SW / HW Co-Design

GEMM Weightlifter

• Assemble and test highly sensitive water sensor used to ensure cargo ships meets emission standards.

• Identify flaws and oversights in the circuit board testing process. Work together with the Production and Test Engineer to rectify and optimize.

Responsible for hardware and embedded system design for air quality monitoring IoT project. Broad responsibilities including, but not limited to, market research, components research, options for manufacturing and deployment, firmware engineering, hardware engineering and assembly, PCB design, debugging and testing.

• Continue development on the Air Quality Sensor from Fall of 2019 Internship

• Develop firmware further, implementing WebServer functionality, WiFi manager functionality, and Over-The-Air update features.

• Prototype 3D casing for the sensor, with plug-and-play capability in mind.

• Designed for manufacture a development board containing ESP32-WROOM, RTC, SD Card, and LoRA module using KiCAD, specifically for company use.

• Managed space, supported members, and built community for startups and Techstar Seattle programs.

• Maintaining inventory, and space facilities, ensuring resources for startups and members of the community are always available

• Re-organized and re-wrote outdated documents, including administrative documents and guides to use available resources

• Rapidly prototype a check-in system using Google Forms, Sheets, and Google App Scripts with JavaScript

• Develop an Indoor Air Quality Sensor using the Wemos ESP32, Shinyei PPD42NS dust sensor, and DHT11 sensor to provide data on temperature, and humidity

• Firmware developed on the Arduino IDE, using open-source libraries for the corresponding sensors

• Utilized MQTT protocol to transmit data packets, stored into InfluxDB hosted on a Raspberry Pi for data analysis

• Design PCBs to assemble and deploy system in a compact package
