Full-stack developer
I design and build web apps, mobile apps, and the APIs behind them, from the first scoping call to production. For teams in retail, media, healthcare, and finance, and for products my own team runs.

What I can build for you
Four kinds of work, each shown with the projects behind it.
Web applications
Dashboards, portals, and internal tools in React and Next.js, shaped around how your team works day to day.
Mobile apps
React Native and Flutter apps for customers and field teams, on the same backend as the web app.
Full-stack systems
APIs, databases, auth, payments, and real-time sync, built so the product can grow without a rewrite.
WordPress & marketing
Custom themes, WooCommerce stores, and content sites your team can update without a developer.
Ten years shipping dashboards, marketplaces, inventory platforms, and content systems.
Some of it for teams in retail, media, healthcare, and finance. Some for products my team owns outright, from first commit to paying customers.
Most projects run on two lanes at once: a web app and the mobile app beside it, or a product and the APIs, payments, and real-time systems underneath. I lead both lanes, so the pieces are designed to fit from the first week.

Writing
Long-form notes from building Zesty and client systems: deployment, data design, mobile stacks, and shipping on my own.
How I Actually Deploy: AWS, Dokploy, Coolify, and Self-Hosted Services
A deployment playbook from real production systems: when managed hosting wins, when a self-hosted PaaS wins, how to run Supabase and Convex yourself, and the partial deploy that lied for a month.
One Seam for Money and Stock: The Order Lifecycle Behind Zesty
Six different callers can change a restaurant order. Here is the transaction boundary they all go through, the invariants it enforces, and why side effects live in an outbox instead of the request.
Flutter or Expo? What Shipping Both Taught Me
Five production apps across two stacks, including Zesty, an Expo app that is a staff console and a customer ordering app in one binary. Where each stack paid off and what actually costs you.
From Requirements to Production: How I Ship as a Solo Developer
A detailed solo and freelance delivery playbook: discovery, stack choices, build phases, billing pitfalls, deploy rituals, and maintenance that keeps trust intact.
