 ## Architecture Overview
 
 Our system is a full‑stack web application composed of a React frontend, a FastAPI backend,
-a MariaDB database with Maxscale, 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,
-transactions, exchange rates and bank APIs. A thin controller layer (FastAPI routers) lives under app/api.
-Infrastructure for Kubernetes is provided via OpenTofu (Terraform‑compatible) modules and

+The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories,

+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.

 ### Challenges Faced
+
 #### 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
 
-[Describe the main challenges and how you overcame them]
+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.
 
 ### 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.
