TechAvidus Reviews & Testimonials

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 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

Mobile App Development Review from Ben Mark
We were encountering a multitude of problems with our Equalizer - Bass Booster & Volume Booster app, from persistent background running issues to optimization and compatibility concerns. So we decided to hire RisingMax's team to tackle these issues head-on.The results were nothing short of impressive. The compatibility issues that had been plaguing us for months were swiftly addressed, and the end product was nothing short of amazing. Our app now runs smoothly and efficiently.

Healthcare Review from Mark Cabrera
RisingMax Inc.'s entire staff is supportive. They provide their customers with high-quality services and care about them. They take on tasks with a sense of responsibility, work hard, and meet deadlines. During the consultation, there was a constructive discussion. The project manager was taking notes and providing further suggestions while the developers pooled their resources to create any helpful software, which I thought was fantastic. I appreciated the initiative.

Web Development Review from Dawson Thomas
