Who you're hiring

For five years I've built and defended the platform at a healthcare software company, where security is a large part of my job. I'm also the security engineer for a B2B software startup, and I've found real vulnerabilities in widely used open-source code. I've built, shipped and sold my own software too, so I know what it's like when the app is your income. You work with me directly.
Across my professional security work, not App Locksmith alone. The clients are under NDA, so no names, ever — including yours.
