I am Vishnu VN, a DevSecOps engineer from Kerala, currently employed at Epixel Solutions Pvt Ltd. I possess extensive knowledge of major cloud service providers. Prior to this role, I served as a System Administrator in Mumbai. My educational background includes a B-Tech degree in Electronics and Communication Engineering. On a daily basis, I successfully resolve numerous IT-related issues. My primary focus lies in containerization, virtualization, and automation, as well as managing hardware, software, and network-related concerns. Furthermore, I have gained significant experience in operating systems, Citrix, and network fields. Additionally, I have completed the VMWARE data center virtualization course and obtained certifications in Fortinet NSE-1 and NSE-2 courses.

During my past years of experience, I found that many people struggle with their limited technical knowledge. In most cases, the problems are not issues. lack of knowledge in technology that makes them panic. These unwanted issues kill a lot of time for both the It team and the employees.

So I have decided to create a website and share my experience with others. I purchased a domain with my name, Vishnu VN. This website discusses the issues related to Windows, Linux operating systems, and DevOps operating tools. I have tried to make simple presentations for all topics. Hope everyone will help with these lessons.
