      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 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.

      I had been actively searching for new job opportunities for over three months, often finding that many promising postings were either already filled or closed to applications within 24 to 48 hours of being posted. It was a truly frustrating experience. However, with the invaluable assistance from dotLinkers, everything changed. They were instrumental in helping me establish direct contact with the recruitment team at my future employer. The entire process was incredibly straightforward, and what truly set them apart was their exceptional communication. I was consistently informed about all requirements and received regular, timely updates on the status of my application throughout the entire recruitment journey. This level of care and transparency made a significant difference, turning a previously daunting search into a successful and well-supported experience. I highly recommend dotLinkers for their dedicated support and seamless process.
