About Sagar Srivastava

I am an AWS DevOps Engineer with 4+ years of experience designing, automating, and managing multi-cloud infrastructure across AWS. I focus on building secure, scalable, and cost-efficient platforms that bridge the gap between development and operations through automation, observability, and reliability.My expertise covers the entire DevOps lifecycle — from Infrastructure as Code (IaC) and CI/CD automation to containerization, monitoring, and DevSecOps integration. I design repeatable infrastructure using Terraform, Ansible and CloudFormation ensuring consistency and compliance across cloud environments. By leveraging GitHub Actions and GitLab CI/CD, I deliver automated pipelines that accelerate software releases and reduce manual effort by over 40 percent.I am proficient in Docker and Kubernetes (EKS) for container orchestration, using Helm for version-controlled deployments and zero-downtime updates. My work with Prometheus, Grafana and AWS CloudWatch provides real-time visibility and has improved system uptime to 99.9 percent while cutting mean-time-to-resolution by 25 percent. Security remains central to my approach: I integrate SonarQube, Veracode, and secrets-management tools to embed DevSecOps checks directly into every pipeline stage.In my current role at Tata Consultancy Services, I have supported Barclays Investment Bank under the BFSI domain, automating CI/CD workflows, containerizing legacy applications, and introducing cost-optimization through CloudOps automation. These initiatives delivered faster release cycles, improved audit readiness, and measurable cost savings of 25 percent.Technically fluent in Python and Bash, I develop custom automation scripts for provisioning, monitoring, and cost governance. Working in Agile/Scrum environments, I collaborate across development, QA, and infrastructure teams using Jira, Confluence, and ServiceNow to ensure continuous delivery and transparent communication.Recognized with TCS Star of the Month and On-the-Spot Award (2023), I am committed to continuous learning and innovation in cloud and automation. I believe DevOps is not just about tools but about creating a culture of reliability, collaboration, and continuous improvement. My goal is to build intelligent, self-healing systems that empower organizations to innovate faster, operate securely, and scale confidently in the cloud era.

   Project: Hybrid Cloud CI/CD Automation & Infrastructure OptimizationClient: Barclays Investment Bank (BFSI Domain)Organization: Tata Consultancy Services Ltd.Duration: Dec 2021 – PresentRole: AWS DevOps EngineerI worked on the automation and modernization of DevOps workflows for Barclays Investment Bank, focusing on hybrid cloud environments across AWS. The goal was to build a unified DevOps platform that improves deployment speed, scalability, and compliance while reducing operational overhead.I designed and implemented end-to-end CI/CD pipelines using GitHub Actions and AWS DevOps, automating build, testing, and multi-environment deployments. Infrastructure provisioning was automated with Terraform and Ansible, reducing setup time by 60% and ensuring configuration consistency across all environments.Applications were containerized using Docker and deployed on Kubernetes (EKS) with Helm charts to enable seamless, zero-downtime rollouts. I also integrated SonarQube and Veracode into pipelines to establish DevSecOps controls, reducing post-release vulnerabilities by 25%.To strengthen reliability, I implemented Prometheus, Grafana, AWS CloudWatch, and Azure Monitor for observability, improving uptime to 99.9% and reducing MTTR by 25%. Additionally, I automated CloudOps workflows using Python and Bash scripts, optimizing cost and achieving 25% savings through automated scaling and cleanup.Working in an Agile/Scrum environment, I collaborated with cross-functional teams using Jira and Confluence to manage releases and change requests. My contributions helped shorten release cycles by 40%, improve platform stability, and strengthen compliance for highly regulated BFSI workloads.
