About
Hi, I’m Andy.
I’m a senior app developer based in Hertfordshire, with more than 15 years in software development.
I started out as a backend developer, building the APIs, databases and systems behind products, then grew into full-stack and mobile development, taking apps from architecture right through to App Store release.
Today I design, build and launch iOS, Android and web apps for founders, agencies and growing businesses.

How it works
The process
Scope
I map out what V1 needs to do, what it doesn’t, and what it costs. You get a fixed quote before anything is built.
Design
Key screens and user flows are designed and approved, so you can see how the app works before development starts.
Build
Built in focused sprints, with a working build on your phone at every milestone and one developer accountable for delivery.
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
Raised a round? Get your V1 built in a fixed-scope sprint.
Fixed scope, milestone payments and one senior developer from scope to launch. Sprints from £15k.

Frequently asked questions
How much does it cost to build an app?
Most app builds land between £15k and £30k+, depending on platforms, features and backend requirements. Projects start with a V1 Blueprint (£1,500 over 1–2 weeks, credited against the build), which ends with a fixed quote, so you know the total cost before development begins.
How long does it take to build an app?
It depends on the complexity of the app. A simple app that doesn’t communicate with any backend services can take a couple of weeks. Anything more complex, with user accounts, a backend and integrations, usually takes between 3 and 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.
