Application support at CoMaz OS, tracing live SaaS issues across APIs, tenant data, and deployments.

At Jaguar Land Rover, I owned customer cases from booking through repair and handover, translating workshop findings into clear updates. At Hedin Automotive BMW / Stephen James BMW, I investigated electrical and software-related faults, documented my findings, and escalated difficult cases through BMW TSARA with ISTA evidence.

I co-developed and supported CoMaz OS, a live multi-tenant booking platform, tracing issues across UI behaviour, APIs, backend logic, tenant data, and production configuration. I used logs, tests, and Git/GitHub workflows to reproduce faults and validate fixes, with practical experience of deployments, webhooks, and payment integration.
