About

Hey! I'm Neo, a recent Computer Engineering graduate from Chulalongkorn University and a Full-stack Developer who genuinely loves building things that work well and solve real problems. My roots are in competitive programming—I'm a TOI gold medalist and represented Chula at the ICPC Asia Regional. That background gave me a deep appreciation for algorithms, optimization, and writing clean, efficient code. When it comes to building products, I don't just write code—I take full ownership. As the PM and sole developer behind projects like One Night Miracle, I handle everything end-to-end: scoping features, designing in Figma, building the frontend & backend, and wiring up payments and infrastructure. Definitely not about blind 'vibe coding' or pasting AI output without thinking; I care about understanding the system, intentional architecture, and building software that actually holds up in production.
