Front-end developer intern
2024 - 2025
During my internship, I worked on enhancing the template creation experience by introducing SVG support, allowing users to incorporate scalable vector graphics into their templates. I implemented features enabling users to import SVGs or use predefined SVG shape templates, providing greater flexibility in design. Additionally, I developed customization options, allowing users to modify attributes such as size, stroke, fill, and color. To further enhance user control, I added functionality to manipulate SVG shapes by adjusting coordinates or adding new points. Lastly, I ensured that SVGs maintained dynamic sizing within templates, optimizing rendering performance by adhering to minimal height and width constraints when storing data.
