01 // about Who I am, what I’ve built, and what I think about all day.

$whoami

Driven by a deep passion for people, technology, and purposeful work. Over 15 years of engineering experience spanning startups to enterprise systems, with a track record of delivering impactful solutions across product, infrastructure, and team-building.

Founder of a successful service-based company, longtime mentor, and community leader behind Minsk.rb and a popular tech podcast. Equally comfortable writing code, leading teams, shaping processes, or teaching the next generation of developers.

These days I spend most of my time at EVY, where we’re building voice-first AI tooling that treats thinking as a first-class verb. The rest goes to advising other founders, writing, and the occasional long walk in Lisbon.

04 // advisory Working with founders & teams.

$./book-a-meeting

I take a small number of advisory engagements each quarter — usually with technical founders building AI-native products, or with engineering leaders preparing for a hard transition (rebuilds, scale-ups, founder breakups).

If that sounds like you, the easiest way to start is a 30-minute call.
