Building

skillcraft.ai See which tech skills companies need right now. Stay ahead.

Hey, I'm Trevor. I'm a builder and founder living in Tartu, Estonia. Been coding for over a decade, previously led engineering teams, and writing since 2015. I test new tech early, often before the docs exist. Currently, I'm building productivity tools and startups full-time.

I coach and mentor developers because I want to see you win. Beyond code, I love building great products with clean UX and understanding how technical choices affect the business. If you're stuck on something or need guidance, reach out.

When I'm not staring at code, I'm walking Otto and Pontu (two dogs with wildly different energy levels), playing paddle tennis, or occasionally chess. Did Brazilian Jiu-Jitsu for 7 years before getting bored and switching to paddle.

Introverts can be great leaders too

The best leaders I've worked with were introverts. They listened more than they talked and built stronger teams because of it.
