RF Systems Engineer @ R&D on RF and electrical systems for LEO satellites and ground applications. • Software Defined Radios: digital modulation / demodulation, carrier / clock recovery, data encoding / decoding performed on general purpose computers or custom hardware. Experience with ECSS / CCSDS standards implementation. • RF hardware design and test for satellite and ground-based transceivers with RF output power between 1 and 100 W. • C++ / Java / Python programming for data handling hardware control software. Implementation of a distributed ground station control and data distribution software capable of handling multiple missions and ground stations at the same time. • Development of a flexible and modular line of solar panels for satellites ranging from 1 to 50 kg: design for manufacturing re-using commercial technologies and processes. • Design of a modular power system for small satellites, harvesting energy from solar panels and storing it in rechargeable batteries. DC/DC power stages and maximum power point tracker design. • Practical experience in integration / on-ground testing and in-flight testing / debugging on several missions. From September 2010 to Present (5 years 2 months) Delft Area, NetherlandsResearch and Teaching Assistant @ • Performing lectures and lab sessions for Master students (10 - 100 per class). Courses were related to electronic systems design, communications and in particular software-defined radios, system engineering and architectural design. • Coordinate Master students during their thesis. • Research and development on MPPT and power conversion stages, distributed architectures for failure tolerance, radiation effects on semicondictor components (with practical experience performing radiation tests) and software defined radios. From January 2007 to August 2010 (3 years 8 months) Torino - ItalyRF Systems engineer Internship @ Software defined radio development for satellite communications. Digital data demodulation was performed on a general purpose computer: the main goal of the project was validating a low-cost architecture to be deployed in multiple remote locations with full automatic control. From July 2009 to December 2009 (6 months) Delft Area, NetherlandsConsultant @ C and C++ professional training courses teacher. From September 2004 to April 2006 (1 year 8 months) Turin Area, ItalyInternship @ Development of a functional test strategy for NAND FLASH devices. From April 2004 to July 2004 (4 months) Naples Area, ItalyNetwork Administrator @ Network administrator for the local Health agency. My main task was designing, deploying and maintaining small LAN networks in the different offices and managing users data (privacy, security). From January 2003 to February 2004 (1 year 2 months) Turin Area, Italy
