06/97–05/98 Xerox Corporation Software Developer
Key Skills: C/C++, GNU Toolset, MS Visual C, 8051 Assembler, MS SourceSafeDeveloped user-interface for consumer multifunction peripheral product.Developed assembler code for display module.Developed task to handle menu-navigation, key-presses and display.Code was developed to run on PC before hardware was ready.
04/95–09/96 Data General Corporation Software Developer
Key Skills: C/C++, GNU Toolset, CEXEC, SH7000 Assembler, Watcom C, MS Source IntegrityDeveloped kernel code for handheld computer product.Developed and coded a robust method for loading new kernel software over existing kernel in FLASH memory.Added daemon and driver, supporting barcode reader.Added keypad call-back facility to enable applications to reassign keys.Added facility for loading and registering fonts.Added Clock/Calendar conversion routines and insured Y2K compatibility.
10/93–09/94 American Surgical Technologies Corp. Eng. Project Mgr.
Key Skills: C/C++, MS Visual C, 8051 Assembler, 68HC05 AssemblerImplemented an ANSI-compatible driver for the new product's character-overlay feature.Simulated this new 8051-based product on a PC.Modified software to improve performance of the auto-iris feature of the system's built-in light source. Specified materials and wrote software for a cost-reduced version of the product.Developed artwork for CCD-based cameras used in 3-dimensional endoscope product.
04/90–10/93 Kontron Instruments Software Project Mgr.
Key Skills: C/C++, MS Visual C, 8051 Assembler, TI-340 Assembler
Worked on development of Intra-Aortic Balloon Pump product line:Replaced existing dual-68000 design, card cage, and 6 PC boards with a single-board computer containing all peripherals, a 68332 CPU, TI-340 video processor and 8051 microcontroller used for pump motor-control.Merged OS and application code running on each 68000, to run on a single 68332 CPU.Specified a new source of LCD displays. Modified the software using macros to adapt to this display.Designed hardware for a cost-reduced version of the pump using current technology.Merged code for entire product-line to a single code-base.Developed a PC-based application to control a machine to fabricate material used for vascular-grafting:This machine, similar to a lathe, consists of a stepper-motor-controlled spindle, a spray-nozzle whose position is controlled laterally with another stepper motor. By varying the rotational speed of the spindle and the lateral speed of the spray-nozzle, varying degrees of length, thickness and density of the material is achieved.The application also allows the user to edit and save multiple configurations for various material properties.
05/88–4/89 Abbott/Omni-Flow Software Engineer
Key Skills: 68HC05/68000 Assembler, CAdded new features to 4-line programmable infusion pump based on the Motorola 68HC05 processor to read bar-codes from labels attached to medication containers, indicating drug name, patient name, dose, and expiration date.Ported control board code to new 68000-based design.Developed a PC-based application to download a given hospital's drug formulary into the device; a list of drug names and their associated numeric ID's.Developed another PC-based application that allowed the pump to be controlled remotely by a PC via an RS-232 serial link.
Omni-Flow was acquired by Abbott Laboratories in February 1989.
