Product engineering
React and React Native,
down to the native layer.
Web applications, mobile apps, and the Swift and Kotlin native modules underneath them when a project needs something JavaScript alone cannot reach.

What we do
Three things, done properly.
Service
React web application development
Web applications in React and Next.js — customer portals, internal tools, dashboards and SaaS front-ends, server-rendered where the product needs it.

Service
React Native mobile app development
iOS and Android applications from one React Native codebase — including the Swift and Kotlin native modules most JavaScript-only teams cannot write.
Learn more
Service
Backend and API development
The APIs, authentication and data models behind the product. Node and Express where the stack is JavaScript end to end, Laravel where it is not.

Where we go deeper
Most React Native teams stop at JavaScript.
React Native native modules
When a project needs a platform API or a vendor SDK with no React Native package, we write the native module rather than work around it.
- Native modules written in Swift and Kotlin
- Vendor SDK bridging — payments, hardware, biometrics, mapping
- Turbo Modules and the New Architecture
- Native UI components exposed to JavaScript
Performance and scaling
Profiling and fixing applications that have outgrown their original design, wherever the bottleneck sits — client, server or database.
- React render profiling and re-render elimination
- Bundle analysis, code splitting and lazy loading
- Slow query and N+1 diagnosis
- Caching strategy and read-path optimisation
- Core Web Vitals and mobile startup time
CI/CD and release engineering
Automated pipelines so shipping is routine rather than an event, including signed builds for both app stores and staged rollout.
- GitHub Actions pipelines for build, test and deploy
- Automated iOS and Android builds with signing
- Preview environments for every pull request
- Staged rollout and rollback procedure
One codebase
The same product, on the web and in both stores.
React on the web and React Native on mobile share a language, a type system and most of their logic. That is not a cost saving we advertise — it is why a feature agreed on Monday can be in front of your users on every platform in the same week.
- Signed builds submitted to the App Store and Google Play
- Swift and Kotlin modules where a package does not exist
- Startup time and frame rate measured on real devices
- Over-the-air updates for changes that do not need review
Our position
We don’t sell what we haven’t shipped.
Today that means React, React Native and the backends behind them. We’re building toward AI, machine learning and data science — and we’ll say so here when we’ve delivered that work for a client, not before.

Dashed means not yet delivered for a client. Nothing moves to solid until it has been.

What the first four weeks look like.
01Week 1
Discovery and scope
We work through what you are building and who it is for, then write the scope, the deliverables and the technical approach down for you to sign off.
02Week 2
Architecture and setup
Repository, CI pipeline, environments and data model. The skeleton the rest of the project is built on, in your GitHub organisation.
03Weeks 3–4
First working build
A running application you can open, not a design file. From here you see progress every week rather than at the end.
04Week 4
Review and plan
We demo what exists, agree what changes, and plan the next block of work against the scope.
From week five the cycle repeats — build, demo, decide. Read the full process
Insights
Notes on the decisions that are expensive to reverse.
Native modules
Writing a React Native native module in Swift and Kotlin
When no package does what you need, you write the bridge yourself. A complete module on both platforms, the threading rule that catches everyone, and how to tell when you should not write one at all.

Backend
Node and Express, or PHP and Laravel: choosing a backend
We build both, so we have nothing to defend. What is genuinely the same, what actually differs, and the situations where each one is the obvious answer.

React Native
How to tell if a React Native codebase is in trouble
Written for whoever owns the product rather than whoever writes the code: what you can check yourself in an afternoon, what to ask your team, and which warning signs are not actually warning signs.

How we work
No surprises, in either direction.
Hiring a development team from another country is a leap of faith. These four commitments are how we make it a smaller one.
How we work
You own the repository
Code goes into your GitHub organisation from the first commit, not ours. You are never in a position where leaving us means losing the work.
Scope and cost agreed up front
You get a written scope with the deliverables listed. Anything outside it is quoted separately before it is built, not invoiced afterwards.
You talk to the engineers
No account manager relaying questions. You are in the same channel as the people writing the code, and you can ask them anything directly.
Documentation is a deliverable
Setup, architecture decisions and deployment steps are written down as we go, so a new engineer — ours or yours — can pick the project up.
Contact
Start with a conversation.
Send us the problem, not a specification. We read every message ourselves and reply personally — and if we are not the right team for it, we will say so and usually point you to someone who is.
