What I bring to a team
Speed to production
Web and mobile products in TypeScript, React Native, Next.js, Node.js and Python that ship this week, not next quarter.
A founder’s instincts
I’ve built, priced and marketed my own products, and had one acquired, so I build for conversion and retention.
End-to-end ownership
From Figma to deploy, including SEO, analytics and A/B tests.
