Backend technologies: The backends behind our production systems.

Node.js and NestJS on AWS run most of what we have shipped: i-mve, Sharewear, COMPASS, TeckNow and the parking system we built. .NET runs E2P+SEND. Go, Rust and Python handle specific services where they do the job better, and the OpenAI and Claude APIs add AI.

You’re probably here because…

What people usually need when they come to us for this.

Your backend is slow, fragile or hard to change.

Review, then fix in stages.

We read the code and fix the riskiest parts first.

You need a backend shared by web, mobile and partners.

One API for everything.

The pattern behind i-mve, serving 523 companies.

Part of your system can’t keep up.

The right language for that part.

Most of a product runs well on Node.js. A busy service might suit Go, a heavy data step Rust or Python. We’ll say which, and why.

What we build on the back end

APIs, integrations and the infrastructure under them.

Integrations

Accounting, payments, couriers and lead platforms.

Device backends

Events from cameras, barriers and NFC tags.

Parking and Sharewear.

AWS hosting

Deployment, storage, monitoring and backups.

How a build runs

The same steps on every project. You approve designs before we write code.

  1. 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.

  2. 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.

  3. Week 1

    Onboarding

    A kick-off meeting, a shared Slack channel and access to the repository. Rehan is your day-to-day contact.

  4. Design

    Designs you approve

    We design the main screens and journeys first. Nothing gets coded until you have signed the designs off.

  5. 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.

  6. 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It depends on scope, so we do not publish a price list.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

  • You need a backend built, fixed or extended
  • Several apps or partners need the same data
  • You want an honest language recommendation
  • 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

★★★★★
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.
Alfonso G.Founder, Mebag · 🇮🇹 Italy
★★★★★
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.
Lisa RubleLicensed Psychologist, COMPASS for Autism · 🇺🇸 Muncie, Indiana
★★★★★
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 choices, cost and how we work.

Ask us something else
Do you work in Go, Rust or Python?

Yes, for specific services inside larger systems: Go for busy APIs and workers, Rust for performance-critical components, Python for data and automation. Java we take on to connect and modernise existing JVM systems.

Node.js or .NET?

Node.js is our main backend and shares TypeScript with an Angular front end. .NET fits organisations on Microsoft infrastructure or with complex typed business rules, as on E2P+SEND.

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.
