Building focused tools for browsers, storage systems, and daily technical work.
I build small products and developer tools: Chrome extensions for everyday use, plus infrastructure utilities around S3-compatible storage, diagnostics, and HTTPS traffic inspection.
Products and Projects
A minimalist Chrome extension showing live time across major cities. Version 7.0, updated June 1, 2026.
豆瓣电影评分助手A Chrome extension that shows IMDb ratings and Rotten Tomatoes freshness directly on Douban movie pages.
s3-turbo-listHigh-performance S3-compatible bucket listing, tracing, diffing, checkpoint/resume, and Parquet export tool.
storageopsObject storage diagnostic system for inspecting S3-compatible behavior and operational signals.
https-traffic-inspectorHTTPS traffic inspection workbench for request analysis and compatibility testing.
Profile
Practical software with a narrow job and a clear owner.
The current portfolio has two public Chrome extensions: World Clock for quick timezone checks, and 豆瓣电影评分助手 for bringing international movie ratings into Douban pages.
On the developer-tool side, the main GitHub projects are s3-turbo-list, storageops, and https-traffic-inspector: listing performance, diagnostics, compatibility checks, tracing, export workflows, and request inspection.
Focus Areas
- Object storage diagnostics and compatibility testing
- S3-compatible listing, tracing, diffing, and Parquet export
- Chrome extension products for small everyday workflows
