About

Hi, I'm Sarah! I'm an early-career Software Engineer and Brown University alum. I graduted magna cum laude from Brown with an Sc.B. with Honors in Computer Science in 2026. At Brown, I earned a Senior Prize from the Department of Computer Science for my work as a teaching assistant and undergraduate researcher. My studies focused on systems and design, which guided my current passion for accessibility and privacy. I'm originally from Durham, North Carolina.

I believe in building systems and interfaces that prioritize the needs of users, particularly through accessible features and privacy-preserving guardrails.

Research

At Brown, I was part of the ETOS group led by Professor Malte Schwarzkopf, where I researched privacy and security for systems across several projects.

LLMMarshal

My senior honors thesis project, LLMMarshal, is an out-of-the-box conversation management system for LLM chatbots that prioritizes privacy, usability, and performance. This work is now part of a larger project at the SPACE lab at Boston University by my collaborator Kinan Dak Albab.

Sesame

Before LLMMarshal, I was a coauthor on Sesame: End to End Privacy Compliance with Policy Containers and Privacy Regions. This system uses the guarantees of the Rust type system to wrap user data in policies that restrict how developers access it. Sesame was accepted to SOSP 2024, and I travelled with the team to present the poster for the paper and support our PI's talk.

Professional

During my summers in college, I expanded my programming and design skills through technical internships. For summer 2025, I was a Software Engineer Intern at Microsoft. I interned on a frontend team where I used TypeScript and React to build new call control features for Microsoft Dynamics 365 Contact Center platform.

In the summer of 2024, I interned at Audible on a backend services team. My internship project focused on upgrading two pipelines to CI/CD by building integration test suites.

In 2023, I interned at Pearson on a Site Reliability team, where I first encoutered cloud computing and earned my AWS Cloud Practitioner Certification. For my project, I built a chatbot with access to proprietary data for Pearson employees.
