Reports time out and pages slow down as data grows.
Indexes and query fixes first.
Most slowdowns are fixed without touching the app. We check before recommending bigger changes.
Database technologies: The data layer under everything we have shipped.
MongoDB sits behind i-mve, COMPASS, TeckNow, Rezi24 and the parking system we built. PostgreSQL runs Sharewear, the ELA platform and QRPixel. E2P+SEND runs on Microsoft SQL Server. We design the data model first, because it decides what the product can do later.
Databases we use
These no longer have separate pages; this page covers them all, with how often we use each.

You’re probably here because…
What people usually need when they come to us for this.
You are moving systems and years of data must come with you.
Migration, checked with your team.
Data mapped, moved and checked against what your team knows to be true.
You aren’t sure whether to use MongoDB or PostgreSQL.
A straight answer.
MongoDB where records vary in shape; PostgreSQL where relationships and reporting matter most.
Customer data is duplicated across systems.
One source of truth.
We agree which system owns each record and clean up the rest.
What we do at the data layer
Design, migration and performance.
Data model design
Collections or tables designed for the product, including multi-tenant separation.
i-mve, 523 companies.
Migrations
Moving data between systems or databases without losing it.
Performance work
Indexes, query rewrites and caching.
Encryption and access
Sensitive fields encrypted and access limited by role.

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 app is slowing down as data grows
- You are moving data between systems
- You are designing the data model for a new product
- You want to own the code and data
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

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 choices, cost and how we work.
Ask us something elseMongoDB or PostgreSQL?
We use both in production. MongoDB suits records that vary in shape and fast-changing products, as on i-mve and COMPASS. PostgreSQL suits strong relationships and reporting, as on Sharewear and QRPixel. We recommend per project.
Do you work with MySQL or SQL Server?
Yes. Microsoft SQL Server behind .NET systems like E2P+SEND, which we built and deployed on Azure, and MySQL on the PHP and Laravel apps we take over.
Can you fix a slow database without rewriting the app?
Usually. Indexes, query rewrites and caching fix most performance problems. We tell you if a schema change is needed.
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.
