Your Express app has grown into one big file of routes.
Give it structure.
We split it into modules with validation and tests, keeping the API the same for your clients.
Express.js development
Lean Node.js APIs that 523 companies rely on every day.
Express adds almost nothing on top of Node.js, which is why we like it for APIs and services where you want full control. We type it with TypeScript, validate every request and document the API, so it stays easy to change.
How we use Express.js
Express is in most Node.js backends we build that don’t need NestJS’s structure.
- Daily
- Regularly
- When it fits
Where it works well
- REST APIs for web and mobile apps
- Webhooks from payment providers and third-party tools
- Small services and gateways where you want full control
- Existing Express apps that need a team
Where it breaks down
- Many developers on one backend with no agreed structure
- Business rules spread across route handlers with no tests
You’re probably here because…
What people usually need when they search for Express.js help.
Your API has no documentation.
Swagger from the code.
Every endpoint documented, so front-end and mobile teams stop guessing.
Webhooks go missing and payments don’t match.
Handle them properly.
Signed, logged and retried, so every Stripe or Windcave event is accounted for.
What we build with Express.js
Small, clear APIs that are easy to change.
REST APIs
Typed, validated and documented from the first endpoint.
i-mve and TeckNow.
Payment webhooks
Stripe and Windcave events handled reliably.
The parking system we built.
Integrations
Accounting, email and third-party tools wired in.
i-mve syncs with Xero, QuickBooks and Sage.
Express to NestJS
Moving a growing Express app onto NestJS in stages.
Node.js backends we built with Express
We say plainly which clients we still work with.
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.

TeckNow
An IT service platform in the spirit of ServiceNow: tickets, resolution tracking and service requests for IT teams. TeckNow came to us directly rather than through Fiverr.
- Monthly
- ongoing development
- Angular
- Node.js
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 a build runs
The same steps on every project. You approve designs before we write code.
- 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 it costs
Real ranges from our own projects. Fixed quote for a build, or a monthly rate for a developer.
Smallest project we take$5,000A tightly scoped build with one core workflow.
Typical project$10,000–$30,000Several user roles, integrations and reporting.
Dedicated engineer$2,500/monthA full-time engineer working on your product.
Included as standard
- UI/UX design, approved before any code
- Two-factor login and OWASP Top 10 security practices
- Deployment to production
- Git repositories and written documentation
- Two months of free bug fixes after launch
Not included
- Payment gateways and other premium integrations, quoted separately
- Graphic design, video and animation
- Features added mid-build, logged as extra hours
After the free two months, maintenance is $700 a month. New features are quoted as you need them, or you can have a dedicated engineer from $2,500 a month.
Are we the right team for this?
We’re a good fit if
- You want a lean API you fully control
- You have an Express app that needs a team
- You want it typed, tested and documented
- You want to own the code
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
- The budget is under $5,000
CLIENT RESULTS

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 about Express.js, cost and how we work.
Ask us something elseExpress or NestJS?
Express for lean APIs and small teams. NestJS once several developers share a growing backend. We often start with Express and move to NestJS when the codebase asks for it.
What happens after launch?
Bug fixes are free for two months. After that, maintenance is $700 a month. New features are quoted as you need them, or you can have a dedicated engineer from $2,500 a month.
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.
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.
