Field notes
What I learn in production: migrations, tooling, architecture. Real cases, with their numbers and the parts that did not work first time.
- No, Your Blog Doesn't Need Kubernetes
Kubernetes is tech’s broken record: it’s been on repeat for years, and “learn this to make it in 2026” influencers keep putting it at the top of the list of must-have skills, the Holy Grail to reach.

- Application Tracking: What It's For and How to Set It Up with Matomo
At the start of my career, I worked mostly on B2B projects, where application tracking wasn’t a core concern. The convention was to build based on direct requests from client companies.

- From 30 Minutes to 5 Minutes of CI: Migrating a Java Backend to Go with Generative AI
For a few years now, in my spare time, I’ve been working on NuCorder : a platform that lets musicians rehearse online together with low-latency constraints. Founded by three musicians, I’ve been responsible for all the technical development and infrastructure from day one.
- Welcome to the Cabestan Technologies blog
After 7 years at Molotov TV — first as a Go backend developer, then as Tech Lead and Engineering Manager — and a stint as Head of Software Engineering at Wiremind on Eventori , their revenue management product for stadiums and concert halls, I’m going freelance to work on high-value topics: architecture, developer experience, CI/CD, cloud infrastructure.
