      Software Development Review from Jake Mackay

      For quite a long time we took orders by e-mail or personally from customers. It took a lot of time, as we either made layouts by hand or printed them according to the vague requirements of clients. All these difficulties have pushed us to take a step towards the digital transformation of our business. The team of Five Jars has developed a frontend and backend for our web tool to create print layouts. The team is not afraid to take on difficult tasks!

      Responsive Review from Anthony North

      I was looking for companies that had experience with large educational platforms. There are some really big players in the eLearning market in Five Jars' portfolio, so I trusted their development experience. After all our platform has become more attractive to users. Over the past year, we have noticed a significant increase in daily visits, so much so that we even had to change hosting. Five Jars helped us with that too!

      Small Business Review from Colin Knox

      I'm satisfied with the MVP we've done with the Five Jars team. I am currently looking for an investor for this project. I love working with professionals when I don't have to dive into a whole area that I don't know. Working with the Five Jars was a real partnership where the other side fulfilled their obligations without my constant checks.

      Software Development Review from Jonathan Gessert

      We partnered with Orases to develop and maintain a multi-tenant workflow management system and customer portal, tailored to streamline our customers and internal team's creation processes. Our previous systems used dated technologies, but Orases stepped in with a PHP and React solution that transformed how we plan, write, edit, review, and publish content at substantial scale. The system now fully supports our end-to-end workflow, allowing for seamless collaboration across teams while significantly improving overall efficiency.Orases exceeded our expectations by delivering a demo in just six months, with the full application live within eight months. Their attention to detail, consistent communication, and ability to stay on schedule were remarkable throughout the project. Their project management approach was highly effective, ensuring that every stage of development was completed with precision and aligned with our needs.The results have been outstanding. The new system has enabled us to increase productivity, handle more complex projects, and reduce the time spent in content quality assurance and client feedback loops. This has directly contributed to our companys growth and enhanced our ability to scale operations efficiently.What stood out most was Orases's methodical and thoughtful approach. They took the time to deeply understand our goals and delivered a solution that met both our immediate needs and long-term business objectives. Their commitment to excellence and alignment with our vision truly made a difference.Working with Orases has been an incredible experience, and their ability to provide innovative solutions, paired with their outstanding teamwork, has been a major asset. We look forward to continued collaborations with their talented team.

      Nema Semnani's Review Sourced from Google

      I'm way overdue in leaving this review. The team at Orases are the best in the biz when it comes to all aspects of app/software development, especially AI software dev. They've been instrumental in helping guide us through the ever-changing landscape of AI, since it definitely feels like if we blink, what we thought was cutting-edge in AI, becomes "old news." Orases helps us stay ahead of the curve...plus on a personal level, they're a genuine joy to work with. Highly recommend!
