Myself is a trainer in different computer science subjects. I had delivered more than 3000 students in different computer science subjects like DBMS, Oracle SQL/PLSQL, DBA, PostgreSQL DBA, NoSQL MongoDB, Cloud Computing AWS, Linux Admin and shell scripting and many more. I had my own presentation slides which explains the software in a very clear manner. I explain every thing in step by step with real life example and immediately I provide assignments to the student, so they can be confident to those subjects which I teach. I had done MCA (Master in Computer Application) which is a postgraduate degree in computer application. I also provide guidance to the M TECH students for their projects.
