Some of my own apps include "0Password" (https://0password.co), a password-less system to keep all your passwords, “Ready” (https://readytheapp.com), a news reader, and "Sympho" an iOS game (https://digitalleaves.com/sympho/), among others. I am also a full stack javascript developer, with experience developing web apps from the backend (Node.js, Express, PHP...) to the frontend side. I am highly skilled in designing service-oriented RESTful APIs (in Node.js/PHP) and OAuth 2 authentication systems with an emphasis on security and cryptography. Current interests include Cryptocurrencies and the Blockchain, mobile Apps, RESTful APIs, secure, password-less authentication systems, and NoSQL database systems.
