I love understanding how things work underneath.

Instead of only using frameworks and tools, I enjoy asking:

How was this built?
Why was it designed this way?
Can I build something like this myself?

That curiosity led me from application development into network infrastructure, systems programming, framework design, and open source.

🌙 Lua

Lua is my primary language and the center of many of my projects.

I enjoy Lua not only as a scripting language, but also as an embeddable language for building extensible systems.

I work with:

• Lua
• LuaJIT
• Luau
• Teal
• OpenResty
• Luvit
• Lapis

🛰️ Featured Projects

🌙 Aether Framework

A modular Lua-centric framework for building backend servers and proxies.

Aether explores a different approach to server architecture.

Instead of forcing developers into one fixed runtime or architecture, Aether aims to provide a core where functionality can be extended through modular components.

Modules can provide features such as:

• Routing
• ORM
• Authentication
• Cryptography
• Networking engines
• Proxy functionality

The goal is to let developers assemble their own backend or proxy environment around a lightweight Lua-oriented core.

🌐 L7 Proxy

A Layer 7 proxy project built around OpenResty and Lua, with Rust and Zig native components where lower-level performance or functionality is useful.

🌍 Open Source

💙 Teal

I use Teal, a typed language that compiles to Lua.

While using Teal, I encountered a compatibility issue with a newer Lua version.

Instead of waiting for someone else to fix it, I investigated the problem, implemented a fix, and submitted a pull request.

That became one of my open-source contributions.

If the tool you use has a problem, you can help improve the tool itself.

That's one of the things I enjoy most about open source.
