Senior Flutter developer delivering user‑centric mobile apps with strong architecture and testing focus.
MexicoWhat I'm looking for
I’m a seasoned senior Flutter developer with eight years of professional experience focused on user‑centric app design and robust architecture since 2019.
I founded Goldee in 2012 and have led cross‑disciplinary teams across software, hardware, design, and marketing, collaborating with U.S. companies while based in Mérida, Mexico.
My work includes large‑scale projects with millions of users and hundreds of thousands of downloads; I emphasize CI/CD, testing (unit, widget, golden, integration), performance optimization, and SLO compliance.
I follow SOLID principles, Clean Architecture, TDD, and microservice‑inspired layering; I maintain public examples of my architecture work and prefer roles where I can improve app quality, mentor engineers, and drive technical excellence.
