# About Brett Haas

> I’m a software engineer in Bellevue, Washington, building ambitious products across AI, web, mobile, and intelligent systems.

## Focus

My work sits where dependable product engineering meets applied AI research: shipping cross-platform mobile and cloud software, red-teaming and evaluating frontier language models, and studying how inference-time interventions change model behavior without retraining.

## Education

B.S. in Computer Science, University of Virginia (Charlottesville, VA), May 2026. Focus areas: Computer Science, Cybersecurity, Machine Learning, and Software Engineering.

## Experience

- ML Research Assistant, University of Virginia, Nov 2025 – May 2026. Inference-time activation-steering research focused on language-model visual bias.
- GenAI Technical Advisor Intern (SEAL), Scale AI, Jun 2025 – Dec 2025. Frontier-model safety, evaluation, and agent reliability work on the Scale AI SEAL team.
- Software Engineer Intern, Refraction Innovation Hub, Jun 2025 – Aug 2025. Cross-platform nutrition and food-recognition product development across mobile, AI, and cloud systems.
