Migrated 3 production clusters (80+ microservices) from GCP GKE to Azure AKS with a maximum downtime of 3 minutes using a zero-downtime cutover strategy, migrating the production PostgreSQL database in parallel and saving over $1,000/month in recurring costs.

Self-Hosted Kubernetes Infrastructure: Built and configured a self-hosted Kubernetes cluster from scratch using kubeadm, managing core components including TLS certificates, etcd, API server, controller manager, scheduler, CNI, and kubelet. Network Automation & Deployment: Developed and deployed Java microservices on the cluster to automate data center router configuration workflows.

Serverless Architecture & Cloud Management: Designed and built a serverless dashboard managing 1,000+ cloud licenses, significantly enhancing IT infrastructure visibility and control. Performance & Cost Optimization: Cut backend operational costs by 40% and improved response times/performance by 35% using AWS Lambda, API Gateway, and DynamoDB.

Docker Container Optimization: Streamlined Docker containers using multi-stage builds and resource tuning, reducing image sizes by 45% and accelerating deployment speed by 30%. CI/CD Pipeline Enhancement (Jenkins): Optimized Jenkins CI/CD pipelines, cutting build times by 25% and significantly improving stability and reliability across different environments.

Full-Stack Application Development: Built a full-stack application tracking 1,500+ startups with real-time interactive dashboards. Data Extraction Automation: Automated data extraction from PDF files, reducing manual overhead and processing time by 85%. Kubernetes Infrastructure (AWS EKS): Deployed and auto-scaled workloads on Amazon EKS for 50 users, maintaining 95%+ service availability. CI/CD Pipeline Optimization: Streamlined Jenkins CI/CD pipelines, accelerating application deployments by 30%.
