- Collaborated with agile development partner Lockheed Martin to provide sustainment releases for the TTSE application
- Wrote scripts in Perl, Python, and shell to assist in the automation of software sustainment tasks
- Completed investigation, code design, code implementation, and unit testing on bugs found turning testing
- Integrated software from real world satellites to simulate hardware and memory management so that TTSE can properly simulate real world orbit events
Computer Scientist
United States Air Force
10.2019 - 07.2022
- Provide sustainment release support as a Software Engineer for applications that fall under the CCS-C portfolio
- Sustain release cycles consist of both bug fixes as well as enhancements to existing software
- Duties include working on two software development teams which consist of both government employees as well as government contractors (Kratos)
- Participate in daily stand-up meetings with the two development teams to discuss daily status as well as any issue/blockers
- Participate in Monthly meetings with the end user (US Air Force) to discuss upcoming sustainment releases as well as reporting current status of current releases
- Resource Configuration Manager (RCM): RCM is a system that supports the scheduling and planning of resources for establishing a contact with a Satellite in orbit
- Enhancements performed to this system was to make all resources when marked offline show up on the scheduling Gantt chart as unavailable as well as not allowing other users to schedule that resource in real time
- Development work done to perform this conversion consisted of examining legacy RCM code to see how it works as well finding what code it any could be reused
- Performed debugging all thought the development cycle
- Created unit tests in order to make sure all resources were working as intended
- Research how to send/receive Window AFX messages
- Performed Unit Testing in the development environment
- After developing the code for all the resources updated the Software User Manual (SUM) to account for new functionality that was added
- The technologies used to perform this work included C++, Visual Studio, SQL Developer, and Windows programming
- Satellite Telemetry API Development: Satellite Telemetry API consists of a vast array of processes/algorithms that are performed in a well-timed manner to give the end user reliable data
- The legacy API had to be reworked in order to fix erroneous data that was being given to the operator
- Work on this project includes examining legacy code and converting it to the new API framework
- Generate Minor Frame reports using Perl scripts to examine how and when telemetry points are being processed
- Performing Desk Checks on other developers’ conversion code
- Generating test plans with all telemetry points in order to conduct unit testing
- Unit testing of API processes/algorithms in the development environment
- Troubleshooting issues that come back from the test team
- Technologies used during this development include C, Visual Studio, Guacamole, Perl, and Bugzilla, Jira
- Human Machine Interface Development (HMI): HMI’s are the Graphical User Interfaces where telemetry gets displayed to the end user
- Development for HMI’s include bug fixes on existing HMI pages as well as creating new HMI pages
- Bug fixes require the addition of new Telemetry Points, changing conversion types, re-formatting data cells, and creating flags for when data goes out of a given boundary
- Creating new HMI’s consists of making a new HMI page which involves all the processes stated in the bug fixes
- Performed unit testing for bug fixes and new HMI pages both in the Classified lab as well as on Guacamole development environment
- Task Automated Operation (TAO)
- TAO’s are written in a proprietary scripting language that automate the process of making a contact with a Satellite
- Development on TAO’s include making bug fixes we well as adding enhancements
- Bug fixes require reading new directives from the end user and implementing these changes to the TAO
- Development work on TAO’s is done via the TAO Builder
- A code editor as well as a debugging tool for TAO work
- Once development is done unit testing is performed in the development environment via Procedure Builder
