Hi, I’m Ricky — a passionate Frontend Engineer who loves crafting intuitive, performant, and visually engaging web experiences. I specialize in JavaScript, TypeScript, and modern frameworks like React.js (Next.js, Vite) and Vue.js (Nuxt.js). Over the years, I’ve built scalable platforms, high-performance form-driven applications, and seamless WebView-based solutions that bridge the gap between web and mobile. I’m also experienced in optimizing websites with Static Site Generation (SSG) and Incremental Static Regeneration (ISR) to achieve lightning-fast performance and SEO-friendly architecture.
I’ve worked on projects in the banking, finance, and investment sectors, developing secure, data-rich platforms that prioritize stability and user trust. I care deeply about clean architecture, performance, and maintainability — using tools like Node.js, Firebase, Turborepo, and Git to create efficient, scalable development workflows.
Outside of work, I’m often experimenting in the kitchen, exploring new recipes, or making a perfect cup of coffee to recharge. I love listening to jazz and swing, relaxing with video games, and learning Japanese — hoping to visit Japan someday to experience the culture firsthand. For me, great engineering is a lot like cooking or music — it’s about creativity, balance, and finding harmony between all the moving parts.
