Installed, configured, and managed the (OpenSearch Search, Log stash and Kibana) for Log management within EC2 for Open Search. Worked with Logstash to visualize key Open stack environment log metrics on Kibana (ELK).Designed and executed integration strategies, mapping Splunk functionalities to OpenSearch to maintain or enhance existing capabilities and implemented connectors or pipelines to ingest logs and other data sources into OpenSearch for analysis.Led the migration initiative from Splunk to ElasticSearch for log management and analytics, ensuring a smooth transition and oversaw data migration processes, ensuring data integrity and minimal disruption.Designed and developed intuitive dashboards in Grafana to visualize complex data sets and metrics and customized visualizations and panels to provide actionable insights for stakeholders.Designed and managed HPC clusters with optimized CPU/GPU resource allocation for scientific computing and data-intensive workloads and leveraged AWS HPC environments with EC2 instances and Parallel Cluster to dynamically scale workloads.Developed custom APIs using Python and Node.js that leveraged DSL for dynamic search queries and integrated DSL-based search functionalities with Kibana dashboards and Angular web interfaces for interactive analytics.Created and deleted a collection of resources together as a single unit (stack) using AWS CDK. Created IAC solutions through AWS CDK, AWS CloudFormation, AWS CLI, or Terraform leveraging configuration management solutions such as Ansible or PowerShell.Configured CloudWatch Events rules to filter and process GuardDuty findings and used a durable storage solution to store the timestamp or identifier of the last successfully processed event.Established FinOps best practices across cross-functional teams to align cloud spending with business objectives and leveraged AWS Cost Explorer with setting up CloudWatch alarms and AWS Budgets to trigger alerts on anomalous spending.
