Jesus Marron

Software Engineer @ FedEx

I like building products that people will enjoy using. Heavily interested in all things performance, distributed systems, and developer tooling.

[About]

Back in middle and high school, I started coding by developing game mods in Lua and creating programs for calculators using TI-Basic. That early curiosity has since evolved into a rewarding career, giving me the opportunity to manage systems and build software for a pest control company, an ag-tech company, and a cloud computing provider.

Currently, I'm enjoying working across the stack. Some days I'm doing database design and others I'm building interactive frontend components. My focus is often drawn to optimizing performance, ensuring reliability, and refining the overall user experience of the product.

I enjoy using Go and Sveltekit for fullstack applications in my own time. Lately, I've been tinkering with Odin, Rust, and Zig for lower level systems programming and game development. Other areas I've been exploring are machine learning, graphics programming, and distributed systems.
