About
Hi, I'm Mihail Fedorov — most people call me Kolo. I've been doing DevOps and infrastructure for over 20 years, which is long enough to remember when we called it "sysadmin" and nobody had opinions about YAML.
I build and break things at the intersection of networking, automation, and cloud infrastructure. I run my own autonomous system (AS26954), tinker with IoT devices that probably shouldn't be connected to the internet, and share a home with two cats — a Scottish Fold and a British Shorthair. Bachelor's in CS, certified in various things, ordained minister of the Church of the Flying Spaghetti Monster.
Based in Israel, working as an independent DevOps consultant. Previously led infrastructure at SmartFi, advised on Komodo Platform's notary network, and have been everything from security specialist to CTO along the way. Full CV is available here.

How I think about it
Infrastructure should be boring. If you're thinking about it, something went wrong.
For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it?
Prepare your work outside; get everything ready for yourself in the field, and after that build your house.
Is the one who founds his building on righteousness better, or the one who founds his building on the edge of a crumbling cliff?
Things I work with
Beyond the terminal
When not wrangling infrastructure: microcontrollers, vintage hardware repair, solving puzzles, collectible things, food tourism, and an unexplainable fondness for unicorns.
I created the first version of my personal homepage in 2002 — it had its own 88x31 button, a spinning skull gif, and a Garfield comic strip right on the front page. Peak web design. This is the 12th reincarnation, live since February 2026, built with a little help from AI.
