Excited to be working on the latest and greatest emerging SSD technologies.Firmware engineer working on Front End and Common Services firmware of consumer and enterprise class SSD devices.Performed development on Common Services and supported RDT efforts of a consumer level device that is qualified with multiple vendors and in mass production. This effort involved on-site support at multiple locations including international travel.

Software architect and lead developer for an entirely new system designed to address a long standing issue with storage devices in data centers. It involves the development of custom rack mounted hardware and server system software. This work involved Linux application and device driver development as well as embedded firmware. The work was performed in C/C++, Python, and Perl, and shell script

Responsible for new product development, sustaining programs, and solving issues that escalate to the highest levels.• Member of the Core Team (matrix program management team) on a Shingled Magnetic Recording (SMR) hard disk drive program. The project maintained and delivered despite an aggressive schedule. Personally responsible for Debug and Failure Analysis capabilities, but the nature of the Core Team demanded assistance with all aspects of the project management team.• Successfully identified system level issues affecting customer qualification. Instrumental in providing feedback and solutions to the customer to ensure their success and acceptance of the product. This work involved debugging Windows, Linux, and embedded Linux systems to determine root cause and then develop a fix or workaround for the issue. Most recent effort involved a cable TV set-top box (STB).• Successfully managed a software caching driver software project that was released to volume production by first tier customers. Held an active role in both development and debug of this Windows caching device driver which was written in C with some C++.• Member of Open Source Review Board. Member of the core team responsible for ensuring compliance with all licenses for Open Source Software in use by the company. Selected compliance and audit tools as well as monitored their use and results. Reviewed and approved Open Source efforts within the company and set policies and procedures for their release on the Internet.

ASIC verification manager in the hard disk controller group.• Managed the introduction and successfully completed first System Verilog testbench. Project involved obtaining management buy-in, training, and consultants (to assist team). Project completed on time with highest quality metrics achieved by the group in modular verification.• Managed verification teams responsible for all host interfaces for hard disk controllers developed by the ASIC group. Successfully taped out SAS, SATA, and USB interface solutions.• Managed verification of NAND subsystems that are currently shipping in volume production. The testbench used was the first System Verilog testbench and was “first time right”.• Integrated and verified hard disk read channels on several hard disk controller designs. This involved integrating the IP from the vendor and then modeling the interface and programming the hard disk firmware.

Verification and system integration engineer responsible for HBA ASICs.• Verified PCIe and Ethernet interface (sideband MB management) on the latest FCoE ASICs. This involved integrating the IP, firmware and drivers. Coding and debug efforts from firmware and device drivers was involved. One patent (sole inventor) is granted in this area. This work was performed in Verilog, C, custom RISC assembler, and shell scripting. It involved the use of bus and logic analyzers.• Successfully ported device to Cadence Palladium and verified all interfaces, firmware, and device drivers (Windows and Linux). OS certification scripts (WHCK) passed before taping out. This work was performed in Verilog, Custom RISC assembly language, and C.

• Managed a team of application engineers responsible for integrating WiFi devices into various appliances. The team successfully deployed Embedded Linux based systems to produce WiFi gateway products used by multiple tier one router companies. This was a hands on role where Embedded Linux driver and script development was performed. The work was performed in C and shell scripting.• Managed a team of application engineers responsible for maintaining the Embedded Linux Board Support Packages.• Worked with engineering team to identify volume manufacturing issues and then developed solutions to satisfy production requirements. Personally developed a utility in C to support Flash imaging on the production line to resolve a high DPPM issue.

Manager of a group that built and maintained tools for the HBA firmware team. • Led successful effort to port GCC and its complete tool chain to the QLogic internal RISC processor. This effort led to significant reduction of logic bugs as assembly based code was ported to C. Productivity was improved by use of debug tools like GDB instead of logic analyzer traces.• Managed the support of failure analysis tools and custom assemblers for custom RISC processors.
