Building programming languages from scratch, one bytecode at a time
I'm a systems programmer passionate about understanding how programming languages work under the hood. Instead of just using languages, I build them — implementing parsers, compilers, VMs, and debuggers from scratch.
- 🦀 Writing language runtimes in Rust, C, Go, and TypeScript
- 🧠 Deep diving into JavaScript engines (QuickJS enthusiast)
- 🔧 Crafting parsers, bytecode VMs, and garbage collectors
- 📚 Teaching others through detailed tutorials and open-source projects
- 🌏 Based in China, coding in multiple (human & programming) languages
