    Customer Feedback


    Our cooperation with Jellyfish has been outstanding since before initiation of the contract for developing the system. They initially suggested changes in technology choices for the system that has saved substantial investments for the project, made it more robust, and made sure the system is user-friendly. Throughout working with them, they have shown flexibility, a genuine interest in our project, come up with exceptional solutions to problems that were impossible to guess in advance. They have humor; they are down to earth; they are listeners; they are hungry, and they are true professionals in all senses.

    The team was a great find, they have been brilliant in turning our concepts into reality. We visually design the concepts in wireframes and the team is always able to turn that into code and deliver. This has helped to broaden our thinking and designs to areas we didn’t think possible. We consider to be part of our virtual team, and enjoy working with the assigned PM who is diligent and pragmatic.

    NDA delivered a strong, functional app. They employed an efficient sprint methodology to deliver project elements on a weekly basis. I appreciated the fact that they conveyed constructive criticisms and ideas on how to solve problems in another way than I anticipated. The team contributed valuable insight into the best solution to each challenge. The final solution was delivered on time and on budget.

    Through' technical skills, the partially completed tool has already achieved impressive reliability with robust coding. I just like their honesty; if something is not going to work out or they have a better solution, they always let us know ahead of time. The team’s transparent organization and adherence to the delivery timeline continue to promote efficiency and facilitate trust.
