Franklin Jara

Charlotte, NC—Full-stack SWE @ CHP

I build type-safe web apps, product experiments, and small systems that earn their keep. Most of my work lives somewhere between production engineering, open-source contributions, and side quests that start from a real itch.

Lately I'm focused on shipping practical tools with AI where it helps, learning lower-level systems with Zig and Rust, contributing to projects like litter, and turning hobbies like bouldering into software. When I'm offline, I'm probably climbing or listening to techno.

Useful tools over louder demos.
