About
Hi, I’m Andy.
I’m a senior app developer based in Hertfordshire. I design, build and launch iOS, Android and web apps for founders, agencies and growing businesses: 20+ shipped so far, with over 100k downloads between them.
I’m a founder too. My own apps make £10k a month, so I build every project like it’s my own money: a lean scope, solid foundations and a launch date that holds.
You work directly with me from the first call to the App Store, with no account managers and no hand-offs. I’m also vetted as top 3% talent on Toptal.
How it works
From idea to App Store in four steps.
01
Scope
We agree what V1 needs to do, what it doesn’t, and what it costs. You get a fixed quote before anything is built.
02
Design
Key screens and user flows are designed and approved, so you can see how the app works before development starts.
03
Build
Built in focused sprints, with a working build on your phone at every milestone and one developer accountable for delivery.
04
Launch
Tested, submitted to the App Store and Google Play, and handed over. You own the code, the accounts and the documentation.
For funded founders

Frequently asked questions
How much does it cost to build an app?
The cost depends on the complexity of your app — features, platforms, and backend requirements. After an initial discussion, I’ll provide a clear quote and timeline based on your specific needs.
How long does it take to build an app?
It depends on the complexity of the app, for a simple app that doesnt communicate with any backend services, it could take a couple of weeks. For anything more complex, it could take between 3-6 months
Can you work with an existing app or codebase?
Yes. I’m happy to jump into an existing project — whether it’s improving performance, fixing bugs, or adding new features. I’ll start with a quick audit to understand the code quality and scope.
Do you handle publishing to the App Store and Google Play?
Absolutely. I manage the full deployment process, including store setup, certificates, screenshots, and compliance requirements to ensure your app is ready to launch.
Do you work with clients across Hertfordshire?
Yes. I’m a Hertfordshire-based app developer working with agencies, founders and teams across St Albans, Watford, Hemel Hempstead, Stevenage and the wider UK. Most projects run remotely, with in-person meetings available across Hertfordshire when it helps.
