Rockstar🎓
Top SchoolSimon Popugaev is a software engineer with over a decade of hands-on experience building backend systems, full-stack applications, and CI/CD pipelines, currently shaping cloud-native apps at Ziverge. With a strong Scala and Java background from leadership roles at EPAM and active contributions to prominent open-source projects like ZIO and zio-json, he improves macro-based codegen, varargs support, and JSON name-casing handling in high-performance libraries. He pairs systems-level thinking—designing databases, migrations, and integration layers—with practical DevOps skills including GitLab and Kubernetes automation. A former lecturer and mentor in Scala and Java, Simon combines technical depth with an educator’s clarity, rooted in a physics-mathematics education from Saint Petersburg State University. Notably, his open-source fixes touch internal AST parsing and macro configuration, showing an appetite for subtle, correctness-focused improvements that benefit large developer ecosystems.
