From your words to working software
We design, build, and run web, mobile, cloud, and AI software for growing companies. Every project starts with your requirements written back to you in plain English, with scope and price agreed before any code.
- Fixed scope and price
- A demo every week
- You own the code
- Hours that overlap yours
We need a booking app for our three clinics. Patients pick a doctor and a time, and get reminders on WhatsApp. Ideally live before March.
- Scope
- Booking for 3 clinics: doctors, time slots, and cancellations
- Apps
- Android and iPhone for patients, a web panel for the front desk
- Reminders
- WhatsApp messages 24 hours and 2 hours before each visit
- Launch
- Pilot at one clinic in February, all three by March 1
- Not included
- Payments and video visits, quoted separately

What we build
Six practices under one roof, so the people who design your product are the people who build and support it.
Web apps and SaaS platforms
Customer portals, dashboards, and multi-tenant SaaS in React and Node.js, built to be handed over.
Mobile apps
Android and iPhone apps in Flutter, Kotlin, or Swift, from the first release to every store update.
Data engineering and analytics
Pipelines, warehouses, and dashboards that turn scattered data into numbers you trust.
AI and automation
Assistants, document processing, and workflows that plug into the tools you already use.
Cloud and DevOps
AWS, Azure, and Google Cloud setups with CI/CD, monitoring, and access you control.
Support and modernization
Upgrades, fixes, and step by step rewrites of older systems, without a risky big switch.
The right tools for what you're building
We choose for your product, team, and budget, and explain each choice in your brief. Already have a codebase? We work in yours.
Customer portals, dashboards, and SaaS products.
- Interface
- React
- Next.js
- TypeScript
- Fast pages that search engines can read, in code that catches mistakes early.
- Backend
- Node.js
- The same language as the interface, so one team builds each feature end to end.
- Data
- PostgreSQL
- Dependable records and reporting, with no license fees.
- Hosting
- AWS
- Google Cloud
- Cloudflare
- Pay for what you use, and grow without a rebuild.
Examples, not limits. We also work in .NET, Java, PHP, Go, Ruby, Vue, Angular, and more.
How a project runs
Four stages, each with something you keep. You can stop after any of them.
Listen and say it back
Week 1One or two calls to understand the problem. We write it back as a short brief: goals, scope, risks, and what we will not build.
You keep- A written brief you can share
- A fixed quote or a team plan
Design and plan
Weeks 1 to 2Clickable designs for the key screens and a release plan broken into two week milestones.
You keep- A clickable prototype
- Milestones with dates
Build in the open
From week 3Two week sprints with a live demo every week, so you see working software early and can change course cheaply.
You keep- A demo and written update every week
- Access to the code and the board
Launch and look after it
Ongoing, optionalWe ship, monitor, and fix. Then we hand over cleanly, or stay on for support on a monthly plan.
You keep- Handover notes and a recorded walkthrough
- 30 days of fixes after launch
Promises we put in writing
These go into every contract, not only the sales call.
We say it back first
No code is written until you have read our version of your requirements and agreed to it.
The price does not drift
A fixed quote for a fixed scope. If the scope changes, we agree the new number in writing before the work starts.
You own everything
Code in your repository, cloud resources in your accounts, and every piece of intellectual property assigned to you.
You see progress every week
A live demo and a short written update every week, never one big reveal at the end.
The same people throughout
The team that starts your project finishes it. If someone has to change, you hear first, and they hand over properly.
Hours that overlap yours
We agree a daily overlap window with your time zone and hold standups at a time that suits you.
Three ways to work with us
Every quote is in writing. We do not publish rate cards, because cost depends on scope, but you get a number within a week of the first call.
Fixed scope project
For a defined product, feature, or rebuild
- One price, agreed after discovery
- Paid in milestones
- 30 days of fixes after launch
Dedicated team
For ongoing product work
- Engineers, a lead, and QA as you need them
- Billed monthly
- Scale down with 30 days notice
Support and maintenance
For live systems that need care
- Fixes, upgrades, and monitoring
- Agreed response times
- Monthly plan, cancel anytime
Not sure which fits? Describe the work and we will suggest one.
Ask for a quoteQuestions we hear often
Straight answers to what people ask before they hire us.
Yes. Most of our work is remote, so we agree a daily overlap window with your time zone and hold standups at a time that suits you.
Tell us what you want to build
A short note is enough. We reply within one business day with questions, or a time to talk.
