Dexiang Chen

I'm a recent graduate of MSc Computer Science at UCD. I have a keen interest in backend technologies. I am self-motivated and capable of working in high-pressure environments with an intense sense of responsibility, and willing to continuously learn and adapt.

I am working on the full-stack projects involving Java, React, SQL, JavaScript, and HTML/CSS. I implement it for the sake of proof of concept and self-learning. I also gain experience in Machine Learning and data analysis with Python from previous coursework.

I graduated in Dec 2022 and I'm looking for graduate/junior software engineer position where I can leverage my skills for impactful contributions.

Programming Languages: Java, Python (scikit-learn, NumPy), JavaScript, HTML/CSS, SQL, Shell
Frameworks: Spring Boot, React, Bootstrap, Junit, Mockito
Platform/Tools: Docker, Kubernetes, Jenkins, Azure, AWS, Maven, Git, Jira, Axios
