Top SchoolNick Neisen is a Senior Software Engineer with a decade of experience building reliable backend systems, embedded firmware, and automation across startups and enterprise teams. He has shipped production Go and Python services for large-scale platforms—including Kubernetes work at Mirantis supporting 200+ node clusters—and improved CI/CD and release automation with GitHub Actions and GitLab pipelines. His open-source contributions include robustness-focused fixes to the high-profile Neovim codebase and quality improvements to 3D printing and cloud messaging projects, showing an eye for error handling and test automation. Nick pairs low-level embedded C/C++ experience (firmware, device SDKs) with cloud-native backend work, and he’s helped move FAAS products to handle billions of requests. Based in Spearfish, SD, he habitually improves developer workflows and documentation to make systems safer and more maintainable. Colleagues rely on him for pragmatic problem solving that bridges hardware constraints and scalable software.
