About Me

I began coding at the age of 14, driven by my passion for gaming and curiosity about how websites worked. Over the years, I’ve evolved into a Full Stack Developer who designs and builds modern, high-performance applications for international clients.

I specialize in Front-End development with React.js, Next.js, and Vue.js, while also working on the Back-End with Node.js, Python, and Java. I’ve deployed and maintained scalable systems on AWS and GCP, collaborating closely with cross-functional teams to deliver secure, data-driven solutions.

I’ve worked with leading brands like BBVA, Interbank, and Supermercados Peruanos, building production-grade web and mobile platforms. One of my milestones was developing an internal syllabus management system for UTP, which is now in its second version. I also led the ERP system for Supermercados Peruanos, managing the migration of millions of records from Oracle to Google Cloud Platform.

I take pride in writing clean, maintainable code and applying Agile (Scrum / Kanban) practices to ensure efficient delivery. My goal is to build software that creates real value for users and businesses — let’s build something great together! 🚀
