SDE 3 — Technical Architect
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
