Bryan Romero Chinchilla

Software EngineerBackend & integrations, end-to-end.

I build the APIs, integrations, and systems behind operational software. I started in manufacturing — owning a plant-wide system end-to-end as the sole developer — and have since focused on connecting enterprise and legacy systems, keeping high-availability services healthy, and automating the manual work in between.

About

I’m a software engineer with 6+ years building and integrating the systems operations run on. My path started on the plant floor at Unilever, where I was the sole developer of a plant-wide MES, and moved through manufacturing IT, courier-tracking platforms, and enterprise integrations.

I like getting to the root cause of a problem and then automating it away — whether that’s a script, a monitoring dashboard, or a small AI helper. Lately that’s meant Microsoft 365 automation and applied computer vision, alongside the backend and DevOps work that’s always been my base.
