Software that runs real bookings, real payments, real verification.

I'm Kingstone, a software engineer in Harare. I design and build the systems businesses run on day to day — from the database up to the interface a customer actually uses — and I keep them running after launch.

Three platforms, built and shipped end to end

Architecture, database, authentication, payments, and deployment — I own the whole build, not just the parts that show up on screen.

What this means for your business

The same pieces that power Unicrib and CarRental — verification, payments, reporting — are what most local businesses actually need first.

Booking & payment systems

Websites and apps that take bookings and accept EcoCash, OneMoney, or card payments directly.

Client accounts & verification

Secure logins, role-based access, and ID checks so only the right people get into your system.

Admin dashboards

Real-time reporting so you can see revenue, bookings, and inventory in one place, any time.

Ongoing maintenance

Deployment, updates, and monitoring after launch — not just a handover and goodbye.

How a project actually starts

No jargon, no long proposals. Four steps from first message to a system you're running.

1

Tell me the problem

A call or WhatsApp chat about what your business needs and what's slowing it down today.

2

I scope and quote

A fixed price and a realistic timeline, agreed before any work starts — no surprises later.

3

Build and launch

You see progress as it happens, not just at the end. Feedback gets built in as we go.

4

Maintain and grow

Ongoing support so the system keeps working as your business changes and grows.
