Product-focused Backend Engineer with 5+ years of experience building and shipping end-to-end features across Rails and Python. As founding engineer of an AI-powered legal search platform, I architected the full stack from RAG pipeline to AWS infrastructure. Previously led backend development for a top-50 iPad/Mac music app serving 10k+ users. I always take a step back, remember the "why", and allow the user's need to be my guide.
