My background and journey

About Me

I am a passionate Fullstack Developer with a strong foundation in Computer Engineering from Hanoi University of Science and Technology (HUST). Over the past years, I have built web architectures using Next.js and NestJS, optimizing enterprise systems and high-traffic public platforms.

My core focus is delivering user-centric digital solutions with high performance and seamless UI/UX. Recently, I have actively integrated AI/LLM solutions to automate complex data workflows, content generation, and intelligent reporting.

With a strong problem-solving mindset and cross-functional team experience in Agile environments, I thrive on translating business challenges into clean, scalable, and secure software components.
