I'm Aaron, a California-based freelance full-stack engineer. I build TypeScript and Python web apps end to end, from PostgreSQL schema to React UI to deployment, and I add LLM features where they solve a real problem. Before software, I worked in IT/operations, real estate, and tax preparation, so I'm used to turning messy requirements into working systems.
