Hi, I'm Patrick
full stack developer
software engineer
web developer
I build web app products that solve real problems. Focused on clean code, great UX, and shipping fast.
John Patrick Ryan Mandal
I obsess over the details. Writing clean code, building products that actually matter, and paying attention to the small things others overlook.
I got into coding through video games as a kid, fueled by a curiosity to understand how things worked under the hood. That curiosity grew into a career—backed by a Computer Engineering degree and 2.5 years of professional web development experience. Today, I focus on building clean, scalable, and user-centered applications that solve real-world problems and deliver meaningful impact.
TypeScript and React are my comfort zone, but I'm not married to any stack. Good engineering means choosing what fits the problem, not defending your favorite framework.
Based in Cebu, Philippines.
