Background & Focus
Early-career developer passionate about software engineering fundamentals, full-stack web applications, and building reliable systems.
I am a Computer Science student at the Royal University of Phnom Penh (RUPP) and an active trainee in the intensive IT Expert program at ISTAD in Phnom Penh, Cambodia. My primary interest lies in full-stack web development—building practical tools where intuitive user interfaces connect seamlessly with reliable backend services.
On the frontend, I focus on building responsive, maintainable user interfaces with React and Next.js. On the backend, I engineer robust RESTful APIs using Java and Spring Boot, managing structured data with PostgreSQL.
I approach software with a strong focus on problem-solving, continuous learning, and clean code principles. Working on projects such as the Mart System POS, Khmer Service Marketplace, and the DevSolve team collaboration has given me hands-on experience designing schemas, preventing race conditions, integrating payment gateways, and collaborating across multidisciplinary teams.
I am eager to contribute my energy, adaptability, and technical foundations to a collaborative engineering team as a Junior Full-Stack Developer or Software Developer Intern.
Frontend Interfaces
Crafting responsive, accessible web interfaces using React and Next.js with type-safe contracts and smooth client-side interactions.
Backend REST APIs
Designing clean Controller-Service-Repository architectures in Java and Spring Boot with PostgreSQL and secure JWT authorization.
Problem Solving & Teamwork
Collaborating effectively through clear API contracts, Git feature-branch workflows, and pragmatic debugging of complex business logic.
