"Mayank was an utmost professional. If you are looking for a knowledgeable, patient, and professional mentor....look no further. Mayank was great at helping me resolve a very obscure AWS issue having to do with SSH/SFTP connectivity after one of our servers died. It may sound easy, but it was a time-consuming, digging expedition. All the usual checks were done but Mayank took the time to look beyond that and successfully resolved the issue. THANK YOU!!! If I ever run into another brain-teaser like this problem, I know Mayank is the one that can help. Highly recommend him."
