Sirasith Ruengsilapavilai
Application Developer at IBM
I'm a full-time application developer who spends most of the day in the DevOps lane: pipelines, containers, and the dashboards that tell you when something breaks.
My name is Game, Nice to meet you! :)
I like the unglamorous work that makes a release boring, in the good way.
