Career History:

Consultant – Sr. Software Engineer, Sr. DevSecOps Engineer (remote) client – Honeywell and Verizon 2/2021 - 1/2023

Most recently running a modification / enhancement software project to improve and modernizer virtual space awareness within the Aerospace industry. The project increases the accuracy of GPS measurements and resolution another 20 percent. Use of Visual Studio and VS Code. Also, working with Oracle DB, informix DB, SQL, I translated Informix DB to the map data into Oracle when company acquired a small company. I had driven security measures and testing in both Azure and AWS. Online security for any communications were a top priority and strictly enforced. I used Terraform and MicroServices to communicate certain functions dedicated to traffic and logic, and to create playbooks for infrastructure configuration for the entire project along with scripting in Linux, Python.

As Domain Consultant and DevOps lead and DevSecOps, I designed applications interfaces for Verizon service notifications, incidents, alarms, and service orders with total party alerts end to end company and customers. All the middleware in Java and Python used to connect API’s to SnapLogic. Using automated logic from ServiceNow and conditions via SnapLogic Integrate logic, we were able complete 100% messaging in just a few months, using C++, C#, dotNet, Java and Python plus scripting to interface in linux modules plus DevOpsSec functions and using tools as Cmake, Nmake and the like. Using GitLab and GitHub for both projects. We used COM and DCOM components along with ATL with connected environments to do testing of bank feeds to stress programs on either side of the communication link and allow troubleshooting from both sides of customer links to sort out problem areas. Terraform used to creat plans for the systems and environments for testing and QA. Another project for HP computers and Printers, I aided in consolidating the two huge databases into one for sales people to mix and match computer upgrades allowed and matched to the selected features on the base computer model. The complex logic for features that the logic checks and restricts certain non-configurable items was a huge success. Using C++, Python C#, dotNet and Java to complete logic for notification logic with DevSecOps role for added functions along with Java Server and Java Beans the company’s core applications. I run Kubernetes and Docker for some services for the last 5 years.
