Ivan Matantsev is a pragmatic senior software engineer with eight years of experience building high-throughput cloud systems and a longer history in .NET development. He has shipped production-grade services at Microsoft and RMS, working on high-performance FHIR servers, Azure Redis offerings, and exabyte-scale catastrophe loss calculations that stitch modeling, finance, and UI teams together. Comfortable across the stack, he combines hands-on backend and ML engineering—contributing to ML.NET by implementing in-memory data loaders and improving pipeline testability—with operational ownership of logging, CI/CD and SLA-driven infrastructure. Based in Bothell, WA, he excels at turning complex domain models into reliable, monitored services and is known for moving quickly from prototypes to customer-facing releases. Notably, he blends deep legacy .NET experience with modern cloud-native practices to solve large-scale data and modeling problems.
