Freelancer profile translated to English.

Description

Backend .NET developer with ~4 years of experience, specialized in integrating AI (LLMs, RAG, agents) into real-world applications.

I build robust, production-ready APIs — not just prototypes that work locally. Authentication, caching, concurrency, integration testing: I'll make sure your backend holds up.

If you need to incorporate AI into your product sensibly (without over-engineering) and with a solid backend foundation, I can help.
