Before 2012

During studying in university, a friend of mine said: β€œIn Ruby language, libraries are named GEMs πŸ’Ž β€” it's so cool.” That's why I start studying Ruby.

During my past work in fintech, I had created high-frequency trading bots for zero-risk futures/options strategy. It makes really high trading volumes on market. Once it was some glitch and it loses all its profit for last several months πŸ˜”. Actually, losses were small. But my friends still joke that my bot makes a whole company bankrupt.

Once I accidentally dropped the production database πŸ’₯. Hopefully, it was at the very beginning, and we have a small number of clients. I restored it from backup. Nobody noticed.

Once I accidentally disabled billing on our primary cloud provider πŸ€¦β€β™‚οΈ. Hundred of production VMs were instantly shutdown. Hopefully, after re-enabling billing, everything was correctly started, and downtime was very short. In my defense, the cloud provider has an extremely bad-designed billing page.
