Front-end Developer @ Cape

I am pleased to recommend Jason for any frontend development role. During his time at Cape, he was of great value to our team. He worked on implementing the ability to edit and display SVGs.

Jason consistently wrote clean, high-quality code in TypeScript, demonstrating strong problem-solving skills and proved his ability to overcome technical challenges.

Jason was a great team member in both professional and social settings. He collaborated well with colleagues, maintained a positive attitude, and showed interest in learning new things.

Portfolio Website v2
A personal website designed and developed to showcase my professional work, skills, and background. Built using NextJS, React and Tailwind, the site emphasizes clean design, smooth navigation, and responsive performance across devices. This project reflects both my front-end development abilities and attention to user experience, while serving as a living document of my ongoing growth and creative work.
SVG Editor in Template Designer
Integrated a new feature for Template Designer, where now users can use and customize SVGs. This feature allows customizations such as colour and shape customization. Shape customization works by the user drag dots around the SVG and its shape will follow based on the interaction.
