About Me

Hello!

I'm Felix, an MIT student studying CS.

My main interests lie around performance engineering, and other systems software like compilers and data structure implementations. At its core, I want my work to help other developers. I think these areas of CS dually satisfy that mission and my intrinsic curiosity in a nice way.

This summer (2025), I'll be a software engineering intern at Jane Street. In past summers, I interned at:

• JHU APL: hacking things.
• Neon: creating on a networked component in the Autoscaling system that monitors VM's compute and memory usage.

Check out my GitHub to see some of the software I've written. Two projects that I'm pretty proud of are:

• cargo-unfmt - an "unformatter" that formats Rust code into perfect rectangles. Made for an April Fool's joke where I fix "inconsistencies" in rustc's formatting.
• peapod - a vector that stores enums compactly by storing tags and data separately

Feel free to reach out to me at fpx at mit dot edu.
