About
I build AI products, help shape North Star, and keep the writing close to the work.
I'm Oleksandr Tsepukh, co-founder and CPO at North Star. Spending most of my time trying to understand how technology can shift the arc of human progress — especially through AI, robotics, and longevity research. I back people who chase hard problems with unreasonable persistence.
How I Work
Taste is a practical constraint.
The work gets better when the product, the workflow, and the writing all reinforce each other.
I care about practical AI systems, not demo theater. The interesting part starts after the first version works and you have to keep it useful, legible, and worth coming back to.
I also care about communities because they change what gets built. North Star started from a simple build-together spirit, and I still think that kind of energy matters more than polished positioning.
This site is where the writing, the references, and the current obsessions live in one place.
Current priorities
Practical AI systems
Products and workflows that still make sense after the demo and after the launch thread.
Legible agent tooling
CLI-first setups and tooling choices that keep automation inspectable instead of magical.
North Star and ecosystem work
Creating environments where engineers, founders, and builders can meet, ship, and stay in motion.
Selected Work
A compact view of the work sitting underneath the writing.
The site is writing-first, but the work still needs a place.
