Work
Four recent engagements where I designed, built, or modernised backend systems handling real users, real money, and real compliance deadlines.
Replaced a legacy access control system
Rebuilt a 15-year-old Delphi access control platform as .NET 8 microservices. 1,000+ properties migrated with no service interruptions, handling 10,000 concurrent IoT device connections.
Built a threat detection pipeline processing millions of events/minute
Designed the event streaming backbone for airport and stadium security — millions of telemetry events per minute, sub-second threat alerting, 30% fewer false positives through ML integration.
Halved deployment effort for a government microservices platform
Modernised the infrastructure for a cross-cloud (AWS + Azure) microservices platform used by government services. Cut deployment effort by over 50% while meeting GDS security standards.
Made a cash deposit platform's messaging bulletproof
Re-engineered the event pipeline for a regulated cash deposit platform so that interest rate updates and deposit instructions could never be silently lost, even during infrastructure failures.
