I would like to thank the Thetaone team for their excellent work on the data quality dashboard project.
Throughout the engagement Tamal, Sibu and Debajyoti were sensitive to the project goals, they came up with innovative workarounds for those tricky requirements. If there were issues with the deliverable, they are extremely quick to rectify the problem.

The team is extremely hard working and always go the extra mile, even work across multiple timezone to get the project across the finish line. In the end we have developed a high quality product that I am extremely proud of.

I am sure we will partner up with Thetaone on many more projects in the future.

Tamal and his team from Theta One helped me carry out my first chatbot-related project. They put a lot of effort in trying to understand my needs and came up with an efficient and cost-saving architecture. 
Tamal and his team kept me up to date on the project at any time and provided all the information I needed to take relevant decisions.
I am very satisfied with the final outcome and look forward to working with Theta One again in the future.

Thanks so much for the cost effective solution. About 100 municipalities of West Bengal are being benefited from the solution.
