We were lucky to hire Vlad's services for a day to evaluate the Hibernate data layer of our open source jBilling fork. Vlad had provided effort estimates in advance and a detailed feedback was provided by the end of scheduled day exactly as planned.
The feedback was quite to the point, thorough in terms of domain objects and relationships, prioritized along with explanations. Vlad also allowed an opportunity to seek clarifications later on, which were promptly provided and greatly accelerated the adoption process of these changes in the development pipeline.
We are very happy with the value we received from consulting with you, Vlad!.
