What I'm looking for

I’m looking for remote opportunities where I can contribute to global engineering teams, focusing on backend development. I want to keep building and debugging Java/Python modules while improving reliability through testing.

I build and maintain backend modules using Java and Python, and I spend a lot of time on testing and debugging to reduce system errors and improve application performance. At QualityTech Solutions, I also handled complex customer inquiries in English, translating tricky problems into clear next steps.

My background combines systems engineering coursework with bilingual communication—English (C1) and Spanish (native)—so I can work smoothly across different contexts. I’ve supported software development work while staying attentive to the details that keep systems running reliably.

I’m currently looking for remote opportunities where I can contribute to global engineering teams, focusing on backend development and dependable, efficient solutions.
