Sanskar Sinha

Senior DevOps Engineer with 5 years of experience architecting, automating, and operating scalable cloud-native infrastructure on AWS. Expertise spans Kubernetes (EKS), Docker, Terraform, Jenkins, and CI/CD pipeline design. Demonstrated track record of reducing deployment cycle times by up to 40%, improving system uptime to 99.9%, and eliminating infrastructure drift across enterprise environments.

Experienced in DevSecOps practices, incident management, and cross-functional delivery in regulated enterprise settings.

Senior DevOps Engineer at Tata Consultancy Services (TCS) (2023-01 – Present)

• Architected and led a release modernization initiative by redesigning Jenkins pipelines into parameterized, reusable stages (build, validation, approval, deploy, rollback), cutting manual release effort by 35% and reducing deployment failures across environments.
• Built a GitOps-based self-service deployment framework using Jenkins, ArgoCD, Git, and Shell scripting — enabling controlled hotfix and scheduled releases with approval gates, audit logs, and branch-based promotion logic.
• Standardization of the infrastructure with Terraform (IaC), provisioning and managing AWS resources (EC2, IAM, S3, VPC, Route 53), eliminating drift of the environment and reducing the time to configure the new environment by 50%.
• Improved Kubernetes / Amazon EKS deployment stability by resolving recurring pod restart loops, tuning liveness/readiness health probes, optimizing resource requests/limits, and standardizing rollout strategies for critical workloads.
• Implemented DevSecOps controls by integrating SonarQube code quality gates and HashiCorp Vault secret management into CI/CD pipelines, reducing security misconfigurations in production.
• Enhanced observability by building Prometheus + Grafana dashboards and CloudWatch alert runbooks, reducing Mean Time to Recovery (MTTR) by 35% and reducing repeated production incidents.
• Strengthened release governance by integrating deployment execution with ServiceNow change controls, enforcing approval checkpoints, evidence capture, and rollback traceability for regulated enterprise environments.
• Acted as the primary on-call engineer during major release windows — coordinating across application, infrastructure, and support teams and owning deployment decisions, rollback planning, and post-release validation.

DevOps Engineer at Tata Consultancy Services (TCS) (2021-11 – 2023-01)

• Designed and implemented end-to-end CI/CD pipelines using Jenkins and Git, automating build, test, and deployment workflows and reducing release cycle time by 40%.
• Containerized Java microservices with Docker and orchestrated deployments on Kubernetes (Amazon EKS), improving scalability and reducing deployment failures by 30%.
• Managed highly available AWS environments (EC2, ECS, ELB, Lambda, S3, VPC), maintaining 99.9% production uptime via Auto Scaling Groups and Elastic Load Balancers.
• Provisioned and managed AWS infrastructure using Terraform, reducing manual provisioning effort by 50% and ensuring consistent, repeatable environment builds.
• Contributed to serverless automation using AWS Lambda and Bash scripting for log cleanup, file handling, health checks, and operational support tasks.
• Enhanced security and compliance posture using CloudTrail audit logs and AWS Config rules for continuous governance and drift detection.
• Managed Git workflows, branching strategies, and pull request reviews, improving team code quality and release collaboration.
