About Me
About.p1
My journey has led me to design complex ML pipelines, build production-grade models, and deploy AI solutions on cloud infrastructures. I combine strong software engineering foundations with cutting-edge AI research.
Today, I develop end-to-end AI systems including recommendation engines, NLP solutions, computer vision applications, and intelligent agents (RAG, Multi-Agent Systems).
