Monica Tanguma

I am a bilingual English/Spanish technical operations professional with over 15 years of experience in heavy‑duty diesel diagnostics, fleet maintenance coordination, service writing, and vendor management. My background includes Detroit Diesel warranty specialization, ECM/DDEC programming, electrical troubleshooting, and multi‑trade facility maintenance. I have led teams, managed complex repair workflows, and supported fleet operations with a strong focus on safety, accuracy, and efficiency. I excel in remote environments where communication, documentation, and problem‑solving are essential. I am seeking fully remote roles in fleet operations, technical support, service writing, or maintenance coordination where I can leverage my technical expertise and leadership skills.

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.
