Ritej Anil Mule
Infrastructure that heals itself.

I build the pipelines, clusters and guardrails behind payment-grade systems on AWS: Terraform-modelled infrastructure, EKS and ECS delivery, zero-downtime releases and observability that cuts time-to-detect. Then I turned that experience into a place to practise it.

Production work, in order

DevOps Engineer · Techpaylogic Technologies Pvt. Ltd.

June 2026 – Present · Navi Mumbai

Owns production deployment and infrastructure availability for PayLogic (payment gateway API) and Travolocity (travel platform).

  • Zero-downtime releases: canary and blue/green on AWS ECS, ALB weighted routing and Jenkins; rollback time cut from 20 min to under 2 min.
  • Terraform modules for custom VPCs, multi-AZ subnets, NAT gateways, EC2, RDS (PostgreSQL/MySQL) and ElastiCache across dev, staging and production.
  • Hardening: AWS WAF, Security Groups, NACLs, least-privilege IAM; ACM and Let's Encrypt certificate rotation.
  • Incident response: Prometheus, Grafana, CloudWatch and PagerDuty; MTTR reduced by 35%.

Things I built and shipped

Self-Healing AI Infrastructure

RandomForest model predicts failures from CPU/memory metrics; an auto-healer polls every 30s and restarts or scales above 75% failure probability. 58 Terraform resources on EKS (ap-south-1); MTTR from 30 min to 30 s.

EKSTerraformscikit-learnPrometheus

Three-Tier DevSecOps on EKS

Terraform provisions Jenkins and EKS; Jenkins pipelines build backend and frontend; ArgoCD delivers GitOps deployments; Prometheus and Grafana monitor.
