Engineer, founder, and writer
Building systems people can trust.
I build data platforms and AI products for messy, real-world problems. I like systems that are clear enough to trust, practical enough to ship, and honest about the people they serve.
About Me
I came into technology through data science and psychology. That combination still shapes how I work: I care about the model, the pipeline, and the person who has to make sense of the result.
As an engineer and lead, I like small teams with high trust, direct communication, and enough technical depth to make hard systems feel simple from the outside.
Outside work, Brazilian Jiu-Jitsu keeps me honest about practice, feedback, and pressure. Books do something similar in a quieter way: they give me room to think before turning thought into work.

This is a working snapshot, not a full inventory. I care less about tool lists than choosing the right level of simplicity for the problem in front of me.

The Sigh of Silence
Igor Radovanovic
A published collection of philosophical fragments on solitude, time, the body, silence, and attention.
Writing is part of how I think through complex systems: slowly, precisely, and with respect for what cannot be reduced to a metric.
