I turn complex problems into platforms teams can reuse.
I’m Atheer Musa. At Lloyds Banking Group, I lead AI-assisted workflows, patterns and MCP offerings within CancaraOS, while helping evolve the Cancara design system across eight brands and React web, AEM, native iOS and Android. I build with TypeScript, React, Node.js and Python—helping teams move faster without trading away accessibility, evidence or control.

About
Engineering depth, with curiosity beyond the day job.
I’m a London-based engineer who enjoys the connective tissue between design, software and organisational systems. Outside work I experiment with native mobile development, Docker, self-hosting and homelab infrastructure to understand how platforms behave end to end.
I also mentor colleagues through Coach2Code, helping people build practical web-development skills and confidence.
