Independent web and mobile studio

I build apps and get them into people's hands.

Web apps, iOS and Android apps, SaaS products, and WordPress and Shopify sites. You work with one person from the first call through launch, and after it.

Services

What I build

Six kinds of work in two halves. Each one starts with a written plan and ends with code you own.

Build

Something new, from the first sketch to launch day.

  • 01

    Web products

    SaaS platforms, dashboards and product sites. Accounts, billing and an admin panel come built in, not bolted on later.

  • 02

    Mobile apps

    One codebase for iOS and Android. I handle store review, the launch, and the updates that keep it running.

  • 03

    WordPress and Shopify

    Sites and stores your team can edit without calling me. Custom themes, catalogs, checkout and only the plugins you need.

Run and grow

Something already live that needs to keep working and get found.

  • 04

    Product engineering

    For teams that already have a product. I ship features, fix performance and run releases alongside your people.

  • 05

    Maintenance

    Updates, backups, uptime checks and security patches every month. When something breaks, the person who knows the code fixes it.

  • 06

    SEO and marketing

    Technical SEO, page speed, analytics and landing pages. I fix what keeps you off page one and show you what's working.

Process

How it works

  1. Week 1

    Scope

    We talk it through. You get a written plan with priorities and a price.

  2. Weekly builds

    Design and build

    Design and code move together. Every week there is a new build you can click.

  3. Live release

    Launch

    Store review, domain, payments and analytics. I set them up and see them through.

  4. After launch

    Run

    Maintenance, SEO and new features. The same person who built it keeps it running and helps it get found.
