Arivazhagan Pandiyan

I am a seasoned Site Reliability Engineering Lead / Senior SRE with over 11 years of experience supporting large-scale production environments across financial services and logistics platforms. I specialize in building fault-tolerant, scalable infrastructure and ensuring operational excellence for mission-critical applications.

My expertise spans Microsoft Azure and Google Cloud Platform (GCP), with deep hands-on experience in Kubernetes (GKE) environments and enterprise observability platforms including Datadog (APM, Tracing, DBM, RUM), Splunk, and Dynatrace. I serve as the primary Datadog specialist, managing end-to-end observability pipelines and driving telemetry hygiene through OpenTelemetry adoption.

As an Incident Commander, I lead triage for high-severity outages and drive post-incident root cause analysis (RCA) to ensure continuous improvement. I've successfully reduced alert noise from 40% to 10% by implementing AI-driven alerting, Watchdog anomaly detection, and SLO-aligned monitoring standards based on the "Golden Signals" framework.

I'm proficient in Infrastructure as Code using Terraform and Ansible, with strong scripting skills in Python, PowerShell, and Shell. I hold the Microsoft Certified: Azure Administrator Associate (AZ‑104) and Datadog Fundamentals certifications. I'm passionate about reducing toil through automation, optimizing cloud costs, and mentoring engineering teams on observability best practices.
