I'm Christian Choi Po Hung, a passionate Full Stack Developer based in Hong Kong. With over 7 years of experience in web and application development, I specialize in creating innovative and scalable technical solutions that drive digital transformation for businesses across various industries.
Throughout my career, I've had the privilege of working with leading organizations including SEEK, Viu (PCCW), EY, and various startups. My expertise spans across modern web technologies, cloud infrastructure, and enterprise application development. I'm particularly skilled in React, TypeScript, Node.js, AWS, and microservices architecture, enabling me to deliver end-to-end solutions that meet complex business requirements.
I'm currently pursuing my MBA at The Chinese University of Hong Kong while continuously expanding my technical skills. I'm passionate about leveraging technology to solve real-world problems and believe in writing clean, maintainable code that stands the test of time. When I'm not coding, I enjoy exploring new technologies, contributing to open-source projects, and mentoring junior developers.
