Senior Full-Stack Engineer | AI Products

I'm a senior full stack engineer with 7+ years of experience, and I've shipped two production AI systems for the NYC Department of Education, the largest school district in the US. Right now that means TRAVIS, a conversational assistant for transportation staff, and a serverless AI email triage system for two high volume parent inboxes, both handling real production traffic with guardrails that keep every model output grounded. Before NYC DOE, I was a UX/Frontend Engineer at Verizon and AT&T's Chief Data Office, where I designed and shipped enterprise dashboards: ACO for Azure cost optimization and SUD for physical server utilization. Earlier roles took me through RIT, Freshop, VMware in Bengaluru, and Bizongo in Mumbai. Here's the through line: I love building scalable, accessible component libraries, then wiring them up to real backends and the AI layer between them: retrieval augmented generation, vector search, multimodal classification, and the guardrails that keep model output grounded, so designers and engineers can ship faster together. WCAG 2.1 accessibility isn't optional in anything I build. It's just how I work.

Three pillars

I work at the intersection of AI, design, and engineering. That's the rare spot where I can research a problem, design the fix, and actually ship it to production without losing the plot in the handoff. The unglamorous enterprise tools nobody brags about? Those are my favorite. (This site's chatbot is one of the smaller things I've built!)

A real-time card table for two, built for me and my partner

Uno and Kombio in the browser, on a phone or a laptop. No app, no accounts: you pick a game and send a link. The interesting part is underneath. One Durable Object per room holds the whole game, and every player is sent their own redacted view of it, so an opponent's cards never reach your browser at all. The socket hibernates while you think, which is why it runs at zero cost, and reconnecting is a first class path because phones lock mid hand.
