Callahan & Associates, Inc.

Jeremy Callahan, a.k.a. the App Man, specializes in developing software solutions for iPhone, Android, and Web Apps.

As both a web and App developer, I always conduct a thorough analysis of each project - every success and every failure - looking for ways to improve the process.

What I have learned in my career as a developer is that there are certain processes and principles that apply to every App development and launch, no matter the business or project. I am an expert at determining what it takes to get from idea to production-ready App. By now, I’ve seen it all. I can tell you exactly what bottlenecks will arise and how to work through them so they don’t derail your success. Every business or project is unique and different, but applying these core principles and processes will almost universally guarantee the project’s success.
