• Software Architect

  • Apr 1999 - Present

  As software architect I develop frameworks and best practices for rendering, persistence and analysis of our enterprise and public web applications, and our back-office services. Researching, testing and integrating new software tools and techniques is another responsibility that enables me to improve XFI's products and processes. By providing technical assistance, guidance and coaching to other software engineers I improve the reliability and maintainability of our code.

• Electronic Engineering Design Consultant

  • Aug 1995 - Mar 1997

  Brought on as a consultant to work on the development of a new generation of mid-infrared ambient air analyzer. I designed a DSP-based data acquisition, and motion control printed circuit board, and wrote the assembly code for the TI TMS320C14 processor to implement a PID servomotor controller for wavelength, a phase-locked-loop chopper motor drive, and synchronous data acquisition and analysis. The product exceeded goals for performance and cost-efficient manufacture and more than 20 years… Show more Brought on as a consultant to work on the development of a new generation of mid-infrared ambient air analyzer.

Igen International, Inc.

• United States
• Biotechnology Research

• Embedded System Software Engineer

  • May 1993 - May 1995

  Developed embedded C code for IGEN's Origen Analyzer, an instrument produced to test, demonstrate and develop IGEN's proprietary electro-chemiluminescence (ECL) detection technology for immunoassays and DNA probes. The code ran on the OS-9 real-time operating system on a Motorola 68332 microprocessor. I developed code for motion control, data acquisition, waveform generation/analysis.
