Developer Needed for Proof of Concept (POC)
Yasir conducted himself professionally throughout the project, and the work completed met expectations. While we encountered some hiccups that led to scope changes and extended timelines, both parties reached a mutual agreement to pause and resume work in the future. I would recommend Yasir and his team.
