**Hi, I'm Ivan.**

I'm a full-stack engineer from Ukraine, backend first. For 4+ years I've built Node.js and NestJS systems: APIs, queues, PostgreSQL, and the infrastructure they run on.

I started as a backend developer and grew into full-stack work. I still begin with the data and the failure modes, then build the interface on top. On my own projects I own everything from the schema to the deploy, and I write down why each decision was made.

I write notes on how backends behave, the things I had to look up and wanted to understand properly.
