March 2025: Focused on improving Japanese IME input reliability and migration hygiene for oat-sa/extension-tao-itemqti-pci. Delivered key fixes and upgrades to enhance user experience and release traceability. Key outcomes: - MathQuill IME Input Handling Fix: improved recognition of special keys for Japanese IME, resulting in smoother input and fewer user-side workarounds. - MathEntry PCI IME Compatibility Upgrade to 2.7.1: addressed IME issues with an irreversible migration; included migration tooling and a cosmetic migration filename rename for clearer history. - Migration tooling and history improvements: added a migration script and updated the migration filename to reflect date, improving release auditability. Impact and value: Higher input reliability for Japanese content, reduced support friction, and clearer historical records for migrations. Demonstrated skills in dependency upgrades, JS/MathQuill integration, and release hygiene.

January 2025: Focused on strengthening build reliability for symlink-dependent routes in sveltejs/kit. Delivered a targeted bug fix that ensures correct symlink resolution in the build process for universal/server routes, improving robustness and reducing potential build-time/import errors. Impact includes smoother CI/dev workflows, fewer breakages in production deployments relying on symlinks, and clearer traceability to issue #12740. Technologies involved include Node.js-based build tooling, symlink handling, and conventional commit-based change management.
