About Me

April 25, 2025

Introduction

I’m a senior engineer with nearly a decade of infrastructure experience, currently leading projects on the Infrastructure team at XYB. Originally from Estonia, I specialize in designing and maintaining robust systems that enhance user experience, whether for internal teams or external customers.

My technical expertise includes:

Words matter to me as much as code. I truly enjoy writing clear documentation that doesn’t sound like it was generated by an AI. When I explain a technical concept, I aim to provide context not only to my future self, but to anyone else who has ever struggled to grasp something that was perfectly clear at an earlier point in time.
