Hi, I’m Changdae Jung M, a software developer with a strong focus on backend and full-stack development. I have over a decade of experience across backend and frontend work, using Python, Django, React, JavaScript, TypeScript, and Java, plus databases and cloud technologies. I’ve built APIs, data pipelines, and user-facing interfaces, delivering robust, scalable solutions and collaborating effectively with cross-functional teams. I value clear communication, practical planning, and delivering high-quality software on time. I enjoy turning complex requirements into maintainable code, balancing big‑picture architecture with hands-on implementation, and continually learning to keep up with new tools and best practices.
