I had almost given up on getting mentoring support regarding data engineering career until I met Shashwath. Out of so many tools and technologies to learn from which is confusing, he gave me a very clear roadmap to follow by starting from basics and then moving up the ladder to specific tools and technologies and avoiding the unnecessary parts which can be learned later. I can't thank him enough for his expert suggestion which is helping me big time and his friendly and cooperative attitude towards a mentee!
