INTRODUCTION 
Demonstrated expertise in designing and implementing robust, high-performance software and firmware for embedded, device driver and
real-time applications, including robots, N/C controls, scientific instruments and avionics. Experience encompasses interfacing robots
and scientific instruments with enterprise-class database systems and designing and developing data validation and analysis
applications. Extensive experience taking projects from concept to completion in several industries. A bachelor's degree in Applied 
Mathematics from California Institute of Technology provides a firm foundation for expert implementation of mathematical algorithms, as
well as providing a background helpful in communicating with scientists and engineers in other disciplines.

* Collaborated with project manager/DBA in designing a Laboratory Information Management (LIM) database schema in Oracle.
* Designed and implemented software in C# to acquire data from a plate reader, do a quick analysis for QC and allow the user to select
readings for upload to an Oracle database.
* Designed and implemented a C#-callable multi-threaded ATL/COM module in C++ to provide file IO and serial communication
functionality for the C# application.

Vertex Pharmaceuticals Inc, San Diego, CA, Software Architect & Consultant, 2001 - 2004
* Software architect and lead designer/programmer for 3rd generation early-phase drug discovery screening system.

consumer templates to access Oracle or SQL Server database instances using OLEDB.
* Analyzed system at an early stage for performance bottlenecks and modified the design of the database and the middleware
component to provide 200 times the performance of the legacy compound management system for the critical function of finding the
physical location of a set of compounds to be used for a screen.
