Your web app and mobile app each have their own backend, and they disagree.
One API for every client.
We design a single API that the web app, the mobile app and partners all use, so data and rules live in one place.
API development: The backend your app, your partners and your integrations all share.
We build APIs that a web app, a mobile app and outside systems can all rely on: documented, secured and designed so adding the next client doesn’t mean rewriting the last one.
You’re probably here because…
Most API work starts with one of these.
A partner or customer wants to connect to your system and you have no API.
A documented public API.
Keys, permissions, rate limits and documentation your partner’s developers can follow without calling you.
Hardware or third-party services send data you need to act on in real time.
Real-time event handling.
The parking system we built handles camera reads, gate commands and payments for around 25,000 vehicle transactions a month.
The current backend is one tangled service nobody wants to change.
Split it where it helps, not everywhere.
We break out the parts that change or scale differently. Most systems do not need microservices, and we will tell you if yours does.
What we build
Backends and integrations for products with real traffic.
Product APIs
The REST API behind your web and mobile apps, with accounts, roles, validation and a clean data model.
i-mve’s API serves 523 companies.
Third-party integrations
Accounting, payments, lead platforms, couriers and email, wired in with retries and error alerts.
Partner and public APIs
API keys, permissions, rate limiting and documentation for outside developers.
Device and event APIs
Endpoints for cameras, gates, tags and sensors that must respond quickly and fail safely.

Microservices, where they help
Separate services for the parts that need to scale or change on their own.

i-mve
An all-in-one platform for UK removals and storage companies: enquiries, quotes, jobs, staff, invoices, storage and accounting in one place. It started as one removals firm’s system and is now sold on subscription.

Smart parking automation
Car parks that run without staff: ANPR cameras read the plate, the gate opens, and the driver pays through Windcave or Stripe. We built the software and still maintain it.

How an API build runs
We agree the endpoints and data model before code, then build and document together.
- Day 1
A 30-minute call
Bring the problem and how you handle it today. We ask questions and tell you honestly what we would build first. We won’t pitch at you.
- Next
Written proposal and fixed quote
What is in scope, what goes on the backlog, the stack we’d use and why, the timeline and one price.
- Week 1
Onboarding
A kick-off meeting, a shared Slack channel and access to the repository. Rehan is your day-to-day contact.
- Design
Designs you approve
We design the main screens and journeys first. Nothing gets coded until you have signed the designs off.
- Build
Architecture first, then code
We agree the architecture before writing code, then build with updates twice a week on Slack. Any new request is logged as extra hours and reported weekly.
- Launch
Live, handed over, supported
Deployed to production with your Git repositories and documentation handed over. Bug fixes are free for the first two months.
What API work costs
It depends on scope, so we do not publish a price list. Every project is a fixed quote, in writing, after a 30-minute call.
A focused first buildFixed quoteA tightly scoped build with one core workflow, quoted after a 30-minute call.
A full projectFixed quoteSeveral user roles, integrations and reporting, scoped in writing before work starts.
MaintenanceMonthly planBug fixes, updates and monitoring once the free period ends. Scoped to your software on the call.
Included as standard
- API documentation your developers can follow
- OWASP Top 10 security practices and encryption for sensitive data
- Deployment to production
- Git repositories and written documentation
- Two months of free bug fixes after launch
Not included
- Fees charged by third-party APIs you connect to
- Features added mid-build, logged as extra hours
After the free two months, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. Book a call and we will price both.
Are we the right team for your API?
We’re a good fit if
- Several apps or partners need the same data
- You need to connect systems that don’t talk today
- You want the API documented and the code in your repository
- You can give us access to the third-party accounts involved
We’re probably not if
- Requests for new features get reported as bugs so they don’t count as scope
- You mainly need graphic design, video or animation
- You want the lowest price above all else, rather than software that lasts

Platform-level reviews of the agency, not cherry-picked project comments.
What I love about Team7 is that they always say: No worries, we can find a solution. This is the mindset of builders, creators, people who do not have fear, the partner you need if you want to excel.
Working with Mo and his team over the past year has been nothing short of exceptional. I was admittedly sceptical about investing such a large amount, but results exceeded every expectation.
Their responsiveness and willingness to take on our challenging task were impressive.
They are amazing and consistently exceed expectations. They go above and beyond what is asked of them and their communication is top notch, so much so that we joke that they never sleep. The best of the best.
Common questions
Straight answers on stack, security and documentation.
Ask us something elseWhich technology do you build APIs in?
Mostly Node.js and NestJS, and .NET where the system calls for it, as on E2P+SEND. We choose based on your existing system and who will maintain it.
REST or GraphQL?
REST for most projects: it is simpler to secure, cache and document. We will suggest GraphQL only if many different clients need very different slices of the same data.
Do you document the API?
Yes. Every endpoint is documented for your developers and any partners, and the documentation is handed over with the code.
How do you handle security?
Every build follows the OWASP Top 10, with encryption for sensitive data and two-factor login included as standard. We have built systems that follow GDPR and HIPAA data-handling rules. We hold no security certifications, and we will say so if an auditor asks.
Who owns the code?
You do. At handover you get the Git repositories and written documentation. There is nothing tying the software back to us, so you can take it to an in-house team whenever you like.
What happens after launch?
Bug fixes are free for two months. After that, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. We price both on a call.
Who will I talk to, and how often?
Rehan, one of our two founders, is your day-to-day contact. You get updates on Slack twice a week and can see the code in your repository at any time. We split working hours between us to cover US, UK and Australian time zones, and we usually reply within an hour, sometimes the next morning.
