• Some of the data was live satellite data feeds, several columns were derived data using the actual satellite data feeds. I was given 10-year-old documentation that was not always legible. (A copy of a copy of a copy). I created a spreadsheet using the documented formulas and discovered the legible calculated data was correct only 30% of the time. Satellites do not have negative velocities. I told my manager I can reverse engineer the report, but this is a 6-to-9-month effort, not six weeks.
• Implemented Micro Services based Architecture using Spring Boot and implementation of Business Services using Spring Boot.
• As the position was funded overhead, not Customer Deliverable (CDRL), Northrop Grumman opted not to fund the completion of the work. During my program debrief my manager shared with me, "That's what the last engineer we hired said", with respect to scope and level of effort.
