Senior engineering for apps that have to work.
We take on a few projects at a time so each one gets our full attention. Here's what we can build with you.
Mobile app development
One Flutter codebase for iOS and Android, with native Kotlin and Swift work when a feature needs it. We handle the full journey to the stores.
- iOS and Android from one codebase
- Offline-first data and sync
- Maps, live location and geofencing
- Payments and in-app purchases
- Push notifications and real-time updates
- App Store and Play Store releases
Web apps and SaaS
Admin panels, dashboards and full SaaS platforms. We design multi-tenant systems, where many customer companies share one platform with their data kept apart, from day one.
- Multi-tenant accounts, roles and permissions
- Large tables that stay fast with thousands of rows
- Live updates across users
- Subscriptions and billing
- Small, fast-loading web bundles
- Shared code with your mobile app
Backend and APIs
Go and PostgreSQL services that are fast, simple to run and cheap to host. Clear API documentation means your apps and partners can rely on them.
- REST APIs with OpenAPI documentation
- Login, OTP and single sign-on
- WebSockets for real-time features
- Payment gateways and webhooks
- Background jobs and scheduled tasks
- Backups and monitoring
App rescue and performance
We've taken apps from frequent crashes to 99.85% crash-free, and migrated a React Native app to Flutter in three weeks. We start with an audit, so you know exactly what's wrong before you spend more.
- Code and architecture audit
- Crash and freeze fixing
- Speed and battery improvements
- React Native to Flutter migration
- Upgrades for old Flutter versions
- Automated tests and CI/CD

Common questions
If yours isn't here, ask us on a call.
How much does an app cost?
It depends on the features. After a free discovery call we send a written scope with a fixed estimate, so you know the cost before work starts.
How long does it take?
A focused first version usually takes 6 to 12 weeks. We'll suggest the smallest version that proves your idea so you can launch sooner.
Who owns the code?
You do. The code lives in your repository from day one, and everything is handed over when the project ends.
How do we communicate across time zones?
We agree on a few overlap hours each day, give you a weekly demo and keep a shared board, so you always know what's done and what's next.
Do you use AI tools?
Yes. We use AI-assisted tools such as Claude Code, Cursor and GitHub Copilot to write, test and review code faster. Every change is still designed and reviewed by a senior engineer. Your code and data only go into AI tools with your permission, and for sensitive projects such as healthcare we can work without them.
Can you work with our existing team?
Yes. We can join as extra senior engineers, review code, or lead the mobile side while your team owns the rest.
Not sure which service you need?
Describe the problem. We'll tell you how we'd approach it and what it would take.
