Vision
To be the company Ghana calls when software has to work, and the place its best engineers say they learned the trade.

Why Coterium

Plenty of programmes charge for mentorship. Ours costs nothing, because it happens on client products with a senior engineer reviewing the work.

Juniors do much of the building. Seniors own the architecture and sign off before anything reaches production, so you get the energy without the beginner mistakes.

Ghana sits on GMT, so our working day overlaps almost entirely with the UK and most of Europe. For clients further away, we move our hours.

You get software that works. One of our engineers gets a project they can point to for the rest of their career.
Ghana has no shortage of talented engineers. What most of them never get is real projects, honest code review and a way into the industry. Coterium exists to change that: every project we deliver doubles as the place our engineers learn the craft.

To be the company Ghana calls when software has to work, and the place its best engineers say they learned the trade.

Put junior engineers on live client work under senior review, and ship software our clients can depend on.
stack
We choose tools project by project, and most days we’d pick proven and boring over new and shiny.
services
Most projects need two or three of these. Tell us what you’re building and we’ll say which.
AWS or Azure, set up with Terraform so deploys are automated, outages get noticed and the monthly bill holds no surprises.
Server code, APIs and databases built to cope as usage grows, and documented well enough for your own team to take over.
iOS, Android and web apps, from the first screen to the app store. We mostly build with React, Next.js, Flutter and React Native.
We use AI coding tools where they genuinely save time, and a senior engineer reviews everything they write. Faster delivery, no mystery code.
A monthly retainer covering bug fixes, security updates and small improvements, so your software keeps working long after launch.
Before any code, we talk to your users, map the flows and test clickable prototypes, so we build the right thing first time.
projects
Products we designed and built with our partners, from the first sketch to launch day.

Description:
Proloda lets people book a vehicle and driver to move anything across town, from a single box to a full house. We designed and built the booking flow and the marketing site, and kept testing every screen against one question: does this feel as easy as ordering a ride?
process
Five stages that overlap on purpose, with working progress at each.
team
Engineers, designers and operators based in Accra, working remotely with clients wherever they are.
