At the CreateX-backed startup overhauling feminine hygiene with the Internet of things, was responsible for defining and prototyping the solution architecture for the initial vending machine. Deployed a secure, bidirectional IoT network that translates customer payments into an automatic vending of items. Researched power supply architectures for a device with constricted space when power outlets are unavailable and self-recharging is insufficient. Tested peripherals and wrote firmware. Transitioned the original Squarespace site to Django to stabilize the connection between the site and the device.

Worked with the team that designs and deploys the equipment, standards, and procedures to diagnose and repair failed legacy and current products.Analyzed schematics and source code to determine and correct multiple failures across several hardware and software systems, including Roadster sheet testing station and an assembly line real-time result viewer. In troubleshooting a Media Control Unit (MCU) firmware flashing station upgrade, recognized for contribution to worldwide service and productivity goals by launching two new stations.Overhauled a webapp with Flask and jQuery to index and search over 20 million files. Expanded search parameters to include filename, author, revision date, and content type. Implemented regex and full-text search mediums to balance accuracy with speed.Used Python and JMP to parse hundreds of sheet test results and visualize the effect of cell location on the occurrence of false-negatives. Successfully identified several localized error regions.Authored documentation with extensive diagrams, instructions, and troubleshooting methods such as RCA maps to guarantee stability. Track progress in Jira sprints to provide visibility.As part of a 12-hour hackathon to cut cycle time at a critical bottleneck in a general assembly line, performed time studies and determined the most common failure modes over a large data set. Team reduced time by 50%.
