We build software.
Properly.

Custom software for companies that need it built right — web platforms, data systems, mobile apps, internal tools. We take it from the first conversation to production.

[ 01 ]Selected projects

Some of what we've built.

A mix of live systems and projects in active development. We handle design, engineering, and delivery end to end.

ClearWay

Urban Infrastructure Analysis System

An end-to-end data pipeline that processes raw road-surface telemetry from on-vehicle sensors into a GIS web visualisation — engineered for a municipality managing city-scale road infrastructure.

ClearWay GIS dashboard — road surface inspection and drone telemetry visualisation
GridTime — motorsport calendar and scheduling platform

GridTime

Motorsport calendar platform

A cross-platform motorsport calendar aggregating schedules from scrapers and third-party APIs across every racing series. Handles timezone conversion, series filtering, and a high-performance data API. Web app in development — native mobile app (Expo) in progress.

Web development for clients

Production websites for two clients — a driving school and a university student association. Custom-built, deployed to Vercel, with a CMS for content management. No templates.
