After becoming an expert on intrusion detection, vulnerability, and public key cryptography for major banks like Centurion and ABN Amro Bank, Arul joined Apple. As part of Apple’s prestigious secret projects group, Arul helped invent the world's first smartphone – iPhone 1. On that initiative, he designed, developed, and implemented the security and activation platform cryptographically. He also developed a secure manufacturing environment that prevented the iPhone from being cryptographically attacked. Arul left Apple to join the startup world as CTO of Avot Media which he took from the proof-of-concept stage to a successful M&A. When Avot was acquired by Smith Micro, a developer and marketer of both enterprise and consumer-level software and services, Arul became director of the video and voice businesses. There, he built on-demand and live streaming capabilities for companies like Sprint and Warner Bros. Beyond his business acumen, Arul writes code in many languages – from the kernel-level code to Python.
