PROFILE
Full-stack developer who ships production-grade web applications end to end — data model, payments, admin tooling
and interface. Five years of self-taught engineering, now running an independent practice (extropy dev) alongside an
MBO-4 Software Development programme in the Netherlands. Strongest on Next.js, TypeScript and PostgreSQL, with
hands-on experience of the parts that usually break in real systems: concurrent order handling, payment webhooks and
role-based back offices. Portfolio pieces are working products with real carts, checkout and booking flows, not mockups.

Frontend: Next.js (App Router), React, Tailwind CSS, TanStack Query, Zustand, Framer Motion
