Skills & Tools
Engineering Strategy & Leadership
Building high-trust, high-velocity engineering cultures. Expert in scaling technical organisations, defining career ladders, and aligning engineering roadmaps with business objectives. I champion a 'Lead by Context' approach, utilising ADRs and transparent documentation to empower autonomous teams.
Systems Architecture & Distributed Infrastructure
Architecting for millions of users with a focus on event-driven systems and cloud-native patterns. Deep expertise in Kubernetes (GKE/EKS), serverless paradigms, and distributed data pipelines (Spark, Kafka). I prioritise cost-efficiency and observability as first-class citizens in every design.
Pragmatic Product Engineering
Driving business value through iterative execution and user-centric engineering. I bridge the gap between high-level vision and tactical reality by breaking complex roadmaps into high-impact milestones. I champion a 'Product Engineer' mindset—promoting deep user advocacy within technical teams and leveraging rapid feedback loops, robust telemetry, and decoupled architectures to maintain organisational velocity at scale.
Work Experience
Building for Resilience, Leading with Context.
The Scale & Strategy Era
Leading organisational growth, navigating M&A, and defining the next generation of fintech and compliance SaaS.
