Sandeep Reddy

About

Cloud/SRE-style engineer at TDS supporting revenue-critical transportation SaaS platforms on AWS/GCP with Kubernetes. Has hands-on experience leading high-impact production work including DDoS mitigation, zero-downtime MSSQL→PostgreSQL migration using CDC, and building secure GitHub Actions + ArgoCD delivery pipelines and Terraform-based GKE infrastructure.

Key Strengths

• Operates production SaaS infrastructure across AWS and GCP (Kubernetes, VMs, load balancers, managed databases)
• Built monitoring and anomaly detection on load balancer traffic (Prometheus/Grafana/Datadog) enabling rapid incident identification
• Led DDoS incident response: IP blocking, rate limiting, DNS reroute, backend isolation, and post-incident WAF hardening
• Designed and executed planned Kubernetes failover testing (node drain) validating pod rescheduling and no customer impact
• Led zero-downtime database migration from MSSQL to PostgreSQL using CDC replication with rollback planning and cutover monitoring
• Built secure GitHub Actions CI/CD for Java microservices to Kubernetes with ArgoCD, approvals, OIDC auth, and versioned rollbacks
• Diagnosed and fixed CI/CD deployment failures caused by expired registry auth tokens by implementing OIDC-based short-lived token refresh
• Implemented Terraform IaC for GKE/VPC/IAM/load balancers with reusable modules, remote state per environment, drift detection, and controlled prod rollouts

Reference Highlights

• Direct hands-on ownership of IBM Power production environments
• Composed and methodical under pressure
• Independently diagnoses and resolves critical production issues
• Minimizes downtime during live production troubleshooting
• Highly effective at restoring services quickly within SLA
• Drives RCAs to closure
• Improves operational maturity after incidents
• Strengthens runbooks to prevent recurrence
