Instrumental in Finesse's growth from a small startup to a mature organization with 200+ employees and established product lines. Played a pivotal role in designing and developing all company products, encompassing hardware and firmware components. Expanded expertise as an individual contributor in hardware, firmware, and overall systems design throughout this process. Assumed full ownership of the entire system, demonstrating leadership and technical proficiency.

• Oversaw the fourth generation of Bioreactor controller design and devlopment.• Distributed, multi-board, multi-processor system with local control.• Highly responsive and configurable. Distributed architecture adaptable to many different use cases.• Hardware and firmware design was reused across many systems.• Able to control many different vendor’s bio-processing vessels with this system.

Hardware / software and firmware architect, Yocto BSP port and bring up, C++ application designer and developer.• Used Yocto to build the OS distribution for the embedded Linux main controller• Based on the CM3 from Raspberry PI to save cost and leverage the open source community• Designed, coded & debugged (GDB, GDB Server, Lint, etc.) both the Yocto build system and the multi-threaded C++ application• Brought up the initial hardware and subsequent PCB iterations• a multi-threaded C++ application, run time configurable, real time data gathering and translation server ◦ reduced 3rd party licensing by 50%, and increased communication efficiency by 2X at the same time.• Git version control and bug/requirement tracking using internal gitlab server• Integrated with the continuous integration and release build system

Hardware / software and firmware architect & developer:• Controlled 3rd party mass flow controllers and a matrix of 18 solenoids with custom hit and hold firmware resulting in an 60% reduction in power usage.• PIC32 micro-controller with Ethernet and rs485 communication, PLC to route the hit and hold circuit.• Designed the code and programmed it in C. Power on Self Test code to verify the HW• Used Oscilloscope and protocol analyzers to uncover bugs.

• Optimized the FETs for power savings eliminating the heat sink and improving efficiency• Corrected the commutation to prevent shoot through using a scope to visualize the drive signals• Reworked the ISR to move most of the code to the foreground to fix jitter issues• Adapted the design to work to control four different vendor’s bioreactor product lines, enabling Finesse to be our customer’s go to solution for controllers for any system.• Worked with biologists to qualify and optimize the design

• HW & FW designed and coded Ethernet / RS485 Modbus gateway• Expanded functionality for pinch valves with Jr. Engineer under my direction• Saved licensing costs by implementing a paging system for serial numbers, etc.

• HW & FW designed and coded• High performance wheat-stone bridge (24bit ADC) driver code• Reduced the competent count to optimize for cost, manufacturability and test, resulting in cost savings of 50%

• Run time configurable analog 4-20ma/0-10v interface board• Designed SPI bus based isolated interfaces• Low level hardware abstraction layer & drivers for the SPI bus and its chip selects plus the DAC/ADCs

• Isolated the circuity to prevent galvanic loops• High impedance pH (>1Gohm) and nanoamp DO electrochemical probe designs• Used inexpensive components and compensated with calibration routines in the firmware• Translated requirements from the scientists into HW/FW & Labview & calibration test station

• Premier product line of Finnese: Optical dissolved oxygen and pH sensors• Linux based embedded firmware, in C++. Based on build-root & built from scratch, then Yocto• Remote GDB debugging, debugged Linux serial driver for RS485 1⁄2 duplex communication• Ported the design to Atmel's AT91 processor• Managed the hardware consultants• Extended interface into a virtual transmitter that emulated the LCD and keypad over the wire

Designed and developed many products from concept to deployment. Specializing in the application of firmware to the product solution. Was responsible for developing and maintaining the firmware on the entire fiber optic product line.I utilized processors form the 8051 to the PPC403. From no OS to PSOS. Helped design and debug a VHDL IIC hardware solution for a multi-master solution.HOADesgined the embedded code to control 5 lasers.TranspondersDesigned the code to remotely monitor an node.Nodes:Designed the firmware to control and monitor fiber optic receivers and transmitters. I managed consultants and 3 other embedded engineers plus a hardware engineer. Developed on Altera's nios processor.Pizza Box unitsUsing VXworks I developed an snmp based controller for fiber optic transmitters and receivers. I was responsible for coding the main algorithms and integrating the SNMP engineer's design.

Senior Firmware EngineerLow Cost DFB:I took legacy code and debugged it. Using just a logic analyzer was able to find where the watch dog was timing out. Using this information I was able to prove where the issue was. This product was responsible for greatly increasing the revenue stream and making it possible to win big new contracts with the likes of AT&T.
