Four steps. No surprises.
Honest scoping, fast iteration, and you always know where things stand.

Solo expert. Direct line. Don't worry, I got it.
I started Antonis Consulting because I love solving problems with code. Over a decade later, I'm still at it, working with businesses to make tech actually work.
No corporate fluff, no layers of management, no getting passed around. You text me, I answer. You hit a wall, I fix it.
