While working here, I developed in C code for Telxons to assist associates with performing their inventory counts. We were able to reduce the time it took to perform a full count of a single item by more than half. This exposed me to beginnings of corporate coding at a the largest employer and largest retailer, as well as gave me an idea of how a large corporation manages a wide variety of code bases and possible points of failure.
