Steven El Bitar
Ulm
Summary
Multitalented engineer with a solid foundation in computer science and communications engineering. Started academic career in computer science, gaining proficiency in multiple programming languages before transitioning to computer and communication engineering. Completed a bachelor's thesis on developing an MDIO protocol on FPGA. Earned a Master's degree in Communications Technology in Germany, combining advanced studies with practical experience through multiple student jobs. These included FPGA design, RF and microwave material characterization at high frequencies in collaboration with MBDA Deutschland, and optoelectronic projects with TRUMPF, Ulm where I developed Delphi code for mode tracking and thermal resistance measurement. Pursued a Ph.D. specializing in Monolithic Microwave IC (MMIC) design, having successfully designed, laid out, and submitted PLL system for fabrication used in clock synchronization and distribution in a planar phased array antennas, followed by performing measurements and validating results against simulations. Demonstrates a proven ability to integrate theoretical knowledge with hands-on design and development across diverse high-tech fields.
