Senior🎓
Top SchoolMarius Onofrei is a lead software engineering consultant with 11+ years building high-throughput, low-latency financial engines and large-scale, cloud-native e-commerce platforms across frontend and backend stacks. Comfortable in TypeScript/JavaScript and C#, he architects event-driven, observable systems and has delivered everything from WPF client conversions to distributed microservices on Azure and AWS. He combines hands-on optimization experience—tuning TCP stacks and using WinDbg for production debugging—with modern CI/CD and automated testing practices, leading platform rewrites and migration cutovers. A pragmatic team player who frequently steps into technical lead roles, he improves delivery through better Agile practices and outside-in test strategies. Based in London, he also experiments with Python and Go on constrained devices like Raspberry Pis, reflecting a persistent curiosity for resource-efficient engineering.
