Related Experience
- Qualcomm Senior Engineer - August 2012 to present
- Debug Linux kernel and application functionality and performance at all levels – from high-level software design to instruction traces and processor pipeline interactions
- Develop tools in Python, C, and Bash to drastically accelerate data-gathering and analysis for software and hardware optimization, including lightweight container format and infrastructure, allowing automated profiling across thousands of workloads – potentially saving thousands of hours of engineers’ time
- Pioneered basic block vector-based correctness validation for workloads run on software performance models, preventing undesired behavior and ensuring results can be trusted to make hardware design decisions
- Adapt open-source software (QEMU, CRIU) for internal needs and contribute changes upstream
- Supported mapping performance data from software processor models to benchmark source code symbols by adding semihosting support for perf events in the Linux kernel
- Influence next-generation processor design by creating/analyzing processor performance micro-benchmarks
- Optimize Android/Linux application and library performance for Qualcomm’s mobile and server processors
- Real-time Linux Systems Research at Virginia Tech - August 2010 to May 2012
- Formulated and empirically evaluated cache-aware real-time scheduling algorithms and partitioning schemes
- Researched and implemented techniques for quickly communicating kernel scheduling decisions to user space
- Qualcomm Software Development Engineer - Summer 2011
- Developed and supported snapshot/restore mechanism for next-generation mobile processor simulator
- Co-developed 'fast-forwarding' for the same processor performance model
- Virtual Environments Research in Computer Science - Spring 2010
- Conducted user studies testing the effects of interaction fidelity on procedure memorization
- Developed test environment using Blender, Python, and interfaced with VR hardware using C++
- IBM Emerging Technologies (jStart Team) - January 2009 to February 2010
- Architected, programmed, tested, and presented new distributed mashup technology utilizing XMPP, custom Java server, MySQL, HTML5, JavaScript, and CSS
