Background

About John Ojerahi

At the intersection of IT and operational infrastructure, I help keep Ireland’s water systems connected, secure, and reliable. As an Operational Technology Site Analyst at Irish Water, I work hands-on with telemetry integration, user access management, and emerging technologies like SD-WAN — all critical pieces that ensure essential services keep running smoothly for communities across the country. With a foundation in IT support and troubleshooting, I’ve always enjoyed turning complex challenges into practical, dependable solutions. I thrive where technology and operations meet, and I’m especially passionate about bridging the gap between IT and OT to improve resilience, efficiency, and service delivery on a national scale. Curiosity and continuous learning drive me. Whether it’s helping teams onboard to the National Telemetry System or supporting day-to-day OT operations at the National Operations Management Centre, I’m focused on making systems more dependable and building trust in the technology that keeps vital infrastructure going. At the end of the day, I believe great technical work isn’t just about fixing issues — it’s about empowering people, strengthening critical services, and making a real difference in how we live and work.
