I’m a DevOps engineer with hands-on ownership of cloud infrastructure and large-scale data orchestration across AWS, Azure, and GCP. My day-to-day work spans Kubernetes (EKS/AKS/GKE), Terraform, ArgoCD, CI/CD, Apache Airflow, and Snowflake—built for stability in real production environments.

At Infra360 (cloud & DevOps consulting), I embed with senior data, MLOps, and data platform engineers and deliver end-to-end cloud migrations. I executed an in-place Apache Airflow 2.10 to 3.2 upgrade across AWS EKS and Azure AKS, preserving metadata with backup/rollback runbooks per cutover.

I also root-caused a production Airflow 3.1.7 DagProcessor crash loop, traced to a heartbeat/liveness-probe mismatch under memory pressure, and tuned probes/resources to drive a permanent framework upgrade. Beyond that, I automated Snowflake RBAC as Terraform across four cloud-region repositories, integrated Microsoft Entra ID SSO over OAuth 2.0, and hardened scaled API replicas, worker OOM behavior, and Postgres connection-pool exhaustion.

I replicate production into isolated multi-region GCP tenants for data residency and latency (US and Middle East), provisioning VPC/networking, autoscaling private GKE, GeoDNS failover, CDN-backed GCS, and Cloud KMS-encrypted remote state via Terraform. I build GitOps and observability/security foundations with ArgoCD ApplicationSets, Helm/ Istio, Prometheus/Grafana/Mimir, and scanners like Falco, ELK, Trivy, Snyk, and OWASP ZAP—while staying active in open source (MLflow, CNCF Kubernetes Conformance, Apache Airflow) and writing production-focused DevOps/MLOps content on my blog.
