Vishal tewatia

Architected and delivered a production multi-cloud Kubernetes platform for Mercer's assessment system, spanning AWS and Azure. Built and maintained reusable Terraform modules to provision Amazon EKS, Azure AKS, Redis, PostgreSQL, VPC/VNet networking, and DNS, enabling repeatable, isolated infrastructure deployments across cloud providers. Designed Kubernetes ingress and security architecture: AWS ALB Controller and Azure Application Gateway Ingress Controller for L7 routing, WAF integration for external traffic, and automated TLS lifecycle management via cert-manager. Implemented GitOps-based application delivery using ArgoCD, enabling declarative, auditable deployments across all Kubernetes workloads. Built end-to-end CI/CD pipelines for Terraform with isolated environment layers, automated plan/apply workflows, and safe rollback mechanisms, reducing deployment risk across multi-cloud environments. Established monitoring and observability stack using Prometheus and Grafana, providing visibility into cluster health, resource utilization, and application performance.

Built and owned a self-service CI/CD platform supporting thousands of developers across hundreds of microservices, running in 67 environments each with 4 Kubernetes clusters. Architected the CI/CD platform from the ground up, designing pipeline standards, environment promotion workflows, and integrated testing stages that enabled automated deployments at enterprise scale. Owned end-to-end release management for the platform, building a custom release pipeline using Brigade.js to coordinate versioning, artifact promotion, and deployment sequencing across all environments. Developed custom CI/CD tooling in Go to extend platform capabilities and reduce manual intervention; worked across GitHub Actions, CircleCI, and Jenkins to standardise pipeline patterns across teams. Integrated SonarQube for automated code quality gates and Sonatype Nexus for artifact management, ensuring consistent quality enforcement across all pipelines. Owned platform reliability end to end: triaged incidents, resolved pipeline failures, and continuously shipped improvements aligned with evolving business needs. Mentored new joiners and trained freshers on platform tooling, CI/CD workflows, and DevOps practices, helping onboard team members to a complex multi-environment setup.
