All things considered, they offered outstanding support and a dependable app that improved our clientele's experience.

Software Development Review from Grzegorz Grabczak
We worked with Zealous System on an AI-powered fraud triage solution for one of our clients in the Europe financial services sector. The project involved a complex fraud investigation workflow where analysts were handling a large number of alerts and gathering information from multiple systems. Zealous System worked closely with us to understand the requirements, existing processes and expectations of the end client before moving into development. The team developed an AI-powered fraud triage agent that brings relevant information together, helps prioritise alerts and provides explainable recommendations while keeping human analysts involved in important decisions. What I appreciated was the team's ability to understand both the business and technical sides of the project. Communication was consistent, and they were responsive when requirements evolved during development and testing. The solution helped streamline the investigation process and reduce the amount of repetitive manual work involved in reviewing fraud alerts. Overall, we had a positive experience working with Zealous System. They were a reliable technology partner for us on this project, particularly given the complexity of introducing AI into a financial services environment.
DIPAK VAIDH's Review Sourced from Google
I visited Zealous System on 16th June 2025 for the walk-in interview announced on LinkedIn for interns/freshers in Python, PHP, WordPress, .Net, and QA roles. Despite clearly stating it was open for freshers, upon arrival, all Python candidates, including myself and my sister, were told they only accept those with prior experience, as interns are directly placed on live projects. This information was never mentioned in the post. The company blamed the marketing team for the misleading post. This experience wasted our valuable time, energy, and travel expenses. I urge the company to coordinate better internally and post accurate job/internship information to avoid misguiding freshers who genuinely seek opportunities.
Ravi Prajapati's Review Sourced from Google
Zealous System is outstanding when it comes to AI development! Their team helped us build a smart, AI-powered software solution that completely transformed how we manage data and customer interactions. They explained complex AI concepts in simple terms and delivered a solution that works flawlessly. From planning to post-launch support, everything was smooth and professional. Highly recommended if you're looking for reliable AI experts!

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.

Working with Miguel at Unique Web Designer was a very pleasant and professional experience. He delivered on time, and exactly what I requested. He took the time to understand my vision and my brand. He went above and beyond by making sure that I knew how to make future updates (such as adding additional products) to my website. He was courteous, diligent, and demonstrated skill and expertise throughout the project. The fact that he is fluent in both English and Spanish was an added bonus. I would work with him again and highly recommend his services.
