What I'm looking for

I'm open to on-site opportunities and relocation to the United States, where I can build and support manufacturing, enterprise, and operational technology systems.

At Foxconn, I support four production lines and roughly 50 users, restoring MES/SFC operations during production-critical incidents and delivering permanent C#/.NET, Oracle, API, and traceability fixes.

Through Marrero Consultores, I build end-to-end products including Todos Somos Power, Agent Auditor, and Marrero Crédito, owning architecture, integrations, deployment, and ongoing improvement with Next.js, React, TypeScript, PostgreSQL, Stripe, and Docker.

Previously, I led multi-site technology delivery at Windstar / Super-Gas across nine plants, trained approximately 200 users, integrated ordering with Santander payments and industrial devices, and managed a six-person IT team at Hipergas.
