In a word... Rajvir is "Awesome!" I had the pleaser of working with Raj over the past 1-2 years on various social media projects including YouTube videos on the Code and Compile platform to a Podcast. Raj is very professional and truly knows his stuff. What started as a business relationship has morphed into a friendship. Thanks for being great Raj!

Dave Eifert

International Man of Mr. IIoT
I had seen Rajvir's YouTube series on PLCnext Control. He did a very thorough job of touching on and demonstrating many of the capabilities of this controller. I reached out to Raj via LinkedIn, He INSTANTLY answered back, and asked if he could get on line with me via TeamViewer and showed me how to correct my problem! EXCELLENT KNOWLEDGE, SURPASSED ONLY BY SUPERIOR CUSTOMER SERVICE!! Most highly recommended!

Working with Rajvir to develop a series of educational videos for our product was overall a great experience. Rajvir is professional, kind, and a great communicator. The content that Rajvir developed was exceptional, and beyond our expectations. The content was organized in an intuitive and easy to understand manner. I highly recommend Rajvir to anyone in this industry, and we look forward to working with him again soon.
