Lead Architect/Developer

Responsibilities:

• Implemented a reusable and pluggable C++ framework for parsing XML files and returning an object graph representing the fields of interest with each filed as an object with type, offset in telemetry and size information.
• Implemented a pluggable framework in C++ that allowed each instrument specific telemetry parsing component to parse the telemetry and return each component as a stream that than gets used by the generic component to create the image in VICAR format.
