What we build
Whatever the product needs, it's built under one roof.
Most projects need more than one kind of engineering. We cover the whole stack, so there's no hand-off between agencies and no gap between the app and the system behind it.
Mobile apps
iOS and Android apps from a single Flutter codebase, with the release pipeline to the App Store and Google Play wired in from the start.
- Flutter
- Dart
- Fastlane
- Firebase
Web platforms
Customer-facing web apps, business dashboards and admin consoles. Rendered on the server where it matters, and fast everywhere else.
- React
- Next.js
- TypeScript
- Tailwind
Backends and APIs
The system of record behind your product: well-modelled data, GraphQL and RPC APIs, real-time messaging, payments and third-party integrations.
- NestJS
- Go
- Rust
- PostgreSQL
- GraphQL
AI automation
AI that does real work inside your business. Agents that take care of the busywork, assistants built into your product, and pipelines that read, sort and act on documents.
- LLMs
- Agents
- RAG
- Workflow automation
Cloud and DevOps
Infrastructure as code, CI/CD on every repository, and separate sandbox, preprod and production environments from the first week.
- Google Cloud
- AWS
- Firebase
- Terraform
- Docker
Developer platforms
The internal tools that make engineering teams faster: environment consoles, code review and CI, delivery dashboards and health monitors.
- Internal tools
- CI/CD
- Code review
- Monitoring
High-performance systems
For when milliseconds and memory matter. Real-time audio and video, signal processing and computer vision, all the way down to C on Linux.
- C
- C++
- Python
- Linux
Something else in mind?
If it runs on software, we can most likely build it. Tell us about it and we'll tell you honestly how we'd approach it.
How we work
An engineering system, not just extra hands.
Writing code is rarely the hard part. Keeping it fast to change as it grows is. Every project gets the same system we run our own products on.
AI-native from the first commit
AI runs through our whole cycle: design, coding, review and testing. That's how a lean engagement moves like a large one, while every change is still reviewed, tested and owned.
Architecture you can see
Clear layers, written-down decisions and rules the build enforces, so the fiftieth feature goes in as cleanly as the first.
Tested on every change
Unit, integration and end-to-end tests run on every change. Nothing reaches production without passing the same checks.
Real environments from day one
You see working software in a live sandbox from the first weeks, and promoting it to production is a single, repeatable step.
Secure by default
Least-privilege access, secrets kept out of code and personal data handled with GDPR in mind, built in rather than bolted on later.
Built to hand over
Documentation, runbooks and a codebase your own team can pick up and keep moving, whether we stay on or not.
Three ways to work with us
Build your product
From an idea to a launched product. We design it, build it, ship it to your users and keep it running.
- Product and technical scoping
- Mobile, web and backend
- Launch and ongoing support
Speed up your team
We plug into your development cycle and set up the pipelines, tooling and review habits that let your team ship faster on its own.
- CI/CD and environments
- Architecture and code review
- Internal developer tools
Automate with AI
We find the repetitive work in your operations and build the automation that takes it off your team's plate for good.
- Process review
- AI agents and integrations
- Measured time and cost savings
Work
Systems we've delivered.
From air traffic control to crypto, healthcare and fintech. Our clients stay confidential, but the results speak for themselves.
Air traffic control
Voice servers that don't drop a call
A radio server reworked to carry far more simultaneous calls on the same hardware, with memory use cut from 70% to 12%.
1,000+simultaneous calls, up from 600
Crypto
A crypto exchange app, in half the time
A large-scale mobile exchange for African and European markets, with payments, identity checks and automated store releases.
6 monthsto deliver, against a 12-month plan
Telecom
Patented echo cancellation
A line echo cancellation algorithm small and fast enough to fit new gateway hardware, protected by international patents.
4×faster than the gateway it replaced
Healthcare
Support that works offline
An offline-first app for a panic-attack helpline, giving people guided exercises when the phone lines were overloaded.
95%fewer calls a day to the helpline
Social commerce
Images that load before you notice
A new resizing and delivery pipeline for a social marketplace, plus scheduled seller payouts through Stripe.
8×faster image loading, with 75% less storage
Our products
We build our own products, too.
Running our own products keeps our process honest. Every practice we bring to client work is one we rely on ourselves.
SVNLabEarly access
Merge requests and CI for Subversion.
Line-by-line review, approvals and CI for teams that live on SVN, running on the server they already have. No migration and nothing exposed to the internet.
- Go
- React
- Connect RPC
- PostgreSQL
RoolaComing soon
It pays to be a regular.
A loyalty app for the cafés, bakeries and bars around you. Customers scan a QR code at the counter and claim rewards in person, and businesses set up their rewards in minutes.
- Flutter
- Next.js
- NestJS
- Firebase
Process
From first call to production.
A clear path with no surprises. You always know what's being built, why, and when you'll see it.
- 01
Discover
A short call about what you need, followed by a written scope with a clear first milestone.
- 02
Architect
We choose the stack, sketch the system and write down the decisions, so nothing important is left to chance.
- 03
Build
Working software in a real environment every week. You see progress rather than hearing about it.
- 04
Run
Monitoring, improvements and new features, or a clean handover to your own team.
