At Instituto Tecnológico de Sonora, I developed a desktop application to organize information and speed up searches, using Java, Spring Boot, and MySQL. I also implemented CI/CD practices that cut deployment times by more than 80%.

For another Instituto Tecnológico de Sonora project, I developed a mobile application for tourist attractions that improved geospatial search efficiency by 70%. I built a Python REST API and integrated OpenWeatherMap to show real-time weather for each location.

At Pastelería Suspiros, I took part in defining requirements and designing test plans, then created and updated test cases throughout the SDLC. This work achieved 80% early defect detection.

At CONAPESCA, I developed a vessel tracking and valid permit management application, including permit status validation and PostGIS geospatial data. At ITG, I adapted an open-source real estate platform, integrated Google Maps, and implemented automated tests. My experience spans software testing and development, with reported improvements of 40% in user experience and 30% in system stability.
