During the "green-field" development of a SaaS based software I had the pleasure to work directly with Sujit as Project Manager. From beginning of the project Sujit with his team understood properly the objectives of the software to be developed. We've run regular meetings to cover project status and clarify any doubts before releasing the beta version. Applying this approach we've anticipated any type of last minute surprises which might have negatively impacted the project. The project was executed within expected timing and budgets. Sujit and his team demonstrated beside huge software programing expertise also flexibility and customer oriented approach. After the initial development of the SaaS software, we've been requested by our customers to amend new features, therefore we've conducted further developments with Sujit and his team. I strongly recommend Sujit due to his strong IT development expertise, business process acumen and personal kindness. Great business partner to work with.
