Hi, I’m Sergey

Engineering Manager | Systems Architect | *nix Philosopher

I tame complexity — whether in distributed systems or human teams. For 10+ years, I’ve built infrastructure serving millions, led engineers across borders, and taught the next generation of problem-solvers.

Also: chronic book annotator, penguin enthusiast, and advocate for blameless postmortems in life and code.

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, Error hadling guideline, Context package internals.

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, 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.

(Also, the domain was available.)
