I build efficient
Software Only.
I'm a full-stack software developer who loves building digital products that actually work for people. Right now, I'm focused on creating software that's fast, reliable, and easy to use; the kind of tools that solve real problems and feel good to interact with.
01.About Me
Hi, I'm Kelvin — a software developer passionate about building efficient, end-to-end applications. Ever since creating my first mock website in 2017, I've been driven by a desire to understand and build every layer of modern software, from frontend interfaces to backend systems.
While many developers specialize in one area, I've always been drawn to the full stack. I enjoy thinking through product flows, designing clean APIs, building intuitive UIs, and delivering features that make a real impact.
Outside of coding, I enjoy sharing what I know. As a web development instructor, I love talking about JavaScript, the web, and the craft of software engineering. I'm currently diving deeper into Go and working towards getting my GCP and AWS certifications.

My Approach
I believe in building software that's not just functional, but delightful to use. Every project starts with understanding the user's needs and ends with a solution that exceeds expectations.

03.Some Things I've Built
Every project here means something to me. They're not just things I've built or worked on, they're late nights, problems solved, hours of trying and iterating... and, of course, moments of joy in the process. That's why I've given each project its own space, not just to show what it does, but to tell the story behind it. The wins, the hard lessons, the creative detours, it's all part of the journey and process that makes this worth doing. These aren't just portfolio items. They're parts of me.
