Responsible also for several custom applications of the PMC 12G SAS expander and controller families.• Effected the transition of the Maxim FW engineers into PMC and set up the development infrastructure in the new PMC design center.• Project lead of FW development for the small port count, 6G SAS expander that was acquired from Maxim. Developed from rough prototype to full, hardened, production release (RTP), including fully productized supplemental customer tools - GUI (configuration/data eye mapping), SPIFlash programmer (JTAG), and complete documentation suite.• Led the project for the SATA drive slicing expander application for HP Moonshot program. Designed the configuration/management module and I2C communications protocol to the HP chassis manager module (iLO). Designed the chassis manager emulator (development and regression testing tool).• Project lead for the out-of-band (TCP/IP) configuration and management module application for the 12G SAS expander. Designed the TCP/IP command server daemon and dispatcher.• Developed SMP, STP virtual phy drivers and managed the IP verification effort for the 12G SAS expanders (Xenon, Cobalt) that were acquired from Maxim.
