• Axsun Technologies designs and manufactures products employing Optical Coherence Tomography (OCT) techniques. They serve the Telecom and Medical markets. The medical products, which are the ones that I worked on, are.
• Designed a Handpiece PCB based on the ADI Blackfin Microprocessor for a Fiber optic Cardiac Catheter System. The Handpiece is used to spin and pull back the Catheter within the patient while collecting arterial image.

• Seahorse BioScience designs and manufactures extra cellular flux analyzers used for in-vitro assays. Using LEDs, fiber-optics and fluorescent probes, oxygen consumption rates and acidification rates are measured in.
• Implemented processes to improve PCB yields from 50% to 95+%. PCBs represent approximately 30% of the product material cost.
• Designed fixtures, wrote software, and wrote procedures to automate PCB testing. Reduced test time from several hours to approximately 20 minutes.
• Redesigned a transimpedance amplifier with a gain of 10 billion to improve reliability.
• Designed PIC based temperature controller PCB to control temperatures in the instrument within 0.1°C.
• Acted as liaison between consultants and manufacturing for the introduction of a fluidics system. Duties included.o Documenting the instrument.o Procuring the parts for and supervising technicians on the beta build.o.

Aushon BioSystems is a biotech startup, which designs and manufactures a protein deposition robot used to create biological assays. The system contains a large XYZ stage, which uses servo driven lead screws with linear encoder feedback to transfer samples from microtiter plates to substrates. The system has a positional resolution of ½ micron. Developed.
