Career

Sixteen years at production scale.

From foundational Java to architecting edge video platforms — the through-line is distributed systems that survive real traffic, and teams that outlast the projects.

45K cameras on edge
1.5M ANPR events / day
1,500 stores covered
  • Leading architecture for the video platform supporting all express stores (~1,500 stores, ~45,000 cameras), with a roadmap to large-format stores — runs on edge K3s clusters with selective cloud export
  • Driving the Total Loss Recovery (TLR) programme — designing systems to link video evidence with loss events for recovery and prosecution workflows
  • Proposed and leading the camera analytics initiative — exploring ONVIF Profile T/S to extract IVA analytics from Hanwha cameras at the edge; designed multi-strategy collection architecture (PullPoint subscription, RTSP metadata parsing, FTP fallback) under 1 Mbps bandwidth constraints
  • Owned architecture from inception for the Incident Prevention platform; led design and implementation of core microservices across a distributed engineering team
  • Designed and built real-time alerting using SSE with Spring WebFlux and Kafka — delivering instant browser notifications to ~200 security hub operators for ~1.5M ANPR events/day and ~3,000 daily fraudulent till transactions
  • Architected the incident reporting system for capturing, correlating, and utilising store incidents (theft, assault) with linked evidence chains for case building and prosecution support
  • Mentor engineers, conduct architecture reviews, and run technical skill-enhancement programmes for the team

Staff Engineer

100 TB processed / day
3 clouds, one pipeline
  • Designed and led CloudHealth — a multi-cloud SaaS platform with highly scalable event-driven microservices, integrating a data pipeline processing ~100 TB/day across modules for cloud cost management and optimisation
  • Drove cross-module architectural decisions optimising data flow for low-latency processing and cost efficiency at petabyte scale

3B+ requests, Black Friday window
35K images / day
  • Led the Curalate content management platform team — built and enabled a team to take over core high-traffic components from a newly acquired startup; platform handled 3 billion+ API requests during 36-hour Black Friday peak windows
  • Designed and built media processing platform handling ~35,000 images/day, replacing the legacy image processing system with a modern, scalable microservices architecture
  • Managed end-to-end ownership transition, delivery planning, and team mentoring across multiple engineering pods
