Turn your idea or prototype into a working product.

Where I’ve worked

What I take care of

The engineering behind your app.

Here are some of the things I can check and improve, whether I’m building your app or helping you finish it.

• Access & data

  Checking authentication, access permissions and Supabase RLS policies: who can read or change each user’s data. I also check for exposed secret keys and credentials.

• Payments

  Testing checkout and subscriptions, including failed payments, webhook retries and duplicate payment events.

• The stores

  Preparing App Store and Google Play submissions, checking release builds and signing, and responding to review feedback.

• Release & handover

  Adding automated tests and error monitoring, with deployment, rollback and handover notes so you can keep the app running.

How it works

Start small. Then decide.

1. Step 1

   A free 15-minute fit check.

   Tell me about your idea or app, your budget and when you need it. I’ll tell you whether I can help. This first call does not include a code review or report.

2. Step 2

   Agree what we’re building.

   We write down what I’ll build or fix, what it costs and when it will be ready. We also agree how to check it works. If the problem is unclear, an audit can help first.

3. Step 3

   Build, test and launch.

   I do the work, test key user journeys such as sign-up and checkout, and help with the launch if it’s included. You get updates, the code and clear instructions.

• Fit checkFree15 minutes to discuss your idea or app and the next step
• Production-readiness audit£400–£750A report on what needs fixing, what comes first and what it will cost
• Focused repair£1,000–£2,000One clear app problem or store-release task, fixed and tested
• App completion & launch£2,500–£5,000Finish the agreed features and fixes for your app’s next release
• New app buildFrom £4,000Your first web or mobile app, built and tested
• Maintenance£250–£500/moA set number of hours each month for existing clients; no 24/7 support

The agreed work on an existing app normally takes 2–4 weeks. New builds depend on what we choose to include. We agree dates before I start. Most updates happen in writing, with calls on UK evenings and selected weekends.
