PROFILE

Vasil Kotsev

Worked on the SoftUni-Internal/OpenJudgeSystem repository, delivering four features over three months focused on CI/CD automation, deployment reliability, and access control. Developed and enhanced TypeScript project testing and build strategies using Mocha and ESBuild, and implemented GitHub Actions workflows to automate deployment, testing, and issue tracking. Addressed production deployment constraints by optimizing runner disk space and streamlining feedback cycles. Improved contest visibility and access control by introducing type-safe enums and constants in C# and ASP.NET, ensuring accurate contest listings based on user permissions. Demonstrated a methodical approach to backend and full stack development, emphasizing workflow configuration and robust release processes.

December 2025 monthly summary focusing on key accomplishments in the SoftUni-Internal/OpenJudgeSystem repository. Highlights include delivering a new TypeScript project testing and build strategy using Mocha for unit tests and ESBuild for bundling, along with updated configuration to support the new strategy and module paths; implementing a clean-runner step in production deployment to optimize runner space; and driving deployment reliability and faster feedback cycles through these pipeline optimizations. Production deploys faced disk-space constraints; the changes lay groundwork for more robust releases.
