Fuzz Testing for Compiled Code

Overview

Designed and deployed an internal fuzz testing capability focused on compiled codebases (C/C++). Built fuzz harnesses with libFuzzer, integrated projects with OSS-Fuzz for scalable coverage, and leveraged Mayhem for automated bug discovery. Embedded fuzz testing into CI/CD pipelines and provided developer training on writing and extending fuzz harnesses.

Role

Director and lead security developer, authoring the initial harnesses and framework before transitioning operations to a managed partner.

Impact

Identified zero-day vulnerabilities pre-release, reduced production security defects by 30%, and equipped developers with reusable fuzz testing patterns.
