Abdur Razzaq Siddiqui

I’m an experienced DevOps Engineer building high-availability, cloud-native infrastructure across on-prem and major cloud platforms. I deploy and manage Kubernetes clusters for production-grade workloads—including 4-node Kubernetes setups (on-prem with HAProxy and Keepalived, and Azure AKS with Load Balancer) for a 23-microservice platform using Kustomize.

I drive resilience and faster deployments by implementing multi-master Kubernetes (6 nodes: 3 masters and 3 workers) with HAProxy & Keepalived for minimal-to-no downtime, plus Redis Sentinel failover for Redis high availability. I also R&D and deploy Kafka (KRaft) Confluent clusters to support HA messaging, and streamline delivery through containerization, CI/CD workflows, and automated deployment practices using Docker and cloud infrastructure on Azure. Beyond ops, I’ve built full-stack web apps and microservices with Flask, React.js, Node.js, and FastAPI, and created projects like a Resume - Job Compatibility Checker using Python and NLP techniques.
