Why the engineering matters

Some software sells. Some changes a day.

We take both seriously — and hold them to the same standard.

"Will it still work when nobody is watching?"

That's the question we build against. A storefront that drops orders costs a business its month. A school platform that loses a record costs a child their place. We engineer for the second case, and everything else inherits it.

That means access control before features, data integrity before dashboards, and a deployment we still answer for six months later. Our school management platform — built with the Rohingya Centre UK and supported by the UK's National Education Union — has been running in production on exactly those terms. See it live.

How we work

Four steps, no surprises.

Same process for a landing page and a platform — only the scope changes.

01

Scope

We map the goal and quote a real rate before a line of code exists.

02

Build

Short cycles, working software each time, no month-long silences.

03

Harden

Performance, security and edge cases — before you call it done.

04

Support

We deploy, monitor and stay reachable long after handover.

The people

You'll know exactly who builds it.

Rates you can say out loud.

Most agencies hide pricing behind a sales call. Ours is on the homepage: $5/hr for catalog and admin work, up to $40/hr for senior engineering — matched to the work, agreed before we start.
