Vijay and I worked on a number of customer engagements and product features. I enjoyed collaborating with him on all our projects. His can-do attitude and active listening skills made it a memorable journey through all our engagements. When it comes to python based data engineering solutions, Vijay always focused on the feasibility and scalability. I had the opportunity to learn some cool new python tricks from his extensive experience and will always work with him any day. I wish Vijay the very best and would recommend him any day!
