Hi, I’m Adrian.
Software engineer from Wrocław, Poland. I started in frontend, spent some time in developer advocacy, and eventually moved into full-stack work and solution architecture.
I work as a Solution Architect at Saleor Commerce, where I help clients figure out their commerce architecture and build the harder parts of it. I suffer from agent-induced scattered-brain syndrome, which means I publish a new project every other week.
