About

👋 Hi, I’m a Senior Network Operations Engineer (Site Reliability Developer) at Oracle in Dublin, where I help keep GPU infrastructure running smoothly while automating processes to make systems more reliable and efficient. I’m also actively learning data center technologies, exploring the inner workings of modern infrastructure and applying automation to streamline operations. Before Oracle, I spent several years at Cisco as a Technical Consulting Engineer, solving networking puzzles, supporting customers through complex issues, and working with technologies like Core Architecture (CATS), Routing Protocols, and SD-WAN. Troubleshooting, optimizing performance, and building scalable solutions have always been at the heart of my work. I enjoy bridging hands-on operations with automation, and if you’re passionate about infrastructure reliability, GPU systems, data center tech, or automating processes to make life easier, let’s connect!
