• Worked in IDE Eclipse development environment using Clearcase, Enterprise Architect UML, ClearQuest, and C++ running on VxWorks OS. Developed multiple C++ embedded functions for the Pulse Analyzer Unit to receive multicast tip signals from multiple radar sources. Added C++ embedded function in the Navy Communication Jammer USQ-113 to scan target frequencies and jam when the signals are found above set threshold. Implemented Protocol Stack Layer 2 where Service Data Units or SDU is either… Show more • Worked in IDE Eclipse development environment using Clearcase, Enterprise Architect UML, ClearQuest, and C++ running on VxWorks OS. Developed multiple C++ embedded functions for the Pulse Analyzer Unit to receive multicast tip signals from multiple radar sources. Added C++ embedded function in the Navy Communication Jammer USQ-113 to scan target frequencies and jam when the signals are found above set threshold. Implemented Protocol Stack Layer 2 where Service Data Units or SDU is either encapsulated for delivery as a Protocol Data Unit or PDU for the next lower layer, or the encapsulation is removed and the payload PDU is returned to the next higher layer. Also worked Layer 3 where PDU to be packaged as either TCP or UDP type• Led team to perform decomposition of system requirements resulting in the documenting of verification test plans and procedures for multiple Radio products. This included requirement gathering, test plan creation, test strategies, test cases development, test case review, test scripts development from Business Requirement Document and Design Documents• Performed Regression and Final Quality Test (FQT) for multiple Sensor and Jammer development teams to ensure software and hardware components and peripherals are comply with both Functional and User Interface (UI) requirements. Analyzed test results in reports, created correction action requests, and verified fixes all in the effort of ensuring that products were dependable and of high quality• Actively participated in technical interface meetings with customer (the Army) and program sub-contractors for the Joint Tactical Radio System (JTRS) and Join Precision Approach and Landing System (JPALS) programs.
