What I'm looking for

I'm looking to lead pragmatic delivery of scalable backend platforms, shape technical direction, and collaborate closely with product and engineering teams in modern cloud-native environments.

I've led backend delivery at CAIS across four core services for an alternative investments platform, including a file-storage service hosting 5M+ files and handling 1000+ requests per second. I also expanded a document library that uses AI to extract and match fund, account, and transaction data.

My work spans high-traffic and business-critical systems at DWP, Goldman Sachs, Expedia, ARM, and SAP. I bring 10+ years in Kotlin and Java ecosystems, distributed architecture, TDD, CI/CD, and pragmatic collaboration; as CAIS Kanban Flow Manager, I helped reduce cycle time by 40% and improve throughput by 30%.
