The good news for me is I got hired again, almost instantly. The bad news for this project is... it is a side project again.
I still love to tweak performance for websites and web apps. Squeezing every single millisecond from a database transaction is just addictive. But I'm not doing it on a daily basis anymore.
However, I'm sure the idea is good and there is a market out there, waiting for this product to see the light.
