My acquaintance works for a company specialized in processing flight data in real time. I'm not certain about the detail, but apparently, the common backend solutions like Java, Node, Ruby etc. are not sufficient. In the end, they built everything using C. You heard it right, the backend was built with C, that was mind-blowing to me. 😲
With that said, what was the most exotic codebase you had ever worked on? What led you and your team to the decision? How was your experience with that solution?
