About
Thanks for stopping by! Here's a bit about me.
Hello 👋, I'm Hai Trinh (Ethan Nguyen), a Software Engineer | Frontend Engineer | Backend Engineer based in Ho Chi Minh City 🇻🇳. I specialize in building scalable and clean UI systems using React.js, Next.js, TypeScript and more .
Over the past 3+ years, I've worked across industries from trading, beauty, banking systems, to IoT platforms. My experience spans both startups and enterprises where I've led UI architecture, optimized performance, mentored junior developers, and collaborated closely with product and backend teams.
My stack includes modern tooling like Redux Toolkit, TanStack Query, Vite, Rsbuild, Rspack, CI CD Pipeline ,and Docker. I believe in writing clean, maintainable code, ensuring pixel-perfect UI, and delivering delightful UX.
Outside of coding, you'll find me debugging layout bugs with a coffee ☕ in hand, learning new technologies 🧠, and working out at the gym 💪.
