About Me

Hello, World! I am Duy, a Mid-level Frontend Developer with 3.5+ years of experience building high-performance web applications. Proven track record of driving business growth, including a ~300% revenue increase (from $300K to $1M/month) by spearheading a successful migration from legacy PHP to Next.js.

Expert in Monorepo and Micro-frontend architectures, performance optimization, and secure payment integration at scale. Skilled in hybrid rendering (SSR, ISR), Core Web Vitals, and pixel-perfect, responsive interfaces for high-traffic platforms.

Experienced in creating smooth animations with GSAP, real-time features (WebSockets, live notifications), and payment gateways (Stripe, Airwallex) with PCI DSS and 3D-Secure compliance. Strong collaborator with Marketing on GTM, SEO metadata, and legal compliance (Cookie Consent, RDP) for US and EU markets.
