United States

Message

At Hebbia, I developed and deployed AI-powered embedded systems, connecting firmware, sensor data processing, and on-device machine learning.

I also built LLM applications with retrieval-augmented generation and document retrieval pipelines, grounding responses in enterprise data.

At UKG, I developed and deployed custom LLMs for internal business applications. I also used A/B testing and statistical modeling to inform customer engagement, retention, and pricing strategies.

Earlier at UKG, I wrote C and C++ firmware for STM32 and ESP32 microcontrollers and built sensor drivers. At Jabil, I wrote and tested software in C, C++, and Python as a Software Engineer Intern.
