Software engineer and product builder

Franklin Jara

Charlotte, NC·Senior Software Engineer @ Medshift

I build software for real users, mostly commerce platforms, product tools, and developer tooling.

At Medshift, I work across frontend, backend, and data. Outside work, I build my own products, learn Zig and Rust through lower-level projects, and contribute fixes to open-source tools I use.

Most of my side projects start with something I want for myself. Cima, for example, grew out of wanting better feedback from my bouldering sessions. When I'm not coding, I'm usually climbing or listening to techno.
