Over mij
I’m a Senior Backend & AI Engineer specializing in FastAPI, AWS, and production-grade LLM systems.
I build scalable APIs, AI agents, RAG pipelines, and automation tools using Python, LangChain, and vector databases—with a strong focus on reliability, performance, and security.
Engineering-first approach:
Clean architecture, cloud-native deployment, clear documentation, and maintainable code. If you’re building AI-powered infrastructure, I’ll help you ship it the right way—from MVP to production.
