Real-World Observability Lessons from Nexi Group

At Observability Sessions Stockholm, Roman, Principal Architect for Nordics Online & Merchant Solutions at Nexi Group — one of Europe’s largest payment technology companies — spoke candidly about what it takes to build and scale an observability culture inside a large, complex organisation. He covered how his team moved from manual dashboard and log review to AI-agent-led investigation, how discovering Adaptive Telemetry saved the team from a runaway spend commit, how a single shared Grafana Cloud platform broke down silos between development teams using different technology stacks, and what it really means to shift engineers from reactive to proactive incident ownership. His parting advice: hire a seasoned SRE.
