PROFILE
Shigetaka Shirouchi
Contributed to the team-mirai-volunteer/action-board repository over two months, delivering nine features and resolving three bugs focused on user engagement, data integrity, and developer experience. Developed mission navigation, referral tracking, and UI consistency, while optimizing database queries and onboarding workflows. Enhanced the achievement system by migrating Kyoto prefecture data and correcting XP calculations, and introduced new missions to promote social media engagement and early voting. Improved maintainability through React hooks compliance, Next.js image optimization, and CI/CD pipeline enhancements. Worked primarily with TypeScript, SQL, and Docker, demonstrating strengths in full stack development, migration scripting, and continuous integration within a collaborative environment.

Feb 1, 2026February 2026 (2026-02) monthly summary for team-mirai-volunteer/action-board. Delivered a mix of user-facing missions, stability fixes, and UI polish, with a focus on data integrity, onboarding flow, and contributor experience. Key business value includes restored and accurate achievement data, improved user engagement paths, and streamlined PR creation for forks. Highlights: Key features delivered - Kyoto prefecture support in poster achievements with XP migration: added Kyoto to POSTER_PREFECTURE_MAP, implemented migration to recover Kyoto poster achievements, and fixed XP calculations (TOTAL_XP = 1000 for the migrated window). Commits: 52955e148c3af062ea8e24fa7906ded2c038cbea (migration and XP fixes). - Level-up modal navigation bug fix: prevent the level-up modal from reappearing when navigating back by clearing the Router Cache via revalidatePath("/") after mark-as-seen. Commit: 8821d4fafdb91adc908584498b5b9c025ab67612. - Social media candidate follow mission: added a new mission to follow candidates’ SNS accounts and updated artifact label for clarity. Commit: 7a0ef12b82fb8ca6b29619d514fe6f5c567f1995. - Early voting information mission: introduced a mission to promote early voting with candidate information. Commit: 1c6999e0f411db134f8b08e4b5f82c41384e5834. - Biome configuration cleanup and image handling improvements: refactor for React hooks compliance, remove unused params, upgrade image handling from <img> to Next.js Image; includes multiple lint-related fixes. Commits: f1ec7d7e3f0f082276c2ccb1dcff66b7ae39e2d8 and 8785e9c7e808374a176d8e0171a4544a478099ee. Major bugs fixed - Biome warnings resolved and React hooks compliance addressed; removed obsolete lint rules and adjusted code paths to prevent regressions. (Composite commits: f1ec7d7e3f0f082...; 8785e9c7e80837...). - Level-up navigation bug fixed (see above) to ensure clean UX when using browser back. Overall impact and accomplishments - Improved data integrity and user experience: restored Kyoto achievements with accurate XP, reduced navigation-related UX glitches, and clarified mission labeling for better user understanding. - Enhanced developer experience and maintainability: consolidated biome lint cleanup, prop removals, and image handling improvements reduce future technical debt and enable smoother feature delivery. - Expanded engagement pathways: two new missions (social media follow and early voting) increase user participation opportunities and disseminate civic information. Technologies/skills demonstrated - React hooks compliance, TypeScript lint rule adjustments, and codebase cleanup for stability. - Next.js image optimization and router cache management for reliable UI updates. - Migration scripting and data recovery patterns enabling accurate historical achievements.
