◾ Orchestrated and maintained a highly available Kubernetes cluster with Cilium networking, achieving secure application routing via Istio gateway, Cilium-Nginx ingress.◾ Deployed MongoDB, PostgreSQL-HA, Elasticsearch and Redis Cluster on kubernetes as statful and used NFS for PV and PVCs for those database.◾ Developed Terraform modules for Google Cloud Platform, streamlining VM provisioning, Cloud Storage, VPC, and utilized Ansible for efficient configuration management.◾ Implemented stable Data Pipeline from MySql CDC -> Kafka -> ELK & ScyllaDB CDC -> Kafka -> ELK. both Data coming into same index with help of routing feature in Elasticsearch Optimized Queries performance by 98% to get data in Web UI.◾ Research and Developed ScyllaDB Mulit-DC database Cluster setup and Automated Incremental backup of Data as well as Snapshots. With help of Cassandra Stress & Jmeter tools done load testing set benchmark to handle 1000+ Insert Queries per sec.◾ Enhanced system clarity by implementing Kafka for streaming Grafana alerts to MongoDB, resulting in a 95% reduction in alert complexity. Managed and maintained all databases, including backup and restoration.◾ Implemented a robust CI/CD pipeline for deploying 50-100 microservices on Kubernetes using Azure DevOps, Jenkins, SonarQube, and GitLab. ◾ Automated Everyday CDC source Connector creation for ScyllDB everyday Table creation using Python Code thus removed Manual Efforts of one person.◾ Built various monitoring dashboards for data Visualization in Kibana as well as Grafana using Aggregated Queries. GCP LB logs Queries to visualize each Clients hits on dashboard and monitored thus achieved clarity of application flow working by 95%.Implemented a comprehensive monitoring stack, including Grafana, Mimir, Loki, Tempo, and Otel, increasing system availability by 80% through timely alerts to respective teams.
