Notes from building things that have to work.
Software, infrastructure, games, and the decisions hiding beneath their interfaces.
Products
Long-running ideas, built in public where possible.
A small set of products where engineering is part of the experience, not a layer hidden behind it.
A puzzle platformer about splitting space, reading systems and finding the rule behind the room.
Game design · Engineering · World buildingInfrastructure for reliable signing flows on Liquid, designed around explicit policy and inspectable state.
Go · Liquid · Applied cryptographyThis publication and the small production platform behind it, built as one continuously tested system.
Next.js · FastAPI · k3sOpen Source
Small patches, maintained tools, explicit tradeoffs.
Work that is useful because it fits an existing system and makes one concrete behavior more reliable.
About
I build systems by following them all the way to the user.
I'm Aleksandr Golovan, a software engineer working across backend systems, infrastructure, developer tooling, and product engineering.
I care about explicit contracts, boring recovery paths, and interfaces that make the underlying model easier to understand. Outside software, I'm building Halver and writing about the work that survives contact with reality.
