Summary
👤
Senior🎓
Top SchoolPhu-hiep Duong is a seasoned .NET developer and technical lead based in Paris with over a decade of hands-on experience designing and operating high-availability financial systems. He has driven growth and resilience at Lemonway—moving from production manager to PaySquad technical lead—helping scale payments throughput by 800% while leading cross-functional teams to deliver robust API and UI solutions. His background spans low-latency trading platforms at SGCIB to complex post-trade and derivatives systems, giving him deep expertise in performance, fault tolerance, and heterogeneous deployments. Equally comfortable in backend C#/.NET and modern front-end stacks (Vue, Svelte, TypeScript), he has a knack for turning proof-of-concepts into production-grade products like the Lemonway Dashboard and a secure Hosted Fields payment solution. Colleagues know him as the “deblocker and doctor” who stabilises releases, automations, and incident response under pressure. He combines an engineering degree from Polytech Nice Sophia with a pragmatic, product-focused approach to shipping maintainable systems for finance.
