I am Dhayalan, having 12 plus years of IT experience using ROR and I have done design, development, and support of various web applications. Since I started my career in ROR, till now I worked in almost all the versions starting from Rails 1.2.3 to Rails 5. I had a pretty good experience in Configuring and troubleshooting Rails Production and Staging Servers and migrating User Interfaces. Currently, I work as a Full-time employee and deployed in the client. The work is to upgrade the legacy application (Built-in 2008) from Rails 2.3.3 to a Higher version. Single-handedly I have upgraded the entire application to Rails 3.2-stable. My contract is there on up to June 2021, just to give Knowledge Transfer. Meanwhile, I don't want to be idle, Just wanted to make use of this period to contribute in Freelancing.
