InterTAD - Clients

During the time that I worked with InterTAD, I found that InterTAD possessed a great amount of technical focus and had the ability to come up to speed with the complexities of the code in a very short period of time. Our initiative required engineering support during many nights and weekends, and contractors made themself available to assist with any number of issues, regardless of day or night. InterTAD was able to investigate and resolve issues that required immediate attention and quick turnaround.
The project has been completed. 100% in scope. The product was deployed to production. All of my goals were accomplished. The quality of the work exceeded expectations as well as did the technical skills and ability in performing the tasks of the project. The ability to solve problems and be creative when required also exceeds my expectations.

As the requirements finalized and changed through the project InterTAD was very supportive to changes and accommodating to our needs. InterTAD's support in knowledge transfer to support staff offshore was beyond what should have been to expectation. InterTAD adapted the work schedule to support the resources in India and helped in what should have been labeled training other than KT.

ProseMarket is the pilot project from scratch for the new startup. The budget was quite limited however InterTAD did a great job. Top edge technologies were used on the project. Very good quality and communication. We had a situation at the end of the project when we found out that an important functionality was missed in the original requirements. And InterTAD added several days of the development within the same budget just to make the product completed. It made the founders really happy. Very smart and reliable. Highly recommend to everyone.

I have worked with InterTAD resource for several years, as both a direct and indirect-report manager, and also alongside him on engineering tasks on many occasions. I can say without reservation that he is a very skilled and productive software engineer. He has a deep knowledge of and experience with the Java technologies used in our services .. and is also equally-capable on the front end, often taking on jobs that required him to dive into our website and the code of our many API client applications. He works well given just a general spec for tasks, exploring options for implementation, and then working tenaciously to get to completion. There is more that I can say. Please contact me directly, if you'd like to talk.
