Your JavaScript codebase breaks in ways nobody predicts.
Migrate to TypeScript gradually.
We add types file by file, starting with the code that breaks most, without a rewrite.
TypeScript development: TypeScript front and back, so mistakes show up before users see them.
Angular and NestJS are both TypeScript, so every project on our main stack is typed from the database layer to the screen. That includes i-mve, Sharewear and COMPASS.
How we use TypeScript
TypeScript is part of every project on our main stack.
- Daily
- Regularly
- When it fits
Where it works well
- Codebases that several developers will change for years
- Sharing types between the API and the front end
- Catching mistakes during development instead of in production
- Migrating a JavaScript codebase gradually
Where it breaks down
- Types are switched off with "any" everywhere, which gives false confidence
- A one-off script where setup costs more than it saves
What we use instead
- Plain JavaScriptFor a small script or prototype.
- Gradual migrationTyping an existing JavaScript app file by file.
You’re probably here because…
What people usually need when they search for TypeScript help.
The API and front end keep disagreeing about data.
Shared types.
One set of types used by both sides, so a change on one shows up on the other.
You need TypeScript developers on your team.
Engineers in your stand-up within weeks.
Engineers who work in TypeScript daily, front and back.
What we build with TypeScript
Typed code across the whole stack.
Full-stack TypeScript
Angular front ends and Node.js or NestJS back ends sharing types.
i-mve, Sharewear, COMPASS.
JavaScript to TypeScript
Gradual migration without stopping feature work.
Typed API clients
API contracts that front ends can rely on.
Stricter builds
Strict settings and linting switched on where they help.
TypeScript systems in production
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.

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
It depends on scope, so we do not publish a price list. A build is a fixed quote and a developer is a monthly rate, both agreed 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.
Dedicated engineerMonthly rateA full-time engineer working on your product, priced per engineer once we know the stack and seniority.
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, 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 this?
We’re a good fit if
- Your codebase is JavaScript and hard to change safely
- You want types shared across front and back
- You are starting a new product on Angular or NestJS
- 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
- You want the lowest price above all else, rather than software that lasts
CLIENT RESULTS
358 reviews. 5.0 average.
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 TypeScript, cost and how we work.
Ask us something elseCan you migrate our JavaScript app to TypeScript?
Yes, gradually. TypeScript can sit alongside JavaScript, so we type the riskiest files first and carry on from there while features keep shipping.
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 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.
