Artem Kuzmin.

I'm a software engineer with a focus on event-driven systems and security. I've spent the better part of my career thinking about what happens to data in transit — how it gets lost, replayed, reordered, or quietly corrupted — and what honest systems say about that.

I work mainly in the Kafka and Flink ecosystem, with occasional detours into the security problems that come with running streaming infrastructure at scale: credential management, topic-level access control, the surprisingly interesting question of who is allowed to produce to a topic and why.

This blog is a place to think out loud about those things, and also about the less glamorous parts of an engineering career — navigating organisations, writing design docs that people actually read, and the slow accumulation of judgment that doesn't show up on a résumé.

I write slowly and infrequently. I prefer a post that says one thing clearly over one that says five things vaguely. You can subscribe via RSS if you want to be notified without checking.
