Senior Software Engineer · Bogotá (GMT-5) · Remote
// About me
I'm a Senior Software Engineer based in Bogotá with 9+ years building production-grade backend systems. I've worked across HR-tech SaaS, edtech platforms, and built my own affiliate startup — all sharing one thread: making complex things work reliably at scale.
I led a 4-engineer squad at Crehana, cut cloud costs by 20–25%, and promoted two devs to senior. As a founder at GYDI, I own every layer — from database schema to CI/CD pipelines.
“Good systems aren't hacked together — they're designed with intent, tested with rigor, and evolved with discipline.”
