I am a bilingual (English/Spanish) technical professional with 15+ years of experience in heavy‑duty diagnostics, fleet maintenance coordination, service writing, and operations management. My background includes Detroit Diesel warranty work, advanced electrical troubleshooting, vendor management, and multi‑site maintenance oversight. I excel in remote roles that require strong communication, problem‑solving, documentation, and coordination across teams and vendors.

I bring deep mechanical expertise, strong customer service skills, and the ability to manage workflows, repair orders, compliance, and technical support tasks from a home office environment. I am seeking fully remote opportunities where I can contribute my technical knowledge and operational leadership.

I completed a Technical Diploma in Heavy Duty Diesel Mechanics from Lincoln Technical Institute, where I trained extensively in diesel engine systems, diagnostics, and ECM programming. I also completed the Stewart & Stevenson Certified Apprenticeship in Heavy Engine Systems and DDEC Module Programming, which strengthened my expertise in electrical systems, warranty procedures, and OEM‑level diagnostics. My education provided a strong foundation in technical troubleshooting, safety standards, and advanced engine technology that I continue to apply in fleet operations, service writing, and remote technical support roles.
