Azure, Kubernetes Managed 100+ production namespaces on AKS, with Azure Application Load Balancers, Azure DNS and Traefik ingress Built Jenkins CI/CD pipelines for React and Express.js apps Set up Prometheus, Grafana and Slack alerting, and OpenCost for CPU, memory, volume and network cost analysis Wrote shell and Python automation for PostgreSQL provisioning and chunked, resumable database migrations Deployed OCR engines (Tesseract, EasyOCR, Paddle, TrOCR) and LLMs (LLaMA 3.x, LLaVA, CodeLLaMA, Mistral-7B) for document processing Achieved 99.9% uptime through proactive monitoring Secure Enterprise AI Platform: Private-Network Azure Deployment Infrastructure: Provisioned the full Azure environment for an AI application to match a regulated client's security requirements, using Terraform and GitHub Actions Designed isolated private VNets for UAT and Production. Provisioned PostgreSQL, Redis, Service Bus, Storage Account and MongoDB Atlas, all behind Private Endpoints. Also deployed self-hosted Neo4j on a dedicated VM Configured NSG rules and firewall approvals for App Services and the private AKS cluster Fixed private endpoint and private AKS endpoint resolution with Terraform-managed central DNS A records Access control & DNS: Enforced IP-allowlist access on App Services and AKS ingress, so public requests return 403 and the apps are reachable only over VPN custom domains and SSL: alias and TXT records for App Services, and DNS A records with cert issuers in ingress for AKS Secure CI/CD (Azure Pipelines + JFrog): UAT deploys automatically on dev-branch commits. Production deploys manually after change-request approval Images are built and pushed to JFrog, then vulnerability-scanned. Any image with findings fails the pipeline, and clean images are promoted from JFrog central to edge Dockerfiles use only approved JFrog repositories, with no public libraries Frontends deploy by updating the image tag and restarting App Services. The backends deploy to AKS via Helm
