Our system is a full‑stack web application composed of a React frontend, a FastAPI backend,

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,

[Reflect on the key technical and collaboration skills learned during this project]
### 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.
[Describe the main challenges and how you overcame them]
### 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.
[What would you do differently? What worked well that you'd keep?]
### Individual Growth
#### [Team Member 1 Name]
#### [Lukas]
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.
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.
[Personal reflection on growth, challenges, and learning]
