Summary
🤩
Rockstar🎓
Top SchoolNikita Simoshenko is a Senior Software Engineer with 11 years of experience, currently delivering backend reliability and maintainability at Microsoft from Czechia. He blends hands-on engineering—contributing bug fixes, refactors, and test improvements to high-profile .NET projects like dotnet/runtime and dotnet/extensions—with team leadership skills developed as a QA lead who scaled testing practices across multiple self-organized teams. Comfortable across the SDLC, he plans strategic epics, builds analytics, mentors engineers, and fills gaps from testing to support to ensure team outcomes. His open-source work includes low-level image decoder fixes in SixLabors/ImageSharp and careful documentation and telemetry cleanups in .NET, showing attention to detail in both performance-sensitive and infrastructure code. Colloquially pragmatic, he often takes ownership beyond his title to negotiate plans with stakeholders and embed better processes in product teams.
