With over 20 years in tech, I design and architect high-performance distributed systems. I’ve built production systems in Go and led engineering teams—including AI agents as full participants in the process. I speak at conferences and have been at Kinescope for over 7 years, where I serve as CTO.

A 26-Minute Incident and 40 Cards in 12 Days: How Two Agents Became Part of the Team
How we brought autonomous agents into Kinescope's working chats: Ratchet in development and Hoist in infrastructure. Two paths of command execution (a shell inside the binary and argv without an interpreter), guards in code, agent code review instead of Bugbot, real incidents with timelines, an estimate of what this would cost in people, and the recipe.
ArticleOne Undefined Variable and 80 Minutes of CI: Why We Moved Our Ansible Rendering to Go
How a refactor of our Ansible variables ran into an 80-minute gating pipeline and ended with Go rendering: 85 specs across two environments in 3.5 seconds, byte-for-byte parity with Ansible, and a deployment plan on the same SDK.
ArticleSpeeding Up Go TLS to 100 Gbps: kTLS, Zero-Copy, and Production Gotchas
How to squeeze tens of gigabits out of a Go service over HTTPS: why TLS breaks zero-copy, how kTLS works, where moving encryption to the kernel helps, and what we had to change in production.
TalkWhy We Didn't Choose K8s: Staying Efficient and Improving Performance
Article based on a talk at TeamLead Conf: why we don't use Kubernetes in production and how we built operations on systemd, deb packages, and Ansible.
TalkOperations Without K8s
Practical experience operating production infrastructure without Kubernetes: how we moved away from K8s and built a simple, reliable, and efficient system based on systemd and package managers.
TalkServing Content from HDDs: CDN Edge Evolution from File Chaos to Simple Storage
Practical experience building a CDN on regular HDDs: how to solve the problem of billions of small files, optimize disk operations, and how the system evolved from a complex architecture with merge to a simpler solution without background processes.
TalkClickHouse is Slow
Practical ClickHouse optimization experience: from performance bottlenecks to solutions using arrays and data structures. Scaling statistics system.
TalkNo Time to Explain, Just Code!
Practical development approaches and rapid prototyping techniques we use at Kinescope.
