Senior Manager - DevOps
July 2022 - Present
Bangalore
Led a team of 9+ DevOps engineers to design and implement a multi-cloud strategy, reducing infrastructure costs by 25% and improving system reliability. Spearheaded the migration of 50+ microservices to Kubernetes, achieving 99.99% uptime and reducing deployment times by 40%.
Designed and automated CI/CD pipelines using Jenkins and GitLab CI, enabling zero- downtime deployments and reducing release cycles from weeks to hours. Implemented Infrastructure as Code (IaC) using Terraform and Ansible, reducing manual errors and improving deployment consistency. Established monitoring and alerting systems using Prometheus and Grafana, reducing incident response times by 30%.
Designed infrastructure on Google Cloud (BigQuery) for efficient ML lifecycle management.
Scrum Master Roles: 1. Implement Project Management/Best Practices 2. Keep all Parties on Track and Informed 3. Introduce Agile Engineering Practices 4. Coach Team Members 5. Host Daily Stand-up Meetings 6. Assist the Product Owner with the Product Backlog 7. Remove Roadblocks 8. Teach Scrum Practices and Principles. Increased operational efficiency with the implementation of containerization technologies and microservices architecture.
Implemented cloud strategies with AWS, Azure, and GCP, enhancing scalability and cost-effectiveness for production environments.
Integrated DevSecOps practices into DevOps workflows, improving system security and compliance with industry standards
Azure Copilot for Developers: By providing developers with Azure Copilot, you're not just improving coding efficiency; you're also enabling them to write better, more secure, and more maintainable code from the start. This proactive approach reduces technical debt and speeds up development cycles.
AI-Powered Code Quality Checks: Integrating Generative AI into your code quality checks automates and enhances the review process. This allows you to catch complex bugs, potential security vulnerabilities, and code smells that traditional linters might miss, ensuring higher quality software is deployed faster. Automating Day-to-Day Work: Using AI to automate routine tasks is a core principle of DevOps. This frees up your team from repetitive manual work, allowing them to focus on more strategic, high-value tasks like designing new architectures, improving system reliability, and innovating. This directly boosts team morale and productivity. AI for Issue Resolution: Leveraging AI to fix issues with a lower resolution time and meet SLAs is a major win. AI can analyze logs, identify root causes, and even suggest or apply fixes automatically. This minimizes downtime, improves system reliability, and allows your team to be more responsive to critical incidents. Integrated SAST, DAST, and container scanning tools into CI/CD. Led SOC 1 and CIS compliance efforts, improving audit readiness. Defined SLAs/SLOs, automated incident detection, and set up on-call response playbooks.
