Software Development Review from Marcos Queiroz
They were very responsive and the quality of the work was good. We experienced a few challenges with the back and forth during deliveries and some unexpected delays but they were always receptive to feedback and responded well to our concerns. I'd happily recommend them, especially Megha as the Project Manager and Savan as the Developer.

kathi Richard's Review Sourced from Google
We had this cool idea to create adaptive learning paths for our students based on their quiz performance and interaction patterns. But building the logic was beyond our team’s expertise. CodingCops helped us hire AI developers who designed a lightweight recommendation model that personalized learning modules dynamically. It made our platform way more engaging for students.
Ashley Kai's Review Sourced from Google
CodingCops has some of the best engineers out there. We brought on a QA Automation Engineer through them, and he turned out to be the best we’ve worked with after trying several contractors before. Super skilled, technically sharp, and he really took ownership of QA. He felt like part of our team from day one, not an outsider. We’ll definitely be going back to CodingCops again, not just for this role but for others too.
Rachel Willy's Review Sourced from Google
They’ve done an excellent job connecting me with a skilled developer. They’ve also been very responsive in addressing any issues along the way. I’m extremely satisfied with both the service CodingCops provides and the developer I’ve had the chance to work with.
