Hi, I’m Sergey

I tame complexity in distributed systems and human teams. For over 10 years, I’ve built infrastructure serving millions of users, led engineers beyond perceived limits, and mentored the next generation of professionals.

In a nutshell: Engineering Manager | Systems Architect | *nix Philosopher.

Also: chronic book annotator, seasoned penguin enthusiast, and tea sommelier.

What You’ll Find Here

A mix of deep dives, hard-won lessons, and occasional whimsy:

1. Technical Craft

• Designing systems that fail gracefully: Error-aware design.
• Love letters to good code: Nature of tech debt, Recommended pagination for APIs.
• Go: Structured logging, context package: A professional’s view.

2. Engineering Leadership

• Growing people who ship: Deep divers, Key employees, Gratitude.
• Architecting systems well: Architecture: modernity, Learning system design today.
• Strategy > hustle: Engineering strategy, Scaling vs net negative churn.

My Journey

• Built systems at scale: CDNs for 20M+ users, data pipelines handling 10K+ messages per second, cybersecurity platforms (SOAR, TIPs).
• Led teams: Hired engineers, aligned Chinese/Russian architects, and shipped v1→v10 of critical tools.
• Taught: University courses (OS, parallel programming, cybersecurity) and mentored dozens of engineers.

I believe any problem is solvable—with enough knowledge and the right people.

Why neexee?

I love Unix philosophy, Linux, and Open Source in general. So I call myself *nix artist or neexee.
