Oleg Goncharov
I build digital tools with a point of view.
Browser extensions, mobile apps and desktop utilities for everyday friction — designed, shipped and kept useful.
Focus
From a sharp idea to a useful product
Small interfaces, clear feedback loops and products that respect people’s attention.
Stack
Web · Flutter · C++
The right technology for the job, with craft in the details.
Rhythm
Build → test → ship
Public releases, closed betas and thoughtful iteration.
Browser extensions
Selected work
A growing shelf of practical digital products.
