I Will Code It
Reviewed on 9/7/2025
I had the pleasure of collaborating with Benjamin again, who joined our team for a SaaS project in Next.js, Supabase with an integrated test suite. Benjamin proved to be autonomous and demonstrated effective communication for the team. His work resulted in an excellent first draft, in line with our development patterns. His knowledge of the AWS stack was also welcome in dealing with the minor unforeseen issues of such a project.
Let's do it again together ASAP!
