I am a Full-Stack Software Engineer with hands-on production experience building modern web applications using Java (Spring Boot) and JavaScript frameworks (React, TypeScript, Node/Express). My expertise spans the full development lifecycle—from designing REST APIs and modeling data in PostgreSQL/MySQL to delivering responsive and accessible user interfaces. In my role at Citibank N.A., I developed tools for FX risk management and currency conversion, while modernizing internal platforms to reduce processing times by ~30% through modular React components and pragmatic refactoring. I also provided analytics solutions for speculative investments leveraging relational databases and internal data sources. Previously, I completed the Tech Equity Collective Tech Prep program, where I built a strong professional network and sharpened technical and communication skills. My journey also includes over five years as a lead dancer, teacher, and choreographer, where I honed discipline, leadership, and the ability to perform under pressure—skills that continue to shape my engineering mindset. I have built and deployed multiple personal projects, including Sport World, a responsive sports-tracking app deployed on Adaptable.io; Toy Store, an e-commerce prototype with full cart functionality; and Code Clear, a developer resource app with authentication flows. These projects reflect my ability to design end-to-end solutions, integrate APIs, and optimize for performance and usability. I bring a bilingual Spanish-English background, collaborative Agile/Scrum experience, and a commitment to delivering clean, testable, and maintainable code. With certifications in Java, React design patterns, Git, and advanced CSS layouts, I continuously refine my technical craft and stay current with modern development practices.
