Experience

Jun 2026 — present

Undergraduate Researcher · Georgia Tech CyFI Lab

Researches efficiency and adversarial robustness of NVIDIA's Nemotron-Elastic model family at the Cyber Forensics Innovation Lab: built and benchmarked 123 elastic subnetworks (4.84B–12.31B parameters) on an H100, identified 24 Pareto-optimal accuracy/latency points across the released 6B/9B/12B budgets, completed sandwich-sampled progressive shrinking over 3.28M tokens, and is currently investigating jailbreak transfer and upstream data-poisoning persistence across sibling subnetworks.

Summer 2026

Y Combinator Startup School

Founder participant who used customer discovery, startup credits, and rapid prototyping to test AI product and go-to-market assumptions.

Dec 2023 — present

Luxen LLC · Co-Founder

Leads product strategy and technical execution across AI agents, developer tools, automation, and research workflows. Converted 100+ user interviews into roadmap decisions, helped ship products to 5,000+ active users and 1.5M+ media views, and secured $48,000+ through programs including 1517 Fund, SoftBank, and BizWorld.
