About Me

Who I Am

I'm a Software Engineer specializing in AI/ML systems, backend development, and data-driven products. I enjoy taking ideas from zero to one — designing architecture, implementing APIs, integrating LLMs, and shipping clean, responsive UIs.

My experience spans FastAPI, React, Python, Streamlit, RL environments, and vector search with FAISS. I care about correctness, observability, and building systems that real users can trust, not just one-off demos.
