How I work
Call
30 minutes, free. We find out if it's a fit.
Scope
A written plan and a price within three days.
Build
Working software every Friday.
Launch
Deployed, documented and yours.
Hi, I'm Ergini.
I work alone, on purpose.
No account managers and no handoffs: the person on your first call writes the code. For more than five years I've shipped production software, lately mostly AI.
Working with teams across Europe and North America.
A direct contract, with calls set around your working day.
Questions
Something else? Email me
With me, Ergini, an independent AI engineer and software developer. I scope, build and ship every project myself, with no agency layer and no junior handoff. The person on your first call writes your code.
Every project is priced on its own, so there is no price list. After a free 30-minute call you get a written plan and a price within three days: a fixed price when the scope is clear, or time-based when the work is ongoing or still taking shape.
A single AI feature takes 1 to 3 weeks, agents and automations 2 to 8 weeks, and an MVP 6 to 10 weeks. You see a working demo every week.
Yes, on the engineering side: EU data residency where you need it, data minimization, a deletion path that reaches your vector store, and the logging and human oversight the EU AI Act asks for.
