Top SchoolNikolche Kolev is a Principal Software Engineer based in Seattle with 12 years of experience building developer tooling and backend systems, currently contributing at Microsoft. He focuses on the NuGet and .NET ecosystems, having driven key backend features like a new package type for dotnet tools and improvements to Visual Studio integration in the widely used NuGet.Client repository. Comfortable navigating both product constraints and low-level packaging logic, he has a track record of shipping interoperable tooling changes that simplify package restore and publishing flows. A Jacobs University Bremen computer science graduate, he combines academic grounding with pragmatic open-source collaboration across large, production-grade projects. Notably, he balances deep implementation detail (e.g., asset layout and user-agent correctness) with broader system thinking that improves developer experiences.
