Jio Platforms Ltd
- Automated configuration management and security assessments across Linux servers using Ansible playbooks, cutting manual effort by 85% and increasing operational productivity by 90%.
- Deployed real-time infrastructure monitoring with Zabbix on Ubuntu servers and integrated Telegram-based alerting, reducing incident response time and sustaining ~99.9% service availability.
- Orchestrated containerized workloads with Docker Swarm across distributed production nodes, improving application scalability and reducing failed-deployment incidents.
- Built and maintained end-to-end CI/CD pipelines in Jenkins, reducing deployment time by 80% through automated build, test, and release workflows.
- Provisioned and managed multi-environment infrastructure as code with Terraform, enabling rapid, repeatable, version-controlled environment setup and cutting manual provisioning effort.
- Led infrastructure migration from on-premises to AWS and GCP, improving scalability and reliability, while driving the ongoing transition to Kubernetes-based container orchestration.
- Monitored real-time device health across 33M+ endpoints, processing ~75 billion heartbeat signals daily emitted every 30 minutes per device.
- Enhanced automation workflows toward zero-downtime operations by proactively identifying and resolving signal-reception dips across the device fleet, reducing missed-signal incidents.
- Partnered with development, QA, and infrastructure teams during incident response and release planning, contributing to root-cause analysis and observability improvements across high-volume, low-latency pipelines.
Projects
Watchify
View Project- Architected an end-to-end CI/CD + GitOps workflow for a 4-service microservices platform on AWS EKS, including Jenkins pipelines with shared libraries (DRY) for image builds, automated security gates (Trivy, OWASP Dependency-Check, SonarQube), and ArgoCD-driven continuous deployment.
- Engineered infrastructure including VPC, a private-networked EKS cluster, encrypted S3 storage, and IAM/IRSA roles, with Helm-managed AWS Load Balancer Controller for ALB ingress and SSL/TLS via Let's Encrypt.
- Authored reusable Kubernetes manifests with a MongoDB persistent volume, designed for easy scaling and new service onboarding.
- Implemented modular, multi-environment Terraform with remote state in S3 and DynamoDB locking.
