About
Technical lead with 10+ years building and scaling production software across fintech, marketplaces, SaaS, healthcare, mobile, and AI-enabled products. I've led small teams, designed systems from scratch, modernized legacy codebases, and built revenue-generating products independently.
I'm strongest where product requirements, architecture, and implementation overlap: clarifying what needs to be built, shaping the technical path, collaborating with engineers and stakeholders, writing production code, and shipping maintainable systems that hold up beyond the first release.

Senior Engineer
Turned an early 3D printing marketplace into a scalable product, leading Rails/React development, AWS infrastructure, CI/CD, marketplace features, and a small engineering team.
Co-Founder & Tech Lead
Built the core technology behind a browser session-recording SaaS: DOM mutation replay, Go APIs, WebRTC audio feedback, and proxy tooling.
Senior Engineer
Integrated an acquired company into Formlabs' platform, scaling the Node.js/React application and onboarding a new engineering team to the existing codebase and AWS infrastructure.
Senior Engineer
Shipped a real-time doctor-patient video-call system using Rails, Backbone.js, and Socket.io.
Senior Engineer
Built features for an early NFT social network where creators and collectors showcase digital art — blockchain integrations, WalletConnect authentication, and core social workflows on a lean founding team.
Consultant & Staff Engineer
Modernized the core proprietary software of a multi-million dollar crane and rigging operation — untangling years of undocumented complexity while delivering new features and reducing operational risk.
Staff Engineer
Built fintech product workflows across React internal tools, backend API integration, data modeling support, and React Native mobile development.
Staff Engineer
Led end-to-end development of a real-time on-demand wellness platform, including React Native apps, backend workflows, payments, dispatch, geolocation, and operations logic.
Consultant & Senior Engineer
Collaborated on a music community platform where the hard problem was social: surfacing listening history, tracking engagement, and building an interface where fans could genuinely support and share artists.
Consultant & Senior Engineer
Worked with the team to architect a cohesive AI influencer generation system — integrating Stable Diffusion pipelines, open-source and paid tooling, and production workflows that made consistent character output repeatable at scale.
Simple when simple is enough. I look for the clearest technical path that solves the real problem without adding unnecessary weight. The best solution is usually the one the team can understand, ship, and maintain.
Where product meets engineering. I work well where user needs, business constraints, and technical execution overlap. That is usually where the important tradeoffs happen.
Build to clarify. A working prototype reveals unclear requirements faster than a long planning cycle. I like to get something real in front of people, learn from it, and improve.
Systems over heroics. A codebase that fights the team slows the product down. I care about clear patterns, shared ownership, maintainability, and reducing future drag.
Order from ambiguity. I'm useful when requirements are changing, systems have grown complicated, or the team needs someone to connect the pieces and create a practical path forward.
Impact over output. Shipping matters, but features are not the goal by themselves. I focus on work that improves users, reliability, business outcomes, or team velocity.
