How I work
Four steps, no surprises.
- 01
A call first
We go through the problem on a call. You leave with a clear idea of what I'd build, even if you don't hire me.
- 02
Plan and fixed price
A written scope, milestones and one fixed number. No hourly surprises.
- 03
A demo every week
You see working software every week and steer while it's still cheap to change.
- 04
Handover
Your accounts, your code, docs and a walkthrough video. Two weeks of fixes for anything that breaks.
The stack
The tools I build with, every day.
Automation platforms, AI models, the frameworks I ship in, and the apps your team already works in.
