I'm an software engineer as well. I work for one of the top 3 waste management companies. I've worked on both consumer side web/mobile apps as well as operations side projects, both in hauling and MRF operations.
Oh interesting, we generally don't go to WasteCon due to how focused it is on public sector since we have a better product fit with independent haulers (we do have several municipalities using our software though). Maybe we should be going though - always good to expand our horizons. Feel free to shoot me an email at: my first name at edisoncode.com
