Client had a mobile testing application that was experiencing performance issues and customer support issues at scale. Technology used to create the ap was a NoSQL (MongoDB 3.0), python, JavaScript application. Investigation identified numerous issues including latency in returned data from MongoDB caused by non-sequential needs for data, security issues, and latency in implementation needing to deploy entire dataset to mobile device. Hired and led team to re-work mobile ap as a web-based implementation which only required a small subset of the data to be transferred to the mobile device.

Client had an emergency situation regarding a custom Windows .NET application that was an online store, a CRM system, an enterprise shipping/printing management system, and an employee management system.
