01.About Me
Hi, I'm Kelvin, a software engineer passionate about building efficient, end-to-end applications. Ever since creating my first web project back in 2020, I've been driven by curiosity to understand how everything fits together, from frontend interfaces to backend systems. Five years later, that curiosity is just as genuine as ever.
I've always believed that anything worth doing is worth doing well, and I see that in software too. I'm a little obsessed with how systems fit together, the design, the flow, the small details that make big differences. I care deeply about system design and the thought that goes into how products work, how each layer connects to create something reliable and cohesive. Whether it's designing APIs or creating UIs, my main goal is building software you can trust, the kind you can sleep well at night knowing it's working just fine.
Recently, I've been building software that not only meets those standards but also drives real business results. Products that generate revenue, improve efficiency, and create measurable impact. Seeing good engineering translate into growth and value for the people who use it is one of the reasons I love building software.
Right now, I'm working on my startup, SchoolNexus360, and spending time learning Go and advanced system design.
