The problem

The engineering team had a backlog of hundreds of internal tool requests. Many systems still ran on spreadsheets and email chains.

Staff had started building solutions with chatbots, but they were insecure and only worked on their individual devices.

What we built

One-prompt start

Staff send a one-line prompt, then flesh out the idea with the agent until it works completely.

Build agents

Coding agents generate a full-stack app from approved templates, with the company design system, authentication and logging built in.

Automated checks

Every build runs tests, dependency audits, secret scanning and a POPIA data-handling check before anyone sees it.

Private deployment

Apps deploy as individual services on the company’s own cloud machines, behind VPN and sign-in, with full auditing and logging.

One-tap approval

The dev team gets alerts and notifications every time an app is updated or shipped. Anything that touches production data needs a human yes before it goes live.

Outcome

The backlog went from near infinite to near zero in a few weeks. Engineering now spends its time on the core product.

Everyone in the company is now empowered to build apps and solutions for everyone else to use.
