What I'm looking for

I’m looking for a full-time product environment where I can deepen PERN stack expertise, keep shipping scalable features, and collaborate closely with a team that values performance, testing/debugging rigor, and real-world impact.

I’m a Full-Stack Developer with hands-on experience building web and mobile applications across e-commerce, loyalty, and AI-powered platforms. I’m strongest in React/NextJS, Node.js/NestJS, PostgreSQL, JavaScript, and HTML/CSS, and I focus on shipping scalable features in collaborative teams.

As a freelance e-commerce and campaign developer, I’ve implemented core storefront and admin workflows (catalog, variants, cart & checkout, vouchers, dashboards) and designed API architecture and caching strategies for scalability. I’ve also built high-performance landing pages and CMS dashboards, integrating SEO/social metadata optimization and analytics-friendly backend services.

From building a Zalo Mini App for loyalty programs to supporting enterprise admin systems and reliability improvements during internships, I’ve consistently optimized performance, debugging, and system stability. I’m now ready to deepen PERN stack expertise in a full-time product environment and keep delivering measurable impact.
