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.

Infograins Reviews & Testimonials

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

AI Development Review from Steve Melink

CodingCops Reviews & Testimonials
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.

Carie Ageneau's Review Sourced from Google
What a fantastic experience working with DreamCo Design! Jay was incredibly professional and helpful. We got started right away on building my website for a book I hope to see published. Sarah worked diligently on the design and included me in every step, explaining things thoroughly and communicating in a timely manner. The price was reasonable and well worth it for the product I received. I couldn't be more thrilled with their beautiful work! Even after the process was completed, they have maintained communication and check in to see how things are going. I would absolutely recommend DreamCo Design if you are seeking a wonderfully crafted website, tailored to your specific interests by a talented team of people.
Moshe Turk's Review Sourced from Google
We randomly found DreamCo Design online. It was actually their design style and energy that first caught our eye, but creative design is just the beginning. Their professionalism, client interaction, and execution are the real trademarks of this firm, and what makes us love working with them. DreamCo Design has done multiple projects for us over the years, and we absolutely love working with Jay and his team.
Chris's Review Sourced from Google
We contacted Jay and his team to design a website as well as a theme around our company logo. We are new and so it was a ground up project. The team at DreamCo design delivered what was asked and the site has been up and running since! Real person, real review. Chris; managing partner with Poseidon Charters Inc in Turks and Caicos.
