I just want to say that it was really enjoyable working with you … you brought very strong professional skills. In addition to rather stunning results we have achieved (300%) w/o adding more H/W … All goals set by me in the beginning of this session were completely achieved and even beyond!

us in front our top accounts and in our most demanding engagements.
We had to completely replace the underlying database of a very complex product, there were many technologies involved, there was no one was familiar with the code, no one knew the database schema, there were plenty of massive performance bottlenecks and there(...)
was a harsh time limit… Within short time since 1 2 3 completed joined, we learned the system, we coped with all technological challenges, we cleared all other obstacles, and we have got a living example of professional standards that were the key factor to this project success. … For me it is crystal clear: without 1 2 3 completed on board, we would never complete this project in quality on time. Thanks for making this happen!
The relationship between Oracle and 1 2 3 Completed experts has proven itself for over 15 years now. We are happy to place any projects in their safe hands.

Pontis is a pioneer of real-time, segment-of-one marketing and customer base management solutions for Communication Service Providers. 123Complete recently worked with Pontis on developing one of Pontis' newest technologies. This was a technological challenge,(...)
and despite short time frames the project was successfully completed and transferred for production tests. Our partners from 123Completed were essential for the project. They showed dedication and innovation, brought with them wealth of experience and acted as an integral part of the Pontis team. It was a pleasure to work with the 123Complete partners.
Without your great help, I am sure the project we had would have never been finished on time … Your knowledge and capabilities about databases is very significant and was crucial for the success of our project.
We are not afraid of any challenge and we have the references to prove it.
