Summary

Senior full stack developer with 15+ years of experience. I like problems that involve APIs, automation or something clever with AI — and I like turning them into clean, scalable code.

Currently: generative AI (LLMs, RAG, agents), scalable backend architecture, cloud-native applications, clean code and test-driven development. Plus mentoring, knowledge sharing and community building.
