About
DevOps/SRE with eleven years of experience in Application Support and Operations, gradually developing towards AI-driven Software Development. Solid knowledge of how modern computer systems work (and how they don't), extensive Linux and network administration experience, a sound understanding of Computer Science concepts, and plenty of enthusiasm for bringing DevOps and SRE practices into reality. Looking for an opportunity to gang up with bright, seasoned folks passionate about their work — and add all my skills, wisdom, and zeal to the heap.
