About

A developer who owns every layer of the product.

I like taking a product from an empty repository to something people use every day.

I started my career on map-based portals for the public sector. Today I work as a Full Stack Developer who builds all three layers end to end: the .NET backend, the web application, and the mobile app. From large-scale public platforms serving applicants worldwide to enterprise systems configured separately for each customer, most of what I have built is in active use today.

Lately my focus is on integrating AI into products: RAG assistants grounded in company documents, prompt-injection safeguards, and model evaluation pipelines, on both cloud-hosted models and self-hosted Ollama. I set up my own CI/CD and Docker-based deployments, document architecture decisions as ADRs, and care about writing maintainable, well-documented code.
