About
I am a senior frontend engineer and Chief Technology Officer at PaluDevHouse. I have professional experience since 2022 building web and mobile applications with React, Next.js, React Native, TypeScript, React Query, React Hook Form, and Expo.
My work has expanded from implementation into frontend architecture, performance optimization, code review, mentoring, stakeholder communication, and technical leadership for a six-member project team. I also hold a Bachelor’s Degree in Computer Science with a GPA of 3.72 / 4.00.
I am preparing for master’s study in Artificial Intelligence or Cybersecurity. My goal is to connect production engineering with responsible AI adoption and trustworthy software systems without overstating experience that is still developing.

I am preparing applications to the National University of Singapore, Nanyang Technological University Singapore, and National Taiwan University. Artificial Intelligence and Cybersecurity are intended areas of study—not claims of current professional specialization.
Artificial Intelligence
I want to study intelligent systems beyond surface-level API use: evaluation, human oversight, privacy, reliability, cost, latency, and responsible deployment in real products.
