Welcome to my blog. I'm Alex — a full stack / backend developer and M.Sc. Computer Science candidate. I spend most of my time building production systems in Python, FastAPI, Flask, and Odoo, with React on the frontend.
I'm starting this space to write about the things I actually work on day to day:
- Backend engineering — API design, data workflows, and automation with Python.
- Legacy migration — moving older Flask/Bootstrap apps into modern React architectures without breaking what already works.
- AI-assisted retrieval — practical RAG and hybrid search, the kind that solves real lookup problems rather than demos.
Why write at all?
Writing forces me to understand a thing well enough to explain it. If I can't explain how a hybrid search pipeline ranks results, I probably don't understand it as well as I think I do.
So expect posts that are part notebook, part tutorial — the explanation I wish I'd had when I first hit the problem.
What's next
I'm currently working through a hybrid-search RAG pipeline for medical code retrieval. A future post will break down how semantic and keyword retrieval get combined, and why naive vector search alone falls short.
Thanks for reading. More soon.
