Hi, I’m Sergey

I specialize in taming complexity in distributed systems and transforming groups of people into cohesive teams.

In my free time, I host tea ceremonies and devour books. I use Arch, btw.

What You’ll Find Here

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

1. Technical Craft

• Love letters to good code: Nature of tech debt, Recommended pagination for APIs.
• Designing systems that fail gracefully: Error-aware design.
• 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 engineering teams: hired and onboarded dozens of engineers, aligned Chinese and Russian teams to common goals, and shipped both v1.0 and v10 of mission-critical systems.
• 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.)
