Wrote micro-services platform used to build the Electrfied Miata (see bbitnerblogs.com/e-miata). Using Raspberry Pi 4 for soft real time tasks (down to a few milliseconds) and Pico micro controllers and micropython for hard real time tasks, like monitoring vehicle speeds. Designed and implemented soft real time, multi-process, multi-machine framework on Raspberry Pi 4including publish/subscribe features using TCP sockets, to create cohesive solutions.Designed Rev Matching system using Embedded Pico with micropython and PIO assembly to allow adirect drive coupling but still shift properly with the original manual transmission.Wrote system playback tools to simulate running the car on a laptop.Coded SPI communication with A/D chip for throttle, designed custom throttle response curves usingnumpy’s polynomial curve solvers with better than a 20 ms response time. Wrote calibration tool forthrottle. Integrated speed sensor with sampling speed of 100Khz using Pico microcontroller and micropython.

Software Architect, Machine Learning, Data AnalysisDesigned and developed systems with Pandas to identify key metrics, find correlation, verify andcorrect market data.Designed and implemented scikit-learn gradient boost risk and reward estimators.Wrote automated data processing programs to normalize options data.Automation of Tick Data for import, update and computing statistics.Trained ‘You Only Look Once’ (YOLO) AI to identify market trends in real time.Created trade simulation tools using PyQt technology.Wrote interface to ThinkOrSwim to monitor active positions and locate new opportunities.Validation of correlation to new data when using gradient boost estimators.Wrote many root cause analysis tools to isolate market movement events.

Created diagnostic and commissioning tool for ERX class 8 truck. Tool capable of real time display ofmultiple components on 3 CAN busses, with ability to display both component specific faults andsoftware version. Tool also able to run specific tests and report results to Hyliion Cloud. Automated 8hours of work into 15 minutes per truck. Awarded the Gigawatt (highest company award).Designed and developed correlation tool for use between system insulation and 50 other factors.Designed, implement and deployed IOT diagnostics, data transfer and digital twin update on greaterthan 60 EX trucks using Linux, C and Python. This involved upgrading Python to a newer version to becompatible with Hyliion’s Azure IOT cloud. Designed packaging so standard apt-get commands wereused to upgrade/install IOT packages.Designed and implemented remote update for the embedded Linux platform on the EX truck.Administrator for Security access (SSH keys) and Debian repository for EX truck fleet.Debugged multiple issues with Kontron Linux embedded platform include cellular, GPS and software onEX truck.Produced real time multi-bus CAN monitor to automate commissioning tasks.

Introduced VAS to open source which included Linux, Python, MySQL and apache web-services. Implemented major portions of MandateIP framework and tool kit (~50K lines of Python). Continue to implement new projects and expand MandateIP capabilities, including PyQt based graphical hardware emulators.Converted company QNX infrastructure to open source which included Linux (Suse, RedhatEnterprise), Python, C, MySQL and ApacheImplemented major portions of MandateIP (a distrubuted processing framework) and tool kit (~50Klines of Python)Built custom Linux kernels for consistent soft real time performancePorted Python to ARM2 (Sharp Zaurus) to allow MandateIP to run on mobile warehouse devicesMandateIP runs 24 x 7 x 365 at major Distribution Centers for HEB, American Eagle Outfitters, LLBean and many othersDesigned and implemented positioning control code for the Radar array at National Radar and TestFacility (Holloman AFB) using C and QNXDesigned and implement numerous custom interfaces to electro-mechanical systems like tilt traysorters, Allen Bradley PLC’s, laser range finders using both C and Python

Designed a build system for complex build situations, including generated code(IDL) and multiple platforms (Unix variants, NT, OS2, and OS390) (~7,500 lines Python) see "http://www.xiexie.org/forge/overview.html"Analyzed problems with current build system, researched and designed alternative solutions, developed prototypes (15,000 lines, OO-Perl), lead implementation.Gave presentations for management and users. Also wrote programs to automate the conversion between build systems.

Computer Integrated Manufacturing (CIM) Manager 1997 "Managed 11 employees, 24x365 support for factory production systemsimplemented maintenance procedures for upgrades and version control.Proposed the necessary procedures for SEI and ISO 9000.Designed a migration path from custom configuration to standard systemsSenior Development Engineer 1996 "Modified/enhanced the Statistical Process Control programs andsubscriber/notification mechanism on QNX based systemwith 200 nodes. Wrote programs to manage archival and sizereduction of Equipment Management System/SPC database's.Upgraded build system.
