About

Hi! I'm Justin, and I'm focused on artificial intelligence solutions and developer education.

→ My core language is Python, and my secondary language is TypeScript
→ My core focus is deep learning for post-training
→ My secondary focus is building Next.js applications
→ My portfolio work lives in @theosis-ai
→ Major open source projects I've contributed to are pinned here

Education and Background

→ MS in AI from Drexel University
→ prior Developer Advocate @ Lightning AI

Note

past work for Lightning AI can be viewed on my Lightning org profile page
