Our technologically savvy team all began with two UNH Computer Science roommates – Ryan Zarick and Caleb Banister. At the University of New Hampshire they decided early on it was their dream to go into business together with complimenting talents, and a desire to work work on mobile applications and websites. Jumping in early on they began their careers working on side projects while in college, and began a self-funded start-up company that has worked with some of the coolest technologies out there! As the company grew the guys decided to bring on an another fellow graduate who they had worked with all throughout college at the UNH-IOL Cassie Zarick, knowing her talents would compliment the team with her business background and passion for technology and working with people!


Coder Den has since evolved into a well-established boutique style development firm, and continues to impress customers by keeping the flame of passion lit always providing the highest quality applications/websites and experiences to our customers.
