I have been an Apple developer since the mid-80's currently developing applications for both iOS and Mac.

I started with PDP-11's, then DECSystem '10s and '20s.

My fields of experience are network protocols, hardware development, concurrency, and security. I worked with one of the leaders in security field in the late 80s.

My designs always incorporate security/privacy from the start. I am currently designing apps for medical providers.
