I create and refine software requirements for complex problems to provide clear direction for a software design. Using data structure fundamentals, I create comprehensive designs with no more complexity than is necessary. Teams under my direction are effective in developing distributed software architectures that result in highly maintainable software designs. Using focused interactions with team members, as well as direct customer interaction, I bring together cross-functional teams to align goals, drive implementation, and ultimately provide features to the customer on time.I connect system, software, and product teams to scope and deliver software features on time. I work best with energetic teams that can come together and collaborate on software designs, and relentlessly drive execution to meet milestones and solve interesting engineering problems.Create maintainable, high quality code | Develop robust software API'sInteract with cross functional teams | Track progress with scheduling/milestonesWork with customers to define use cases | Mentor others to develop good practicesManage software teams through full cycle | Work in energetic fast-paced environments- C, C++, Java, Python, Shell scripting, assembly, Labview- Linux kernel/user space, embedded systems, OOP, JTAG, cross compilation- Linux/Unix command line, Git, Clearcase, Perforce, PVCS, source control- GNU, make, scons, Visual Slick Edit, Excel, Powerpoint, Word, Project, Visio

Founder And Chief Executive OfficerAccess AnalogBoulder, Co, Us -
Sr. Staff Software Engineer/ManagerQualcomm Dec 2002 - PresentSan Diego, Ca, Us- Led team in requirement definition, design, scheduling, implementation, and direct customer support of RF coexistence and interference mitigation between LTE and WIFI spectrums. Developed detection algorithms and mitigation strategies that resulted in improved LTE and WIFI throughput performance. Developed interprocessor API with external companies to support the feature. Patents awarded and pending. Coexistence solutions additionally included antenna sharing between modem and WIFI to reduce mobile phone cost and size.- Led power team in design, implementation, and debugging of power management subsystem across entire mobile device. Created algorithms to optimize idle processor state, active processor frequency and voltage scaling. Interfaced with Linux and Windows kernel to provide power management drivers used in millions of mobile devices.- Developed subsystems to provide resource management for modems used in the majority of the world’s mobile phones. Resources included timing correction, frequency drift, clocks, and antenna management. Complex algorithms were improved over time to improve accuracy.- Implemented and tested software to dynamically and intelligently control forward/reverse gain for a mobile network repeater which expanded coverage while minimizing the impact on the network.- Career management for 5 employees, wrote reviews, conducted interviews, remote office meetings -
Staff Software EngineerQualcomm/Ericsson Jan 1998 - Dec 2002Kista, Stockholm, Se- CDMA base station - supported field software upgrade, remote ftp/tcp/ip interfaces, hot plug- Software design and implementation of 3rd generation base station with new platform- Call processing software - implemented on PPC750, utilized to increase base station capacity, vxWorks BSP and driver development ethernet, serial, proprietary FPGA, PCI Bus.- Subsystem testing for voice/data traffic processing hardware acquisition, software debug. voice/data processing, base station interface and call flow design -
Sr. Software EngineerValleylab Apr 1997 - Jan 1998Us- Developed and maintained embedded software for a combination electrosurgical generator and endometrial ablation controller. Used two 80C51 microprocessors and 68HC11- Implemented closed loop voltage and current control to regulate power output to patient -
Software Engineer/Optical EngineerTexas Instruments, Defense Systems & Electronics Jun 1992 - Apr 1997Dallas, Tx, Us- Missile seeker project development of overall system control, gimbal line of sight control, hardware interfaces and drivers, tracker aimpoint prediction using a predictive filter. Used multiple DSPs and proprietary OS and image bus. Secret clearance.- Implemented real time servo loop to control/point a 600lb gimbal. Developed com port and DMA drivers, hardware interrupts. Created communication interface for MIL 1553 standard on embedded system and host PC. Also developed stress test and software reloading algorithms. - Developed and maintained a monte carlo optical tolerancing program (UNIX application) to predict actual performance of an optical/IR lens system after tolerances using a monte carlo tolerancing technique. Upgraded to include mechanical housing tolerances. Also predicted boresight aiming error due to vibration and shock events. - Optical test program - obtained the actual performance of a lens system. Automated both control and data acquisition. Also integrated into night vision systems to measure on target performance. - Campus interviewer for the Georgia Tech campus. Campus interviews, society functions, information sessions, presentations, and career fairs. -
Graduate Research AssistantGeorgia Tech Research Institute Jun 1991 - Jun 1992Atlanta, Georgia, Us- Researched, designed, and built off-axis elliptical fresnel zone plate antenna, published research- Real time servo loop, COM port and DMA drivers, optical lens tolerance modeling, interviewing
