Matteo Cargnelutti contributed to the harvard-lil/website-static repository by updating branding assets for the Lewis Center website. He added two new image files, lewis-center-web.jpg and lewis-center-careers.jpg, to the project’s static assets, focusing on enhancing the site’s visual identity without modifying application code. Matteo utilized Git for version control and asset management, ensuring the new visuals were properly prepared for deployment. While the work did not involve changes to JavaScript or HTML, it required careful handling of static resources to support marketing and branding objectives. The scope was limited to asset integration, reflecting a focused and straightforward engineering contribution.
