I have been using it on and off part time for close to six years, and I have led multiple large scale TypeScript app projects, some as tech lead, and some in C-level executive role which exposed me much more to the cost analysis perspective. I do have a lot more to learn about TypeScript, but I also know quite a bit more about it than many who would consider themselves fluent.
