
+- Weekly meetings with the TA were great for syncing up on progress, discussing issues, planning future work.
+- Using GitHub issues and pull requests was very helpful for keeping track of progress.
 
 ### Challenges Faced
 
-[Describe the main challenges and how you overcame them]
+#### Slow cluster performance
+
+This was caused by single SATA SSD disk running all VMs. This was solved by adding second NVMe disk just for Talos VMs.
+
+#### Stucked IaC deployment
+
+If the deployed module (helm chart for example) was not configured properly, it would get stuck and timeout resulting in
+namespace that cannot be deleted.
+This was solved by using snapshots in Proxmox and restoring if this happened.
+
+#### Not enough time to implement all features
+
+Since this course is worth only 5 credits, we often had to prioritize other courses we were attending over this project.
+In the end, we were able to implement all necessary features.
 
 ### If We Did This Again
 
+#### Different framework
+
+FastAPI lacks usable build in support for database migrations and implementing Alembic was a bit tricky.
+Tricky was also integrating FastAPI auth system with React frontend, since there is no official project template.
+Using .NET (which we considered initially) would probably solve these issues.
+
+#### Private container registry
+
+Using private container registry would allow us to include environment variables directly in the image during build.
+This would simplify deployment and CI/CD setup.
+
+#### Start sooner
+
+The weekly meetings helped us to start planning the project earlier and avoid spending too much time on details,
+but we could have started earlier if we had more time.
+
 [What would you do differently? What worked well that you'd keep?]
 
 ### Individual Growth
 
-#### [Team Member 1 Name]
+#### [Lukas]
 
-[Personal reflection on growth, challenges, and learning]
+This course finally forced me to learn kubernetes (been on by TODO list for at least 3 years).
+I had some prior experience with terraform/opentofu from work but this improved by understanding of it.
 
-#### [Team Member 2 Name]
+The biggest challenge for me was time tracking since I am used to tracking to projects, not to tasks.
+(I am bad even at that :) ).
+
+It was also interesting experience to be the one responsible for the initial project structure/design/setup
+used not only by myself.
+
+#### [Dejan]
+
+Since I do not have a job and I am more theoretically oriented student (I am more into math, algorithms, cryptography),
+this project was probably the most complex one I have ever worked on.
+For me, it was a great experience to work on an actually deployed fullstack app and not only local development, that I
+was used to from the past.
+
+It was also a great experience to collaborate with Lukas who has prior experience with app deployment and
+infrastructure.
+Thanks to this, I learned a lot new technologies and how to work in a team (First time reviewing PRs).
+
+It was challenging to wrap my head around the project structure and how everything was connected (And I still think I
+have some gaps in my knowledge).
+But I think that if I decide to create my own demo project in the future, I will definitely be able to work on it much
+more efficiently.
