About
Hi! I'm John Adrian Ticatic, a Software Engineer based in Batangas, Philippines, with 2+ years of experience. I build both web and desktop applications, primarily using React, Next.js, and Node.js for the web, and .NET for desktop systems. I'm passionate about clean code, intuitive user experience, and solving real-world problems through technology. Currently, I work at Newborn Screening Center - Southern Luzon, where I build internal tools, dashboards, and desktop systems that help teams work more efficiently.
