Kohma contributed to the traP-jp/traO-Judge-frontend repository by developing a selectable row feature for ListingTable and implementing a comprehensive editorials management flow, including CRUD operations and improved error handling for editorial content. Using Vue.js, TypeScript, and API integration, Kohma enhanced user interaction and editorial workflow efficiency, introducing confirmation prompts and clearer feedback to reduce data loss risk. In the traPtitech/NeoShowcase repository, Kohma focused on regenerating protocol buffer definitions and updating protoc tooling with Go and JavaScript, improving build reliability and API compatibility. The work demonstrated attention to maintainability, code generation, and robust frontend and backend integration.

Month: 2025-10 — Focused on maintaining protobuf fidelity and modernizing the code-generation toolchain for the NeoShowcase project to reduce drift and improve long-term maintainability. Key features delivered (and bugs fixed): Protocol Buffer Definitions Regeneration and Protoc Tooling Update across gateway and null services. Recomposed generated protobuf code with minor tooling version bumps. Commits: c25a234818ec5194231271b66f1529b7a7d61864 (re-gen proto). Overall impact and accomplishments: Improved build reliability and API compatibility with downstream clients, reduced future regeneration effort, and ensured the codebase stays aligned with latest protobuf ecosystem. This work supports smoother deployments and faster iteration cycles for feature development and integration. Technologies/skills demonstrated: Protocol Buffers, protoc tooling (protoc-gen-es, protoc-gen-go), generated code maintenance, Go and JS tooling, CI validation, and change management.

August 2025: Focused on enhancing list interactions and enabling a robust editorial workflow for problems. Key deliveries include a new selectable row feature in ListingTable and a complete Editorials management flow for problems, including an EditorialsList page, problem editorial editing routes, and CRUD operations with router-based navigation. Implementations improved business value by enabling faster moderation of problem editorials and clearer user feedback. Major bug fixes include improved error messaging when saving editorials fails and a confirmation prompt before deleting an editorial, reducing risk of data loss. The work leveraged React components, frontend routing, and API integration (deleteEditorial), with refactoring to improve maintainability and scalability.
