Objective

I apply my knowledge of software engineering and computer architecture to the development of high performance, high quality software.

Skills

• Seven years of experience developing distributed, parallel, and fault-tolerant enterprise applications.
• Software- and system-level performance analysis, modeling, and optimization.
• Development experience in C and C++ using gcc/gdb, cvs, Microsoft Developer Studio, Intel VTune, valgrind, and Apple Xcode/Shark.

Employment

Senior systems analyst, 7/2001 - present, Lockheed Martin Management Systems Designers, Inc. / National Center for Biotechnology Information, Bethesda, MD

• Ongoing optimization, refactoring, and maintenance of BLAST code. Improved software engineering, testing, and release engineering practices.
• Contributed to the design and implementation of a highly available, database-backed load balancing system to parallelize Basic Local Alignment Search Tool (BLAST) search requests.
• Modeled software performance and applied knowledge of hardware trends in order to guide future software development and hardware purchases.
• Developed a BLAST benchmark suite to evaluate software and hardware performance improvements.
• Developed graphical systems to monitor the health of computational resources.

Systems programmer, 8/1998-5/2001, Cornell Theory Center, Ithaca, NY

• Contributed to the design and implementation of Cluster CoNTroller, a parallel batch job scheduler for Windows NT.
• Contributed to Microsoft's Computational Clustering Technical Preview Toolkit by porting PLAPACK to Windows 2000.
• Tuned, ported, and optimized scientific applications and libraries to a Windows-based cluster environment.
