Your Questions Answered

The common questions, answered below — if you still need help, just reach out.

Full-stack web apps end-to-end — React & Next.js front-ends, Node/Express APIs, databases, auth and Shopify integrations. I've shipped production tooling used by 1,000+ users.

Discover the problem and scope the smallest valuable slice, build it with clean, typed code and tight feedback loops, then ship to production and iterate on real usage.

React, Next.js, TypeScript, Node.js, Express, MongoDB & SQL, Redux Toolkit and Tailwind CSS — plus Google OAuth 2.0, JWT/RBAC and the Shopify API.

It depends on scope — a focused feature can ship in days, a full product in a few weeks. I scope it upfront and keep you updated the whole way through.
