What we build

Apps, websites and the systems behind them

One team handles the whole stack. We take your product from the first screen design to a release on both app stores.

  • Mobile appsWe build native iOS apps in Swift and SwiftUI, and native Android apps in Kotlin and Jetpack Compose. React Native or Flutter can cover both with one codebase.
  • Web applicationsYour web app, dashboard or marketing site is built in React and TypeScript. It loads fast and works on any screen size.
  • Backends and APIsNode.js services and Cloudflare Workers handle accounts, payments and data for your apps. They are built to stay up under heavy load.
  • New products from scratchWe help you shape the first version, then build it and release it on the App Store and Google Play.
  • Existing codebasesAlready have an app? We review the code, fix crashes, speed up slow screens and plan migrations.

Sudden traffic spikes

A TV mention, a launch or a viral post can bring a rush of people at once. We plan caching, server capacity and fallback screens before that rush arrives.

Real-time updates

Live data, like a price, a vote or a drone's position, is only useful while it's fresh. We build the push and sync systems that keep every device current.

Careful releases

New versions go out in stages, behind feature flags and a release checklist. If a build has a problem, we roll it back before most users see it.

Monitoring

We set up crash reporting, logs and alerts at the start. Problems show up on a dashboard before they show up in reviews.

Your app may never face a national TV audience. The same habits still make launch day calm and keep a growing product steady.

How a software project works

Every project follows five clear steps. You get a written scope up front and working builds to try along the way.

  1. Inquiry

    Tell us what you're building and what exists today.

  2. Scoping call

    We review your designs, code or idea and raise the hard questions early.

  3. Written quote

    Price, timeline and milestones are agreed in writing before work starts.

  4. Build and review

    You try test builds on your own phone at each checkpoint and ask for changes.

  5. Launch and handoff

    We release to the stores and hand over the code and documentation.

Ways to work with us

Choose the setup that fits your project. Each one starts with a conversation and a written agreement.

Common questions

Do you sign NDAs?

Yes. Send it before the scoping call, and we'll sign it before you share any product details.

Who owns the code?

You do. Once the work is paid for, the source code, designs and store listings belong to you. From day one, we prefer to work in your repository and your developer accounts.

Can you work with our existing team or codebase?

Yes. We can audit your current app, fix crashes and slow screens, or plan a migration. One of our engineers can also join your sprints and code reviews.

Do you build for both iOS and Android?

Yes. We build native apps in Swift and Kotlin, or one shared codebase in React Native or Flutter. The right choice depends on your product, budget and team, and we'll recommend one. We also handle App Store and Google Play submission.

How soon can you start?

It depends on our schedule and the size of the work. Your written quote includes a start date. Hourly consulting and code reviews can often begin sooner than a full build.

How do quotes work?

Send the form below, and we'll set up a scoping call. After the call, you get a written quote with the price, timeline and milestones. Nothing is billed until you approve it.
