What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a Senior Frontend Engineer with over 10 years of experience in building high-performance, accessible, and scalable web and mobile applications across various sectors including fintech, healthcare, e-commerce, and logistics. My expertise lies in React, Vue, and Angular, with a strong focus on microfrontend architecture and cross-platform development. I thrive on mentoring teams, optimizing user experiences, and ensuring that technical execution aligns with business goals.

In my current role at Bank of Singapore, I designed and implemented a microfrontend architecture using React, Next.js, and TypeScript, which improved page load speed by 40%. I also drove WCAG 2.1 AA compliance and optimized UI responsiveness, achieving consistent 95+ Lighthouse scores. My previous experiences include building modular UI components for IoT diagnostics at Robert Bosch and leading SPA development with Vue.js at Uncharted, where I significantly improved SEO and user retention.
