About Me

I'm a Software Engineer who enjoys building things that actually work well and look good doing it. I graduated with a BS in Information Technology, specializing in Web and Mobile Development, from Bulacan State University. Since then, I've been focused on writing clean code, learning scalable patterns, and growing as a developer every day.

Previously at SparkSoft Solutions, I worked on data-intensive enterprise applications. I built things like audit logging systems, notification frameworks, and complex dashboards using React, Next.js, TypeScript, and Laravel. I care a lot about writing code that's not just functional but also easy to maintain and fast at scale.

Long term, I want to become a really strong full stack engineer and eventually build SaaS products that solve real problems. I'm always learning, always shipping, and always looking for the next thing to figure out.
