Professional Summary

I'm a Frontend Developer with 3+ years of experience building enterprise-grade applications using Vue.js, Nuxt.js, React, and modern JavaScript frameworks. Currently at C3 Interactive Manila, I develop React-based systems for clients in the aviation and financial sectors, focusing on component architecture, state management, and REST API integration.

My development journey began during my studies in Computer Technology and Information Technology at Bulacan State University, where I discovered my passion for creating user-centered digital solutions. Before joining C3 Interactive, I spent over three years at MYCURE building HIPAA-compliant healthcare web applications serving 100+ organizations and handling 50K+ monthly appointments — work that sharpened my understanding of complex workflows and production-grade engineering.

I'm skilled in QA testing and client collaboration, having conducted product demonstrations, provided end-user training, and participated in Agile sprints throughout my career. I have hands-on experience with Cypress for E2E testing and have worked closely with designers and product managers to ship reliable, accessible interfaces.

Prior to my tech career, I built strong communication and customer service foundations working in the food industry — experience that continues to inform how I approach stakeholder collaboration and user empathy. When I'm not coding, you can find me exploring Philippine mountains through cycling and hiking adventures.

My Vision

To become a versatile full-stack developer who creates accessible, user-centered web applications that solve real-world problems and enhance people's digital experiences across industries where thoughtful engineering can directly improve lives.

I envision a future where technology is intuitive, inclusive, and fast — and I want to help build it. My goal is to be at the forefront of modern frontend engineering, building solutions that not only meet technical requirements but truly understand and serve human needs.

My Mission

To continuously expand my technical knowledge and apply my skills to develop elegant, efficient, and user-friendly web solutions while maintaining a commitment to best practices, clean code, and ethical technology development.

I am committed to writing code that not only functions flawlessly but is also maintainable, scalable, and accessible to all users regardless of their abilities. Every project I work on is an opportunity to push the boundaries of what's possible while ensuring that the human element remains at the center of all technical decisions.
