01
Start from the person
Every feature begins with a real situation — a letter from school, a call to a doctor — and the person who has to deal with it.

About
“Good software should feel calm — and be honest about what it does.”
I’m Vitalli Syvashchenko, a software developer with almost ten years of experience. Under Creative Routine I design and build my own products — right now, the Fluent Logic app for people who are about to start learning English or struggle to make sense of its weird parts.
02
Be honest about AI
Label what is generated, check it automatically, and never present an unreleased feature as finished.
03
Count the cost
Every model call and every database read has a price. I measure them before scaling, so products stay sustainable.
04
Leave it better
Clean code, documented decisions and data that can be rebuilt — so the next release is easier than the last.
