I worked at Sprint for fourteen and half years. I grew a lot from seeing Sprint working with landlines to the maturity of cell phones. The merger of Nextel, Boost, etc. Many changes and features that make telecommunication what it is today.
I was involved with many successful projects, web services, billing, going from 2G to 3G, 4G, and LTE. Working on tablets, cell phones, and even testing the ATMs.
The people were great at Sprint.
