🧠 Senior AI Engineer | LLM & Agentic AI | Full Stack

πŸ‘‹ About

Senior AI Engineer with deep expertise in designing and delivering production-grade AI systems β€” from machine learning pipelines and retrieval-augmented generation to autonomous agent workflows and full-stack platforms.

I bridge the gap between cutting-edge AI research and reliable, business-ready software: architecting systems that are scalable by design, secure by default, and maintainable long after launch. My focus is simple β€” turn complex data and AI capabilities into products that deliver measurable business value.
