Implemented a WebSocket based telematics streaming and geofencing feature in the company's telematics applications. Supported live ingestion of location and other sensor data which was evaluated against user defined geofencing rules to generate alerts. Used successfully during the 2019 HackOHI/O hackathon for the Honda & Mobikit sponsored challenge.

• Amazon Web Services
• Python

Implemented an AWS appliance for the company's telematics application used for internal deployment in isolated AWS accounts. Critical to securing a large customer which required the ability to run the entire stack in their own AWS account. Implemented appliance operator controlled application updates through AWS Lambda based interface.

• Django
• Python

Implemented a prototype for deploying Django-based web applications to AWS CloudFormation managed infrastructure which supported automated zero-downtime rolling deployments. Presented internally to demonstrate the possibility of fully managed, fast, and robust deployments compared to existing blue/green deployment strategy in use. Packaged Python applications using PEX to bundle application requirements and assets into a single file. Rolling deployments implemented with AWS SSM and Lambda services to enable auditing and access control. Successfully adopted.

Worked with an intern to design and supervised the implementation of a tool to track AWS resource usage across all company AWS accounts. Implemented as Lambda functions, with an RDS managed PostgreSQL instance for state, and deployed through CloudFormation. Used to identify and deprovision expensive AWS resources that were no longer in use or created against current policy.

Migrated VoIP phone system from Asterisk to 3CX. Worked with the customer support team to design and implement automated call flows and related features.

Implemented an internal helpdesk using osTicket to prioritize internal devops support requests.

• Swift

Implemented a native iOS application for tracking medical symptoms, supplements, and medications for people with chronic illness. Migrated from Swift 1 though Swift 3. Implemented offline mode with on-demand two-way synchronization support using Realm DB.

Implemented a Windows desktop application to manage accounts for Physics department staff, faculty, and students.

Managing accounts involved coordinated changes to multiple systems synchronized through Active Directory. The application automated provisioning, archival, and password changes for accounts through a desktop user interface. Reduced the time required over the previously manual method by an order of magnitude and eliminated operator errors.

Designed and lead a team to implement a distributed soft-real time control system for Linux-based hosts. Reverse engineered serial, USB, and network protocols in order to write control system plugins for various industrial and diagnostic equipment. Worked closely with equipment vendors to diagnose and fix firmware bugs. Reviewed and approved the design of all applications built on top of the control system.

A mix of static equipment (i.e. vacuum pumps, valves, door locks, etc) and floating equipment (i.e. oscilloscopes, laser energy meters, cameras, motor controllers, etc) were used in concert to operate the facility's systems and conduct experiments. The control system provided an abstract interface for end users to inspect or manipulate all connected equipment via a web-based interface and client libraries (i.e. MATLAB, LabVIEW, Python, Lua). Small Mini-ATX x86 computers were available for staff to set up on demand in the facility which network booted a Scientific Linux 6 distribution that included the control system software. The control system supported hot-pluging and dynamic detection of all equipment connected to the local host which enabled end users to set up and tear down experiments quickly on their own. A lua-based scripting environment was available through the web interface for end users to quickly automate experiment setup and data collection.

Implemented an access control and safety interlock system for individual rooms in the facility.

Each door was equipped with an RFID reader on both sides and a magnetic lock which were connected to the facility's Opto22 programmable automation controllers. Staff was issued RFID cards which had associated access control rules. This system tracked who was in which room based on the last RFID access. It was used to ensure staff could only access rooms after receiving the appropriate safety training and that no one was present inside the target room while the laser was operating. It supported synchronising registered users and access control rules over a custom TCP protocol.

Implemented a system to automate operating the vacuum system used as part of the laser chain.

Vacuum pumps, valves, and sensors were connected to the facility's Opto22 programmable automation controllers. This system monitored the state of connected devices to determine the current operational state, provided an automated way to transition to a requested state, and provided an emergency stop feature that could safely bring the connected chambers and lines up to atmosphere without intervention.

• VBScript

Wrote an HTML Application that could be run from USB thumbdrives to automate collecting inventory information from Windows and MacOS computers. Reduced the time required over the previously manual method by an order of magnitude and eliminated data entry errors.
