Hi, I'm Dionis 👋🏻
2x CTO → Fractional for growing startups.
I'm obsessed with how complex systems work with all their nuances.
Started with the World Wide Web,
20 years writing
code. Then I got hooked on people: how humans collaborate in teams and
push toward business goals (spoiler: it's usually about money).
Now I work with startups on their engineering orgs: ship, hire,
fire, reshape teams, unfuck processes.
7+ years doing this across US and Europe.
Based in Europe with a US LLC, working globally. Fluent in English 🇺🇸 German 🇩🇪 and Ukrainian 🇺🇦
