      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.

      Software Development Review from Jeremy Ott

      This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

      eCommerce Development Review from Luc Vlekken

      We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

      Software Development Review from Dan Adika

      Infograins has helped us develop our custom software system. Before we signed the contract, we had initial pre-sales meetings, during which I provided them with documentation. We also signed an NDA so that they could look at everything I provided. Then, Infograins came back with an in-depth project proposal of about 50 pages and we signed the contract. As for the technology stack, we're using React.js, Python, and Django to create this software piece. Moreover, our whole backend is hosted in AWS. We're very happy and satisfied with how everything has turned out and with the whole Infograins team. Their willingness to discuss issues, fix problems, and help us with anything we need is great, so I wouldn't want to have developed this product, especially the MVP with anyone else. I can't think of anything Infograins could change. Going forward with other projects, we might find some improvements. Thus far, we're very happy with them

      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.

      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.
