I'm an engineering leader who builds teams, defines technical strategy, and ships products that matter — at companies where the stakes are high and the problems are hard.

Currently Engineering Director at Engine by Starling, the technology division of Starling Bank. I've grown our engineering organisation from 10 to over 100 engineers while leading the architecture and delivery of a cloud-native, API-first SaaS banking platform now deployed to banks worldwide.

At Starling Bank, I led the lending engineering team that scaled our portfolio from £37m to £2bn — building the systems, processes, and team culture to sustain that growth in a regulated, high-velocity environment.

Earlier, I co-founded LearnAware, which gives me a founder's perspective on product direction, resource constraints, and what it takes to build something from scratch. I hold three US patents from an industrial placement at Xerox, where I submitted over 20 invention proposals.

I'm a technologist at heart — with a specialism in JVM systems and cloud architecture — who has grown into a strategic leader. I'm at my best when there's a hard problem to solve, a team to grow, and a market to win.
