## About

I am an engineer with 13+ years building Python and distributed systems across fintech, smart city, and property management platforms, now focused on AI. I work in two directions: building AI and LLM systems end to end — RAG services, transcription pipelines, and multi-model generation workflows — and AI-assisted development, using agentic coding and workflow automation to design, build, and ship software faster and more reliably. Currently Senior Technical Lead at Fcode Labs; open to senior and architecture roles, and available for freelance AI and backend engineering.
