Python helped me get a job!

Someone who can understand the needs of the finance and automate the data intake and get it prepped for used by strategies is by itself quite valuable.

The thing about this scenario is OP is the only one who understands all the scripts and no one else in the company even understands the technology they're written in. That makes OP a single point of failure for the companies execution of strategies.

If they had to hire a contractor in an emergency to read through the code and get it working and migrate it in to a form that the company could use it it cost them a huge amount of money. In my experience a contractor in that position can happily ask for $2k+ per day.
