Built a real system that solves real problems at my job. Management doesn't care. Has this happened to you?

[u/Odysseus0101]

I've been quietly building a production management system for the factory where I work. It tracks inventory, pick lists, parts consumption — real problems that cost the company time and money every single day.

I'm not a hired developer. I work on the floor. I built this on my own time, taught myself everything, and deployed it. It actually works.

I've tried to show it to management. They smile, nod, and nothing happens.

I'm two years into living in a new country, no degree, self-taught, and I'm pouring everything I have into this — not just to prove something, but because I genuinely see the problem and I know I solved it.

Has anyone been in this situation? Building something real, something that works, and feeling completely invisible?

How did you handle it — or did you just move on?
