Hi, I'm Dacheng! 👋

I build practical software with a calm, nature-inspired rhythm: steady, simple, resilient.

Favorite projects:

• dotfiles — My collection of configuration files
• ai — My AI toolbox
• yii2-swoole — A Swoole extension for Yii2
• ziro — Zig Coroutine and Async IO
• tinyproxy-zig — Rewriting TinyProxy in Zig

Hands-on experience:

• Languages: .NET, Java, PHP
• Frontend: HTML, CSS, Vue.js, React, shadcn/ui
• Databases: MySQL, SQL Server
• Servers & Cloud: Linux, AWS, Azure, Alibaba Cloud
• CI/CD: Jenkins, GitHub Actions
• Project Management Tools: FRP, Gitea, Jira, Redmine
• API Integrations: Banks (CMB, China Bank, ICBC); Payment Gateways (Alipay, WeChat Pay, UnionPay, Stripe); SMS (Twilio, AWS SNS); Email (SendGrid, Mailtrap, Mailchimp, Postmark); Cloud Storage (Aliyun OSS, AWS S3, Azure Fileshare); Oauth (Wexin, Alipay, Google, Apple, Facebook)

Currently exploring:

• Languages & Frameworks: Zig and C, C#/.NET, PHP and Swoole, Java and Spring
• Concurrency: Async I/O, Coroutine, and concurrency model
• System Programming: File, Process, Signal, Thread, and Socket
• Network Protocols: TCP/IP, UDP; HTTP, WebSocket, QUIC; FTP, SSH, MySQL, Redis

Guiding principles:

• Start small and iterate forward
• Solve real-world production challenges
