The best imitation of myself.

Zachary Waldowski

Mobile Software Engineer


I’m a passionate, perfectionist, sometimes angry developer with a decade of experience bringing uncompromising excellence to app platforms. As a technical leader, I advise and elevate team members at all experience levels, promote best practices like internationalization and accessibility, and focus intensely on quality. I am remembered for “seriously scary” recall of years-past details, framework pitfalls, and hard-won fixes.

I have worked with really obscure clients that nobody knows about. Rarely, I break software in public rather than in private.
