Who is Mael
I'm Mael, an independent Shopify Plus engineer. Over eight years I've shipped commerce systems for brands and agencies across the US, UK, Europe, and Asia-Pacific.
I work the way teams ship in 2026: Claude Code and Codex in the loop against real repos, Figma exports straight to Vercel, agent pipelines replacing manual ops. I move between frontend, backend, integrations, and AI workflows without waiting for spec docs.
