This is a scam. They are building an email list for their outsourcing service.

Hello, Guys! this is Arpan. I have created AppFixers to provide various application related fixes to App owners.

The idea of AppFixers is to track all the SDKs, 3rd Party libraries, integrations, Apple Documentations, App Store change etc.

32-bit to 64-bit conversion is just a beginning
