I build retrieval systems and the applications that wrap around them. Most of my time goes to two things: getting an LLM to answer from a source of truth instead of improvising, and shipping the interface that makes that answer useful to someone.

That has meant a LangGraph pipeline over ChromaDB that returns Pydantic-validated JSON so downstream code can trust it, a real-time pose-estimation coach running MediaPipe in the browser loop, and an arbitrary-style transfer model trained on Kaggle when I ran out of local GPU. On the web side I work in the MERN stack and Next.js — auth, protected routes, WebRTC, the parts that break in production.

I'm heading toward graduation in 2027 and looking for work on production ML systems — evaluation and retrieval quality specifically, where the interesting problem is usually measurement rather than modelling.
