Case studies

Systems we’ve designed,
shipped and kept online.

A selection of backend and infrastructure work. Names and figures are representative of the kind of engineering we do.

A ledger and gateway rebuild that took a strained monolith to 50,000 requests per second with money-grade correctness.

50k rps sustained throughput 99.99% uptime −68% p99 latency

Ingest, enrich and serve 8B events per day with sub-two-second freshness and no data loss.

8B/day events ingested <2s end-to-end lag 0 events dropped

Strangler-fig migration of a decade-old monolith into 140+ services — with zero customer-facing downtime.

Active-active across three regions with automatic failover measured in seconds, not hours.

<30s recovery time 3 active regions 99.995% availability

A focused performance and capacity program that cut the cloud bill by 41% while traffic grew.

−41% cloud cost 2.4M daily users −55% compute

A security program that took a fast-moving product through SOC 2 Type II and HIPAA with zero critical findings.

SOC 2 Type II passed 0 critical findings 100% data encrypted
