Full-stack software, built to ship.

I'm a freelance full-stack developer working with founders and teams to design, build, and launch web and mobile products — from first sketch to production.

What I build

Full-stack means I can take a product the whole way — front end, back end, and everything that keeps it running.

Web applications

Fast, accessible web apps and marketing sites built with React and Next.js — dashboards, portals, and SaaS products that hold up in production.

  • Next.js / React
  • Server-rendered & SEO-ready
  • Responsive, accessible UI

Mobile applications

Cross-platform iOS and Android apps from a single codebase with React Native — native feel, one team, faster to ship and cheaper to maintain.

  • React Native / Expo
  • iOS + Android
  • App Store & Play submission

APIs & backends

Typed APIs, business logic, and integrations that scale.

Auth & payments

Secure sign-in, roles, and Stripe billing wired in properly.

Cloud & deployment

CI/CD, hosting, and databases set up to just work.

AI features

LLM-powered features integrated where they add real value.

Approach

How I work

A simple, transparent process built around clear communication and steady, visible progress.

  1. 01

    Scope

    We start with a short call to understand the goal, the users, and the constraints. You get a clear plan, a timeline, and a fixed quote — no surprises.

  2. 02

    Build

    I work in focused iterations with regular check-ins and previews you can click. You always know what is done, what is next, and where things stand.

  3. 03

    Ship

    I handle deployment, testing, and the launch details — then hand over clean, documented code so you (or your team) can keep building on it.

Stack

Tools I reach for

A modern, boring-in-a-good-way stack — chosen because it is reliable, well-supported, and easy to hand off.
