Tools & Platforms

Go Security Self-Hosted Open Source

A security-first community continuation of CasaOS, focused on safer self-hosting, maintainable upgrades, and transparent hardening.

Swift SwiftUI macOS iOS Node.js Metal

A native NetEase Cloud Music client for macOS and iOS. SwiftUI app with a local Node.js helper process for the API layer on macOS, plus a native encrypted direct-transport (eapi/xeapi) on iOS. Features an offline-testable core, a Metal-rendered audio spectrum visualizer, and 500+ offline unit tests.

Python Data Tool Open Source

A Python data tool that combines network performance metrics, user inputs, and pricing data to estimate mining revenue with visual outputs. The project continues to improve through real community feedback.

Swift iOS Network Extension QUIC/Hysteria2

Built a production-ready iOS VPN app leveraging Apple Network Extension APIs. Integrated a QUIC-based Hysteria2 client with packet-tunnel architecture. Managed the full delivery pipeline: provisioning, code signing, TestFlight distribution, and UI iteration.

Python Bash DHCP/TFTP NFS

Designed a helper tool for deploying diskless Linux compute nodes through PXE boot — orchestrating DHCP/TFTP, boot images, and NFS root configuration with automatic network/rack topology discovery.
