Nikolai Lifanov hacks systems. This means doing things that aren't meant to be done to create a useful effect in a hurry. Over the last decade, he has had experience in everything from running HA infrastructures on donated prefail hardware to dealing with emergency spikes in service demand by padding the infrastructure with cloud services within hours. He had roles ranging from that of a full-stack engineer to a developer, but feels most in his element focusing on essential system infrastructure. He builds robust and observable systems that are hard to break and easy to fix with a strong focus on self-healing, security, and reducing essential ongoing maintenance. He has built solutions from Linux and BSD systems, from creating immutable live cd NetBSD hypervisors (a la SmartOS) to founding a hosting business based on DragonFly. He tries to be active in the open source community and enjoys old-school roguelike games. His hobbies include researching obscure ancient arcane Unix lore and retro computing.
