A majority of my work was on the Reno factory supply chain and model Y line, integrating part pick, drop and status features. This improved and maintained a manufactuing line uptime of >98% which accounts for 80% of company revenue.
I also created external APIs for third party suppliers to automate part shipments and internal APIs for centralizing the inventory system across all global service centers.

Low cost BLE enabled Insulin Pen - My first project, where I wrote custom FW timers, RNG, client-side encryption to reduce power usage by 30%. I also configured hardware end to end tests, maintaining >90% feature coverage that was required for FDA verification and validation. Along those lines I also user experience feedback from clinical trials with >1000 patients
Study watch - My next project was a low cost biosensing device, working specifically on the ECG monitor. I helped prototype initial internal BLE 5.0 framework for nrf52 series microcontrollers, brought over from the first project.
High frequency range hearing aid - I built the iOS component of a novel sync protocol with an iteration of an existing hearing aid to increase the granularity of higher frequencies.

My first role out of college, I worked on the Archemedes System, a Virtual Bronchoscopic Navigation System that uses fused fluoroscopy and CT scans to generate a three-dimensional model for real-time Guided Transbronchial Needle Aspiration. I worked on the testing framework for FDA validation and gathered data from small batch clinical trials.

As a part of the China Energy Group, I developed spatial analysis workflows using ArcGIS for tracking energy flow through city networks, producing interactive maps for geospatial visualizations. This work ultimately indentified the potential for 15-25% energy infrastucture reduction in Beijing

TubeMogul - Now aquired by Adobe, TubeMogul was an adtech company specializing in cross-platform video analytics. I worked on infrastructure automation project on the Maven system with Spring boot configurations, creating a monitoring dashboard for the servers across global regions and to load balance within regions.
BioRad - I worked on an internal tool to provide dynamic analysis on Digital Droplet PCR information. I created a Django application to injest large amounts of ddPCR data and sorted then displayed the information for scientists. The largest challenge here was optimizing the algorithms run on the data, which at first took 5+ min, but was reduced down to <1 min at the end of the summer.
ICHA - Remade the ICHA website, to incorporate bootstrap and PHPMailer.
