SapientPro Reviews & Testimonials

Software Development Review from Slava Berkovich
SapientPro consistently delivers high-quality work that aligns with project requirements. The team demonstrates strong expertise in Angular, TypeScript, and JavaScript. Their project management and communication practices are highly effective, with weekly client meetings held to provide updates on progress and ensure alignment.

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.

Qualimatrix Technologies Pvt Ltd Reviews & Testimonials

Web Design Review from Stephen Peal
Qualimatrix Technologies team designed our logo. First, we asked them to provide us with various logo options ranging from hyper-conservative to ultra-modern. Then, they created four templates, two were more straightforward, and two were more modern with bold colors. Once we chose the template that spoke to us most as an organization, we chose a font, and Qualimatrix Technologies managed the final logo design process from beginning to end.After delivering the final logo, they built our website from scratch using a WordPress template. The website is our digital factory and lead generation tool for customers to engage with us online. The team also helped us with keyword research and provided website SEO and copywriting services. We collaborated with them on different pages to ensure they contained the right keywords for Google and Bing. We host the website internally, but they occasionally help with maintenance requests.The website functions very well, and were pleased with the core site vitals. Since were still getting indexed, its too early to see the results of our website traffic. However, were heading in the right direction, and the site has received positive internal feedback regarding its design. We've been tracking our keywords and have climbed to the first page of the search results for some of them. We've also run technical SEO audits that have garnered positive results.

Software Testing Review from Isobel - Rose Bailey
The project resulted in:Bug Reduction: A significant decrease in identified bugs, enhancing the user experience.Improved Performance: Positive feedback regarding the platform's speed and responsiveness.Enhanced Security: Successful identification and mitigation of potential security risks.Qualimatrix Technologies demonstrated commendable project management. They consistently delivered items on time, and their response to our needs was prompt and effective. Regular status updates and transparent communication ensured a smooth collaboration.

Software Testing Review from Itamar Lesuisse
The manual testing has provided confidence that our application is stable and functioning. The amount of progress we have made with automation testing has been incredible. We use a custom CLI that the team has been able to get accustomed to and we can now run hundreds of automated tests before deploying. Communication has been sufficiently managed over Zoom and Slack. We have a weekly standup at the start of the week and have plenty of dialog over Slack throughout the week. The team sends end of day and end of week summaries which are great to understand and track progress and the team was very quick to onboard and begin testing. They have been incredibly thorough and have proved to be an invaluable part of the QA process.
