About

I’m Žan Kovač, a software engineer from Maribor, Slovenia. By day I’m a Senior Blockchain Developer at Protokol, a Web3 development and consulting company; KOVISOFT is where I take on independent work.

I’ve shipped blockchain products end to end since my student days — a parking-payment platform running on a custom chain, SDK and core-protocol contributions, and Alchy CDK, the open-source toolkit that won Alchemy’s SDK Developer Challenge. My open source lives on GitHub; I care about typed code, reproducible infrastructure and software that survives contact with production.
