Front-end development
The part your visitors judge you by. It should load quickly on a mid-range phone over mobile data, and work with a keyboard alone.
Typical work
- Design to code, exactly. Pixel-faithful builds from your designs or ours, responsive from 320 px up.
- Performance. Optimised images, minimal JavaScript, and no five-second wait for a hero banner.
- Interface work. Forms with useful validation, tables that sort and filter, dashboards, charts, multi-step flows.
- Content editing. Wiring the site to a CMS so your team can change text and images without a developer.
- Browser and device testing. Chrome, Safari, Firefox and Edge, on phone, tablet and desktop.
Built for your users, not a showreel
Interfaces are built for the devices, connections and conditions your people actually have — a shared PC, a phone on the factory floor, a slow line. The screen used a hundred times a day gets designed before the one used in the demo.
What you get
You get
Clean source code in your repository, a deployment you control, and a short handover guide.
Usual tools
HTML, CSS, JavaScript / TypeScript, React — or plain static pages when that is the honest answer.
Good fit when
You have a design, or a designer, and need it built properly rather than approximately.
Typical timeline
One to two weeks for a small site; four to eight for an application interface.
Not sure this is the right one?
Describe the problem instead of the solution. A short call is usually enough to tell whether it is this, something else, or nothing you should spend money on.

Accounting · Automation
Every new document, on the right desk by morning
A program that checks a government tax portal for hundreds of clients every day, files what is new in a database, notifies the employee who handles that client, and sends the manager one report each morning.
Education · Platform & back end
Python in seconde, taught by teachers who are not programmers
Crescendo Academy: students write and run Python in the browser, the teacher follows a guided path rather than improvising code, and the school can see every change — including one made to an exam question after submissions came in.
Research · Data & analysis
Research data that behaves like a record, not a folder
Our own build, and the one you can click: samples followed from intake to figure, runs tracked by instrument and reagent lot, and the analysis itself on screen — an expression heatmap and a genome-wide association view.
