Every role on a software team, handled by one small studio.
onemanstack is a software studio founded and run by Msizi Shangase. We design, build, deploy and run web applications end to end, and you talk to the person writing the code.
Shipped, live, and ours to show.
Everything here is real. Three are online today and Merxa is next. No mockups, no borrowed logos.

Slot. Bookings that show up.
The booking system we built and run for salons, barbers and studios. Clients choose a time and pay upfront, so an empty chair stops being a surprise.

- 02Fair cancellationsYou set the cutoff. Cancel in time, the refund is automatic.
- 03RemindersSMS and email reminders, plus self-service rescheduling.
What we build.
Four things, done properly. Most projects touch all of them. See the full breakdown
Custom web applications
Full applications built from scratch, from database design to the interface people actually touch.
02Cloud & deployment
Getting an application onto real infrastructure and keeping it running: hosting, containers, CI and sane environments.
03APIs & integrations
APIs that connect your systems to the tools you already use: payment providers, third-party services, internal data.
04Modernising legacy systems
We assess what is there, then rebuild or refactor it into something maintainable, without stopping the business.
How a project moves.
- 01
Discovery
What it needs to do, who it is for and what done looks like, before any code.
- 02
Build
Visible stages, not one long silence. You see progress as it is made.
- 03
Deploy
Live on proper cloud infrastructure, configured to actually stay up.
- 04
Support
Launch is not the finish line. We stay reachable for fixes and the next phase.
One founder today. A team tomorrow.

One person is where we are starting, not where we are stopping.
