About

As a Senior Software Engineer at Fidelity Labs, I’ve been a core contributor and feature lead helping to build early-stage startups for Fidelity to enter new markets. Additionally, I've built agentic AI systems used by business and engineering teams across the portfolio of Fidelity Labs businesses.

I graduated with a Computer Science degree from Duke University in 2022. In Fall 2026, I’ll begin pursuing my MBA at Kellogg in the full-time MBAi program, a competitive cohort of 50 students that includes a joint degree in AI from Northwestern's McCormick School of Engineering.

After Kellogg, I intend to leverage my business acumen and technical background to help build transformative AI systems.
