JMRCMDNG // SOFTWARE ENGINEER

I build and ship software end to end.

Mobile apps, web platforms, and the systems behind them — from first idea to production. This is a running log of what I’ve built.

[ 01 // ABOUT ]

A bit about how I work.

I work across the stack — product, frontend, backend, and the infrastructure that keeps it running. I care more about shipping something real than polishing something theoretical.

Outside of client and product work, I build my own tools and platforms end to end, including the JuanLobby line of products.
