> The company I work for is in the middle of "modernizing" our backend tech stack. As part of this, a few years ago I was assigned a task that could not be completed with anything we had or could find in the marketplace. I designed and implemented a tool that allowed us to move forward (I'm intentionally not describing it); it has now been part of our production process for 6+ months;
The company had a problem (which was probably some idiosyncratic self-inflicted thing), and they hired you to solve it for them. They could have hired any one of thousands of other people to solve it, but it happened to be you. You solved it, and now it's done, which is great (mainly for them).
> Somewhere between $15-20 million ARR depends on it and yes, it has been rock solid and dependable.
Does any of that ARR in any way depend on other things too? Like a brand, marketing, sales people, some product, etc?
Not trying to be too snarky, and you don't provide too many details, but generally there isn't actually much value in tooling/optimizing backend or operational things. These things are only valuable in the context of the rest of the company, which they own, not you, so they can just keep on doing what they're doing and hire people to solve the rest for them when they need to.
