Karthikeyan A K
Ruby Jedi. Coding in Ruby on Rails for 15+ years
About
I am a Ruby on Rails professional who has been coding on this platform for the past 15+ years. I have been coding since Rails 2.x. I have been involved in massive Ruby on Rails projects that had nearly 0.3 million lines of code. I have managed teams where we took projects which had almost no test coverage to 90%+ test coverage.
I have experience working with massively scaled apps, monitoring logs for anomalies, and fixing them immediately. My verticals include Finance, Health, E-Commerce, Social Networks and more.
I can port apps from one Rails version to another and migrate Ruby versions. I can work as a solo high-impact developer, or I can set up and manage a team for you.
Recently as a freelancer, I have consulted with some companies on Prompt Engineering as a part-time job while developing an investment platform for my friend's firm.
