Mobile apps
Native-feel iOS and Android apps from one React Native codebase: push notifications, offline support, camera, payments, maps.
Services
App development for any purpose, on any device
Custom app development for iOS, Android, and the web. One senior team takes your app from idea to the app stores: design, build, backend, launch, and the releases after it.
Startups validating a product. Established businesses putting a tool in the field team's pocket. Founders replacing a spreadsheet with something customers can actually use. We build with React Native so one codebase ships to both stores, and web apps when a browser is the right home.
- iOS and Android from one codebase with React Native
- Web apps, dashboards, and the APIs behind them
- App Store and Google Play submission handled
- AI features where they earn their place, not where they are fashionable
- 25+ years of production delivery, including regulated financial services.
- Production-grade delivery, not prototypes or slide decks.
- Secure-by-default. ISO 27001 advisory capability.
- Direct access to the senior people who do the work. No account managers.
Start with the smallest app worth shipping
Most apps fail by being too big before they are useful. We scope the first release around the one job your users need done, ship it in weeks, and let real usage decide what earns a place in version two.
The architecture is built to graduate: the MVP is not a throwaway, it is release one of the product.
- You own the code and the intellectual property outright
- Fixed scope and price per release, agreed in writing
- Built so the next engineers extend it rather than rewrite it
What we build
Web apps
Dashboards, portals, and internal tools that run in the browser. No install, no app-store cycle, same senior engineering.
Backends and APIs
The part users never see and always feel: authentication, data, integrations, and infrastructure on AWS, built to stay up.
Integrations
Stripe payments, calendars, CRMs, WhatsApp. Your app talks to the systems your business already runs on.
AI features
Search that understands questions, agents inside the product, document handling. Production AI, from a team that ships it.
Releases and support
Store updates, OS releases, monitoring, and a roadmap. An app is a living product, and we stay accountable for it.
From idea to the stores
- 01
Scope
Thirty minutes on the idea, then a written proposal: the smallest version worth building, the timeline, and the price.
- 02
Design
Screens and flows you can tap through before a line of production code is written. Cheap to change now, expensive later.
- 03
Build in releases
Short cycles, working software every week, and a test build on your phone from early on. No six-month silence.
- 04
Launch and iterate
Store submission, analytics, crash reporting, and a roadmap driven by what real users do. We stay for the releases after launch.
Web & app
A selection of my web and app work
Rental marketplaces, brand campaigns, editorial sites, and corporate builds. Designed and built end to end.
The stack
Production code in TypeScript end to end, deployed on AWS with CI/CD. Boring where boring is right, sharp where it counts.

App development questions
How much does it cost to develop an app?
It depends on platforms, screens, integrations, and how much backend the app needs. That is why we scope a smallest-worth-shipping first release and quote it as a fixed price, so the number is real before you commit to anything.
How long does an app take to build?
A focused first release is typically a matter of weeks, not months; bigger products ship in stages. The proposal sets the timeline per release, and you see working builds throughout rather than waiting for a reveal.
Native or cross-platform: which should we choose?
For most business apps, React Native is the honest answer: one codebase, both stores, native look and feel, and roughly half the build to maintain. If your app genuinely needs deep platform features, we will tell you and plan accordingly.
Who owns the code and the intellectual property?
You do, outright. The repositories, the app-store listings, and the infrastructure accounts are set up in your name from day one.
Do we need a mobile app, or is a web app enough?
If your users need push notifications, offline use, or the camera, go mobile. If it is a tool people use at a desk, a web app avoids the store cycle entirely. It is one of the first questions we answer on the call, and the honest answer is sometimes both, sometimes neither.
What happens after launch?
App stores and operating systems keep moving, so apps need updates to stay healthy. We offer ongoing support and releases, or a clean, documented handover to your own team. Either way nothing is locked to us.
