Backend & Cloud Engineer · 8+ years building production systems on AWS
Claude Code is my primary development tool. Shipped four production-grade products solo with it in the last 12 months: CostPatrol (123-rule AWS cost SaaS), VowTrust (institutional deal verification platform), Boody (AI nutrition coach), and a quant trading analytics engine.
Most recent: 100+ developer codebase at one of the UK's largest ticketing platforms. 80+ venues, billions of events/year, 4 AWS regions. Built services from scratch, designed the observability stack, and own out-of-hours on-call. Production bugs I caught and fixed via live monitoring have recovered millions of dollars in previously missed revenue.
