About

Services developer with a strong focus on security, service health, and solving complex problems with the most understandable and reusable code. I've developed large-scale web services to support the engineering systems of companies as large as Microsoft, contributed to major open-source projects, and reported significant security vulnerabilities in various software. I believe in iterative improvement (of both product and self), collaboration, and eschewing the traditional programming interview in favor of real-world problem solving. Along with hiring, I also think that teaching is one of the hardest - yet most important - skills.
