I build web applications and work as a math tutor in Puerto Rico. That combination shapes how I approach software: break down complex problems, explain decisions clearly, and make the implementation easier to understand.

Teaching math has made clear communication part of my everyday work. I bring that same habit to software: breaking a problem into manageable steps, explaining the reasoning, and helping others follow the solution.

Soy José J. Méndez Rodríguez, ingeniero de software y tutor de matemáticas en Puerto Rico. Desarrollo aplicaciones web con React, TypeScript, JavaScript y Python, y me interesan oportunidades frontend y full-stack.
Mi trabajo como tutor influye en cómo programo y colaboro: descompongo problemas complejos, explico las decisiones y busco que las soluciones sean fáciles de entender y mantener.
