“I like to travel, explore new places, and create memories. In the same way, I want to explore a system — how it works, and what it does.”
Hi, I'm Hiyan Jong Rai (हियान जोङ राई), a Backend and Full-Stack Developer from Udayapur, Nepal, currently based in Kathmandu.
I'm currently studying Bachelor of Computer Applications (BCA) at Tribhuvan University, Aadim National College.
I mainly work with Java, Spring Boot, REST APIs, MySQL, and PostgreSQL. I enjoy building backend systems, designing databases, and writing clean and maintainable code. I'm also interested in full-stack development and enjoy turning ideas into real, working applications.
Along with development, I've worked on SEO and digital growth for businesses including Delito Kathmandu, Himalayan Hub, and Mirai Design & Print.
I'm always learning and improving my skills through personal projects, practice, and continuous self-study. I enjoy solving problems and building software that is simple, reliable, and useful.
