March 2026 — Stabilized the codedang judging pipeline by fixing a public vs hidden test case evaluation bug and introducing a flexible test-case filtering mechanism. The changes reduce intermittent ServerError incidents, improve submission reliability, and give contest authors precise control over which test cases are evaluated.

Month: 2025-10 — Delivered a re-judging workflow for assignments and problems and implemented robust post-test cleanup to improve reliability and performance. Refactored the RabbitMQ module into a shared library to enable reuse across services, enhancing maintainability and consistency.

Month: 2025-05. Focused on expanding runtime support and system readiness. Key accomplishment: PyPy3 runtime support across the application was implemented, enabling PyPy3 as a supported runtime with updated Dockerfile, backend constants, database schema changes, and frontend adjustments. Resource limits and language options were configured to accommodate PyPy3 submissions. This work reduces submission failures and broadens the contributor base. No critical bugs reported this month; minor stability and compatibility improvements were applied in support of the feature.

April 2025 monthly summary for skkuding/codedang focused on delivering in-editor code execution capabilities, stabilizing the runtime, and strengthening the test feedback loop. The work reduced context switching and accelerated iteration cycles for developers, while improving reliability and user feedback during execution and testing.

March 2025 monthly summary for skkuding/codedang. Focused on delivering reliable tooling improvements, expanding debugging capabilities, and aligning status reporting with execution results. Key business value centers on improved user diagnostics, reduced time-to-resolution, and more robust submission and judger integration.

February 2025 (2025-02) monthly summary for skkuding/codedang: Focused on stabilizing build/install workflows and improving architectural modularity for sandbox execution. Key features delivered include the Iris Sandbox Architecture Refactor and Modularity, introducing decoupled sandbox logic from the judge handler and new judger packages/interfaces to improve maintainability of compilation and execution. Major bug fixed was the Build Environment PNPM Installation Fix, switching from corepack enable to npm install -g pnpm to ensure pnpm is correctly installed during deployment and prevent build failures. Impact includes improved deployment reliability, reduced maintenance burden, and a clearer path for future feature delivery through modular design. Technologies demonstrated include PNPM, modular architecture, decoupled components, interface design, and CI/CD readiness.

January 2025 monthly summary for skkuding/codedang. Focused on delivering measurable business value through improved testing, documentation, and queue processing efficiency. Key work established a robust Iris testing infrastructure and CI pipeline, enhanced backend submission service documentation, and introduced priority-based processing for the submission queue. These efforts reduce risk, improve developer productivity, and optimize job throughput.

December 2024 performance summary: Focused on reliability and milestone closure across two repositories. Delivered a bug fix to codedang submission reporting and packaged Team G final deliverables for SWE3028-Fall-2024, enabling evaluation readiness and stakeholder communication. Demonstrated strong cross-repo coordination, code hygiene, and artifact packaging.

November 2024: Delivered key features and improvements across two repositories, with a focus on reporting reliability, documentation quality, and flexible testing capabilities. The work enhances business transparency, reduces maintenance overhead, and enables more robust evaluation of code changes in production-like scenarios.
