Co-founder & CTO
at Atherio

I build the technology behind Atherio, a platform that delivers real-time leadership insights, turning leadership guesswork into measurable numbers. That's my full-time focus. On the side, I take on a small amount of advisory work helping engineering teams adopt AI properly.

Advisory availability is limited; I keep a few slots open each quarter.

About

I build systems
that build systems

I started in code. Fifteen-plus years in software architecture and engineering leadership taught me that a CTO's job isn't to ship the most code, it's to build the thing that ships it well: the architecture, the standards, the workflows, and the judgment a team runs on. Output is for individuals. Leverage is the work.

I'm the co-founder and CTO of Atherio, based in Timișoara, Romania. Atherio is a platform that delivers real-time leadership insights, turning leadership guesswork into measurable numbers. My job is the system behind it: how it's built, how it scales, what it costs to serve, and how it stays reliable as it grows.

Running a company is my full-time job, so the advisory and speaking I do are deliberately limited. When I take it on, it's because the problem is interesting and I can genuinely move the needle.

Away from the keyboard, I'm an ultramarathon runner with a thing for backyard ultras, the same stubborn, long-game mindset I bring to building a business.

What I do

The day job, and what's left over

Building a company takes nearly all of it. The rest goes to a deliberately small amount of advisory work, on problems where I can actually help.

Building Atherio full-time

As co-founder and CTO, I own the technology behind Atherio, a platform that delivers real-time leadership insights, turning leadership guesswork into measurable numbers by integrating with the tools teams already use.

Selective advisory limited

Through Cycle-Driven Engineering, the operating model I developed across a 5,000-engineer organization, my own company, and consulting teams, I help engineering organizations build systems that compound every cycle. AI is one accelerator inside that system, not the point.

Speaking & teaching

On stage and in the room

Conference speaker and panelist with 200+ talks and workshops delivered, on engineering leadership, AI-assisted engineering, and building systems that scale.

Writing

Architect To CTO

A newsletter on the real transition from writing code to leading systems and teams in the AI era. Honest, practitioner-first, no hype.

Let's talk

I'm heads-down building Atherio, but I keep a few slots open each quarter for work alongside it. If you're introducing AI-assisted engineering, want to turn leadership signals into real data, need an experienced technical partner to lean on, or would love a speaker for your event or meetup, I'd genuinely like to hear about it.
