I work with a different kind of legacy system. It was retrofitted to work with SOAP, OOP, and some other modern stuff, but none of the old farts bothered to learn it. When I inherited a SOAP service that system used, I had to learn a lot about it to get what I needed.

And honestly? It's been a lot of fun. It's a unique kind of challenge, I've practically gained celebrity status at work, and even if it's nothing I'll be doing long-term it shows how I can pick up weird systems and work with others to make some miracles happen.
