Marco Alexandré Yu Cordero

Software Engineer · Full Stack Developer · Data Scientist San Juan, Puerto Rico 🇵🇷


Software engineer at Strategic Technology Advisors delivering production web and mobile solutions in high-compliance environments. I work across the full lifecycle — feature development, UI/validation, API integration, and reliability improvements — shipping through structured release cycles with a security-first mindset.

Previously led mobile development at the Puerto Rico Seismic Network, building a real-time tsunami alert system from the ground up. B.S. in Computer Science from UPR Mayagüez (2025, GPA 3.75).

I leverage AI-assisted workflows to improve engineering quality and consistency, and I'm passionate about building technology that strengthens Puerto Rico's tech ecosystem.
