About me

I turn complex research into production-grade AI. With a strong background in Computer Vision and NLP, I now focus on building Agentic Systems and Generative AI solutions.

Beyond code, I focus on architecture and impact. I have engineered multi-agent workflows and hybrid retrieval systems that solve ambiguous problems, prioritizing observability and reliability in production.

  • Architected autonomous multi-agent systems using LangGraph.
  • Led a 20-person MLOps team for large-scale data initiatives.
  • Optimized RAG pipelines reducing latency by 10x.
  • Ranked Top 3% Kaggle Expert.

My stack: PyTorch, LangChain, LangGraph, FastAPI, Docker.
