S·00Software studio · South Africa
We design, build and rescue web and mobile software. And we make our own apps.
For founders and product teams: senior engineers from the first scope to the production release. Our first app, Filltide, is in development.
S·01Services
Three ways to work with us
Every engagement is led by the senior engineer who builds it. Pick the shape that fits where you are today.
Apps that demo well and break for real
AI-built or inherited code that falls over under real users. We find the actual failure modes, fix them and harden what’s left.
- Failure-mode audit
- Root-cause fixes
- Tests and monitoring
A senior engineer in your team
We join your stand-ups, own a slice end to end, and leave it tested and documented.
- Hands-on delivery
- Architecture calls
- Code review
S·02Process
How a project runs
Four steps, each ending in something you can hold. You can stop after any of them and keep everything.
Step 1: Scope
A short, paid discovery. We work out what to build first, what could sink it, and what it costs.
You getWritten plan, estimate and risksStep 2: Build
Working software every week, in a link you can click. No status theatre.
You getA demo build every weekStep 3: Launch
Production deploy with monitoring, backups and a security pass before real users arrive.
You getA live, monitored releaseStep 4: Hand over
Docs, tests and a walkthrough. Your team runs it without us, or we stay on.
You getDocs, runbook and a handover session
S·03Standards
How we engineer
No portfolio wall here yet. This is what you can hold us to instead.
- S·03.1
You own everything.
Code, accounts, designs and IP sit in your name from the first commit.
- S·03.2
Working software, weekly.
Progress is something you can click, not a slide deck.
- S·03.3
Senior hands only.
The people you talk to are the people writing the code.
- S·03.4
Tests decide what ships.
Types, tests and review gate every merge. Nothing goes live on vibes.
- S·03.5
AI-assisted, human-judged.
AI speeds the work up. Engineering judgment decides what goes live.
- S·03.6
Straight answers.
Clear costs, real risks, and a plain no when we’re not the right fit.

A mobile app that forecasts the monthly petrol and diesel price change in South Africa before it’s officially announced.
In development · coming soonIn development.
We’ll announce it here when it’s ready to use.
S·05Questions
Before you ask.
Who will work on my project?
Senior engineers only, and you talk to them directly. There are no account managers in between.
Do we own the code?
Yes. Everything lives in your repositories and your cloud accounts from the first commit, and the IP is yours.
How does pricing work?
Scoping is a small fixed fee. Builds are priced per phase; embedded work is a monthly rate. You see the number before we start.
Can you take over an existing codebase?
Yes. We start with an audit, so you know what you have before anyone decides what to change.
Where are you based?
South Africa, working with teams worldwide. Calls are scheduled in your time zone.
Do you only build your own apps?
No. Client work is the core of what we do. Our own apps, starting with Filltide, are a second line of business.
