I. About Me

Data engineering, materials science, and business operations.

My background spans data engineering, battery manufacturing, and materials science. I currently support business operations and strategic initiatives at my family's agricultural enterprise.

My engineering experience centers on battery manufacturing telemetry, cell formation protocols, and computational materials research. At Tesla (May 2023 – December 2024), I worked as a Data Engineer (P2) and Senior Data Engineer (P3), where I built the FAST (Formation Analytics Screening Toolbox) library, maintained the real-time RAPID telemetry dashboard for the Berlin and Austin Gigafactories, streamed Milmont facility sensor data to AWS, and built API recipe synchronization workflows for 4680 battery cells.

Before joining Tesla full-time, I worked as a Data Science Intern at ATOM Science in San Francisco (September 2022 – May 2023) while completing my M.Eng. at UC Berkeley, applying transfer learning and active learning in Python to screen molecular databases for drug discovery. Earlier, as a Process Development Engineer in Formation at Rivian (September 2021 – September 2022), I developed six cell formation recipes for the R1S, R2, and R3 programs and wrote precharge Solid Electrolyte Interphase (SEI) anomaly detection protocols.

Today, I focus on business operations and strategy at my family's agricultural enterprise, helping manage day-to-day operations while exploring practical ways to apply data analysis, field trials, and clear stakeholder reporting to agricultural workflows.
