Crafting products that scale and delight
Senior Full-Stack Engineer with deep TypeScript/React experience and a solid Python/Node back end. I build fast, accessible UIs, keep APIs and data models sane, and wire observability so wins stick.
About me
I'm a Senior Full-Stack Engineer based in Dallas, TX, with over a decade of experience building products at companies like Envive AI, Scale AI, Tubular Labs, and Amazon Web Services.
My work sits at the intersection of great developer experience and great user experience. I've built design systems to WCAG 2.2, edge-rendered storefronts with measurable performance gains, and AI evaluation tooling that gives brand and safety teams full visibility into model behaviour without needing engineering support.
When I'm not shipping features, I'm thinking about observability, data contracts, and how to make complex systems legible to the humans who rely on them. I hold an M.S. and B.S. in Computer Science from The University of Tokyo.

How I work
Performance First
Obsessed with web vitals, LCP, and TTI. I keep interactions under 200ms even on large data cuts, and I wire observability so wins stick.
Full-Stack Depth
From edge-rendered Next.js frontends with ISR and prefetching to event-driven Node/Python back ends with idempotent webhooks.
AI Safety Tooling
Built red-team scenario builders, RLHF reviewer workflows, and LLM observability dashboards that tie to brand KPIs and safety scores.
Accessibility Champion
Design systems standardized to WCAG 2.2. Keyboard-first review surfaces, semantic HTML, and screen-reader coverage baked in from the start.
Developer Experience
Storybook-driven component libraries, schema contracts between frontend and ETL, feature flags, and experiment panels that speed up iteration.
Data-Driven Engineering
Analytics instrumentation, evaluation run dashboards, slice-and-compare views, and version diffing — making complex data legible to every team.
