About
Hi! I'm Jai โ a full-stack Ruby on Rails developer with 10+ years of experience building and scaling production applications across fintech, B2B, and SaaS. I currently lead a 50+ member engineering team and I'm pursuing a PhD in AI & ML.
I can help you with:
- Ruby on Rails (architecture, APIs, debugging, performance)
- Hotwire, Stimulus, Turbo, Hotwire Native
- AI/ML integration (LLMs, RAG, chatbots, embeddings)
- System design and scalable architecture
- Code reviews and best practices
I bridge the gap between industry and academia โ I don't just teach syntax, I help you understand the "why" behind the code so you can solve problems independently. Whether you're stuck on a bug, building your first Rails app, or integrating AI into your project, I've got you.
