Project: Vahana Run Time (VRT) Automation

• Automated the entire VRT infrastructure setup for seamless deployment and scalability.
• Provisioned AWS resources including VPC, EKS, EFS, RDS, ElastiCache, and managed Node Groups with full automation.
• Integrated Cluster Autoscaler for dynamic scaling of Kubernetes clusters and mounted EFS storage across services.
• Automated the creation of namespaces, directory structures, and granted necessary permissions in ECR for application deployment.
• Implemented the installation of tools such as Prometheus, Grafana, and other monitoring utilities using Helm.
• Automated the deployment of microservices and infrastructure components, including the creation of ALB/NLB load balancers.
• Mapped DNS with the load balancer to newly created domain names, ensuring smooth traffic flow and availability.
• Developed and deployed multiple infrastructure environments with varying scales to meet diverse project requirements.

This project ensured a fully automated, scalable, and reliable infrastructure ready for deployment, significantly reducing manual intervention and enhancing operational efficiency.

Project: Saarathi

• Contributed to architectural decisions, ensuring scalable and maintainable designs for future expansions of application services.
• Increased system reliability, minimizing downtime and service disruptions through proactive troubleshooting and root cause analysis.
• Standardized development environments using containerization technologies like Docker, resulting in consistent deployments across various platforms.
• Developed continuous improvements and implemented solutions to existing infrastructure, tools and processes.
• Provided engineering support from code delivery until retirement of application.
• Maintained systems that monitored applications and infrastructure.
• Reduced deployment times with the introduction of CI/CD pipelines for multiple projects.

Project: Vahana

• S3 Migration: Migrated VFlow builds from Docker containers to an S3 bucket, improving reliability and reducing server costs.
• Security Enhancements: Led the resolution of security vulnerabilities for IndusInd Bank’s Docker images and implemented Vahana 2.0 security measures, including VAPT activities, applying security headers, and enforcing CORS policies.
• Infrastructure & Cost Optimization: Managed the scaling down of non-production environments, optimizing server usage, and reducing infrastructure costs by approximately $10,000.
• Service Monitoring & Automation: Developed a real-time service monitoring utility for Consul with automated alerts, ensuring service availability.
• Kubernetes & Docker Expertise: Led a POC on Kubernetes pod lifecycle management and custom Docker image creation, enhancing security and reducing image sizes.
• Consul Performance Fixes: Improved Vahana 2.0 performance by optimizing Consul service registration, addressing backend application property gaps.
• Deployment Strategy & Tooling: Devised a cost-efficient deployment strategy using on-demand and spot servers, and transitioned tool deployments to the organization’s GitLab repository for enhanced version control.
• Team Leadership & Knowledge Transfer: Solely managed Vahana 2.0 non-production environments, onboarded new team members, and provided guidance on infrastructure components, including Elasticsearch, Kafka, Zookeeper, Nginx, and Consul upgrades.
