Guy Ndjanda

Bilingual (English/French) Observability Specialist with 8+ years of hands-on Application Performance Management experience across AppDynamics, Dynatrace, Instana, New Relic, and Turbonomic, backed by 20+ years of enterprise technology experience.

Proven track record in defining enterprise observability strategies, leading complex multi platform implementations, and driving measurable improvements in MTTR, platform adoption, and monitoring maturity across multiple industries.

Currently serving as a CSM Architect at IBM, acting as a technical value advisor and senior escalation point for large-scale observability deployments. I translate complex distributed system telemetry into actionable business outcomes and champion AIOps, Kubernetes native monitoring, and cloud observability modernisation. Equally effective as a hands-on practitioner and a strategic advisor to C suite, engineering leadership, and DevOps/SRE teams.
