About Me

I'm an AI/ML Engineer who likes turning frontier LLM techniques — multi-agent systems, RAG, fine-tuning — into things people can actually use, not just notebooks. I care about the unglamorous parts of the job too: writing evaluations, catching model failures before users do, and being honest about what "production-ready" really means.

My full-stack background (Django, FastAPI, React) means I take projects from idea through to deployed product myself.

For the specifics, my resume and projects below have the details.
