Backend and AI systems engineer who co-founded an AI research startup before finishing his degree — because waiting to build production systems made no sense.

Actively shipping at two organizations simultaneously — architecting RAG backends, LLM inference pipelines, and semantic retrieval at production scale. Independently shipped LexAI: a legal AI with FAISS vector search and zero hallucinated citations across 100+ benchmarked queries.

— Ship first. Optimize second.
— Backend is the product.
— Co-founded a startup. Still hungry.
