  Part of a cross-functional agile team and involved in the complete life cycle (design, development, testing and maintenance) of FastDDS, eProsima's open source implementation of the OMG DDS specification. FastDDS allows for real-time distributed application communication, with a focus on maximizing throughput and minimizing latency. Therefore, special consideration is given to efficiency, thread blocking and inter-process synchronization mechanisms.
