Full-Stack Software Engineer

I love coding, exploring new technologies, and paying attention to code quality, clean structure, and neat implementation details — currently pursuing a Master’s at UTS in Sydney.

What I've Shipped

Production systems built end-to-end — from editor internals to AI-driven document tooling for global pharma.

  1. Hackathon Builds in 2026

    Recently, I've joined some hackathons and built a few interesting things.

    These projects are small but practical experiments around AI products, education, job search, and developer tooling.

    Lingua Mate

    Personal AI Learning Tool

    View project
    • Built a Codex skill that turns English videos or podcasts into local language-learning web pages.
    • Supports local media files plus concrete Bilibili and YouTube video URLs, then extracts audio and transcribes with Whisper.
    • Generates transcript chunks, Chinese translations, connected-speech notes, vocabulary notes, and validated lesson JSON.
    • Links finished lessons into a local Vite learner app for browser-based study.

    Offer Pilot

    Codex Hackathon

    Built an autonomous job-search assistant that reads a candidate CV, ranks roles by fit, explains match details, and helps generate tailored resumes.

  5. Recently I'm contributing to the open source community.

    Checkstyle and Checker Framework have been my main focus: refactoring code, fixing bugs, and resolving static-analysis violations in mature Java tooling.

    Open Source Static Analysis Contributions

    Checkstyle · Checker Framework

    View project
    • Merged Checkstyle fixes for Checker Framework nullness violations, Error Prone warnings, and PIT mutation suppressions.
    • Contributed Checker Framework fixes around Nullness analysis and KeyFor propagation behavior.
    • Worked through review cycles in established open-source repositories with strict static-analysis and regression-test expectations.

    Clinical Trial AI Agent for MS Word

    Alpha LifeSci Tech

    • Synchronised medical TFL tables between remote data and Word documents; optimised the algorithm and added a Pinia caching layer.
    • Shipped LLM-powered document translation that preserves Word styling, augmented by domain-specific medical dictionaries.
    • Built AI one-click content generation with custom prompt engineering tuned per client.
    • Automated bilingual abbreviation detection and compilation across English and Chinese.

    Collaborative Rich-Text Document System

    Alpha LifeSci Tech

    • Designed a distributed approval engine with electronic signatures and read-only commenting that resolved cross-node consistency issues.
    • Built a custom global search using WebWorker offloading for real-time results without blocking the main thread.
    • Engineered a high-performance table system (drag-resize, custom styling) achieving 95% unit-test coverage.
    • Implemented core editor features (selection, amendment mode, WebSocket sync) and resolved memory leaks via virtual lists.
