I'm Callum Sullivan, a passionate and driven full-stack developer based in Dunedin, New Zealand, originally from Whangarei. I completed my Bachelor of Science degree, majoring in Computer Science at the University of Otago in 2024, with my official graduation in May 2025. Over the past three years, I have gained extensive experience in academic software development, working with a variety of programming languages and tools, including Java, JavaScript, Python, SQL, Node.js, and Express.js, as well as tools like Git, Docker, and MySQL. Outside of coding, I enjoy staying active through scuba diving, snowboarding, and exploring the outdoors, which have taught me valuable skills like adaptability, problem-solving, and teamwork. I am excited to continue growing as a developer and contributing to innovative projects that make a difference—feel free to explore my portfolio or reach out to connect!
