Summary
Full-Stack Engineer focusing on Hybrid Architecture. I combine robust backends (NestJS, Python) with low-
code orchestration tools (n8n) to deliver business automation 5x faster.
Core strengths: Building autonomous AI Agents, Document-based RAG pipelines, and scalable microservices.
I don't just write code—I engineer production-ready systems using Docker, AWS, and Clean Architecture
principles.
