Nathan Quinones

Nathan Quinones, President

While still in high school, Nathan Quinones began his career in IT as a computer operator, working backups and end of day jobs at night. He joined Custom Systems right out of college, as a programmer, learning on the job.  Nathan quickly learned programming on the AS400 and became a Senior Systems Analyst.  He also learned MAPICS XA and added Implementation Consultant to his skills.  He also worked as one of the primary developers with, now Vice President AX Consulting Michael Franchino, writing the Electronic Commerce module of MAPICS XA that Custom Systems developed and still supports today.

Beginning in 2000, Nathan started doing web development on the AS400, developing the EAX web portal. This gave Custom Systems the ability to create MAPICS XA related web applications as well as custom web applications for EAX clients.

Today, Nathan works hands on in many Custom Systems solutions such as Future Cast, COS, EAX, EC and Release Management.
