Full-stack product engineering
I ship polished experiences in React/TypeScript and build the backend systems that power them (Node.js/NestJS, events, APIs).

About
I'm a staff-level engineer with 20+ years of experience across frontend, backend, cloud, and developer experience. I'm an all-rounder by choice: I enjoy owning the whole loop from product intent and UX, to architecture, implementation, and operations.
A recurring theme in my career is building tools that improve processes. I automate repetitive work, create clear patterns, and raise the quality bar so teams can ship faster without losing reliability.
Based in the San Francisco Bay Area, I've worked with companies ranging from startups to large-scale platforms, always focusing on pragmatic solutions that deliver real value.

What I do (and how I help)
I combine technical depth with product thinking to deliver complete solutions that teams can build on.
Developer tooling & process improvement
I build internal platforms, automation, and reusable libraries that reduce friction and make delivery predictable.
Pragmatic architecture
I design systems that are easy to operate and evolve, with clear boundaries and performance in mind.
Applied AI when it matters
I integrate LLM-enabled workflows and retrieval patterns when they meaningfully improve UX or team productivity.
