I've stopped trying to convince people I'm good. I'd rather just show you and let you make up your mind.

I learn, apply, build — then repeat.

Full-stack developer working across web and mobile — Flutter, React, Laravel, Firebase. I care less about what's trendy and more about what works.

Need something that tracks in real time? I built a system that helps commuters follow buses across Bukidnon. Need a full platform built alone, from design to launch, with real client feedback shaping it along the way? That's Megaworld Homes. Need someone who can sit with a client, understand what they need, and turn it into a real system people actually use? I've done that too.

What are you trying to build? Something that needs a developer who can handle the whole picture, not just one part? A team that needs someone who can take a feature from start to finish? Or a project that's stuck and just needs someone to push it forward?

I build, I reflect, and I keep going. Always up for the next thing worth building.

I'm a reliable developer who values clean, maintainable code, clear communication, and delivering high-quality work on time. I continuously learn new technologies and leverage modern AI-assisted workflows to ship features faster without compromising code quality. Whether you need a responsive website, a cross-platform mobile app, ongoing maintenance, or full-stack feature development, I'd be excited to help bring your ideas to life.

I've been doing programming for almost seven years now Through those years I gain so much knowledge, exposed to different challenging situations and became a flexible developer that can create app from different platforms. I believe I have all the experience that a developer should have, from learning new technologies, problem solving, integrating custom or third party APIs. There are so much to say about me and my skills and these are just summary.

As a mobile software engineer, I have worked with different agencies acting as project lead where I had the experience to work with project managers and clients, from planning, and preparing necessary materials, pitches, and development up to deployment.

I also worked as a university instructor for over a year, teaching programming subjects such as Android and iOS Development.

After almost a decade in corporate and tech roles, I’m now shifting into Virtual Assistance to apply the same organizational and support skills in a more flexible and remote setting. My background includes task tracking, admin support, documentation, email management, and basic tech troubleshooting using tools like Jira, ServiceNow, Google Workspace, and CMS platforms. I’m looking to support clients who need someone reliable, detail-oriented, and tech savvy.
