Joseph Ellis

I build AI products that hold up in production, and I'd rather measure a system than trust it.

• ✅ Who I am: software engineer in Los Angeles, currently a software engineer at Buildy.ai : social publishing, paid ads, and AI media generation
• 🤓 My journey: started in Python (Data Science) coursework and statistics, went through deep learning and computer vision, now shipping full-stack AI product work in TypeScript and Postgres
• 🚀 My triumph: a multi-agent LLM research framework  where fine-tuned agents learn to persuade, deceive, and track who's lying — evaluated across 499 games, +321% persuasion over baseline
• ⚒️ My skills: TypeScript · Python · React & Next.js · PostgreSQL/Supabase · PyTorch · LLM & agent architecture · OAuth integrations for platforms that don't want to be integrated
• 🇬🇧 My languages: English, plus enough Mandarin to order confidently and understand nothing
• 🫱🏻‍🫲🏽 Work with me: open to interesting problems — particularly the ones where a system is quietly lying about whether it worked → jsphellis.2020@gmail.com
• 🧚🏻 Preferred comm method: email, or a well-written issue. Pronouns: He/Him
