Kaiwan taught himself BASIC programming on his Dad’s office IBM PC-XT when he was in the 9th grade (back in 1983). The urge to learn, hack and master at the level of the “bare-metal” was born there! After completing his B.E. in Information Science & Tech, he went to work (1991): helping build an antivirus product using assembly and C on a DOS platform. He thought DOS was awesome, until one fateful day he “discovered” the joys of UNIX! (from none other than Richard Steven’s iconic original “UNIX Network Programming” book and working on ‘C’ applications on SCO Unix). Many years later, working on the creative side (doing multimedia and web design), he “re-discovered” Free Unix on the PC – in the form of Linux of course. Kaiwan has plumbed the depths of the Linux system programming stack – right from mastering bash scripting, to system programming userspace with ‘C’, to deep OS-level kernel internals hacking and debugging. Along the way, he has worked on several commercial and opensource products and projects. His (opensource) contributions include device drivers for the mainline Linux OS, and several small self-founded projects hosted on GitHub. He is currently working on and looking to actively contribute in the Linux OS hardening and security space. His passion for Linux and actively programming on it by working on industry and opensource projects and products, feeds well into his other passion – for close to two decades now, Kaiwan has been teaching engineers the intricacies of the Linux OS, and how to design and implement code (for robustness and security). It doesn’t hurt that he is an ultra-marathoner too (several marathons, a few 50k’s and one memorable 100 km event).
