A systems view

Years across code, cloud, and delivery.

No recent work photos, but I did bring this one back from Manila..

I work where software meets infrastructure: backend services, cloud platforms, delivery systems, and the decisions that keep them maintainable.

I currently work as a Cloud Engineer at BT Group. Before that, I contributed across startups and established teams in Malaysia, Singapore, the UAE, Hong Kong, Kazakhstan and the US. An MBA complements my software engineering background with a commercial view of delivery.
