Responsible for building and maintaining SunPower's Fleet Energy Data system. This system processes telemetry data for millions of devices, and allows users to see both real-time and historical data. On this team, I led an initiative to reduce energy retrieval latency by 30-50% and have provided more complete data to tens of thousands of customers by dynamically synthesizing data from various sources.
Helped build SunPower's Virtual Power Plant (VPP) system. Focused primarily on the service for reporting battery telemetry data to utilities, and creating a REST API-based "Admin Portal" that allows the product teams to scale the system without engineering help.
• Lead engineer for a 10-person team that designs and builds the solar array on CalSol’s 10th generation solar-powered vehicle. • Created an electrical design that maximizes solar power generation under partially shaded and damaged conditions. • Used SolidWorks to design a mechanism that allows a large, heavy solar array to be tilted up to 90 degrees to charge the vehicle while the sun is low in the sky.
• Created a detailed design specification that improved and standardized the hardware configuration for control cabinets in Doosan Gridtech’s battery energy storage systems, streamlining the design process and reducing cost. Used AutoCAD for physical and electrical schematics of the cabinets. • Created training manuals for numerous energy storage projects, to familiarize field workers with every relevant component in the system, including its control and power system configurations, O&M requirements, safety restrictions, and more. • Researched and advised the company about the total system cost and risk differences of various battery chemistries, including thermal stability characteristics, energy/power characteristics, control system impacts, and more. • Helped to integrate SCADA signals into an energy storage system’s control network.
• Worked with a Solar and Energy Storage Systems Trainer to create an 18-hour training course on energy storage systems for students looking to get involved in the industry. • Covered the chemistries, production processes, market trends, and installation procedures for a wide variety of energy storage system options. • Analyzed the viability of emerging technologies such as supercapacitors, flywheels, flow batteries, gravity-based storage, and more.
