As a team member redesigning my photography website, Sebastian demonstrated above-average capability in all aspects of the project including design, coding, and CMS tools, utilizing various tools, including Figma, GitHub, and Sanity CMS. When we navigated some early changes in the design direction, he took the initiative and created some page skeletons using Figma, set up a Github repository, and introduced the Sanity Content Management System to effectively lead the team to a successful completion. I would highly recommend Sebastian to others facing similar challenges.

Learner feedback
The team of four that I selected successfully achieved the project goal of creating a modern, visually appealing, and user-friendly website. The project involved redesigning the website's layout and integrating a content management system (CMS). The team communicated with me on a weekly basis, both collectively and individually. Using Figma, they created a multi-page design for the new website and then divided the 16 pages among themselves to code. Although I’m not a coder, they effectively guided me through the process, explaining things in layman’s terms while also engaging in deeper discussions about the design, coding, and CMS tools they used. I had requested the ability to edit the website’s content in the future, and they ensured this functionality was included. I was very impressed with how the team maintained a consistent design, carefully selected the best tools for the project, effectively divided the workload, and successfully combined their efforts to deliver the final product. Sebastian stands out for taking the initiative and creating some page skeletons using Figma, then setting up a Github repository, which all of the team used to code each of their pages. He also introduced the Sanity Content Management System (CMS), which gives me (the client) a user-friendly interface to work with whenever I need to edit the content of my website.
