Implemented Infrastructure as Code (IaC) using Terraform and Terragrunt to manage AWS and MongoDB Atlas resources, improving consistency and reproducibility across environments. Managed four Kubernetes clusters (development, production, GitLab runners, and shared services) to support multi-environment workloads and cross-cluster integrations. Administered PostgreSQL multi-AZ instances, developed outage response plans, and enhanced visibility through CloudWatch and Datadog dashboards and alerts. Deployed and maintained Kafka clusters and connectors, ensuring reliable messaging and data streaming pipelines. Migrated unmanaged AWS resources into Terragrunt state, and refactored existing Terraform states to improve governance and scalability. Automated MongoDB Atlas cluster and network configuration through Terragrunt and Terraform. Hardened application security by implementing and maintaining AWS WAF rules. Developed and contributed to reusable Terraform modules for key AWS services including CloudFront, CloudTrail, CloudWatch, IAM, VPC, S3, SES, Security Groups, and OpenSearch, improving deployment standardization. Enhanced monitoring and observability with Datadog by building dashboards to visualize pod resource consumption and creating alerting for service outages, RDS disk usage, and abnormal web traffic on critical endpoints. Maintained and debugged Kubernetes clusters, improving reliability and reducing downtime. Implemented CI/CD pipelines using GitLab CI and ArgoCD for automated testing and deployments. Managed Helm charts for all microservices across environments. Secured application and service secrets via HashiCorp Vault. Patched security vulnerabilities identified through the Orca Security platform. Reduced AWS infrastructure costs by 20–25% through optimization initiatives including rightsizing, improved monitoring, and architectural adjustments. Migrated core microservices to distroless Docker images, minimizing attack surfaces and enhancing service security.

Built AWS infrastructure from the ground up to support a full-stack web application, implementing Infrastructure as Code (IaC) with Terraform for scalable, reproducible deployments. Managed and automated key AWS services including EC2, ECS (Fargate), ECR, VPC, S3, RDS, DMS, and CloudWatch. Executed data migration pipelines using AWS DMS between MSSQL engines, eliminating the need for custom ETL scripts and significantly reducing migration time. Developed ECS Fargate clusters leveraging Docker images from ECR, improving deployment consistency and reducing operational overhead. Configured centralized monitoring and alerting with CloudWatch, integrating with Slack to notify teams of downtime or abnormal resource utilization. Designed and deployed multi-region AWS infrastructure to enhance availability, resilience, and user experience across geographic regions using AWS Global Accelerator.

Implemented Infrastructure as Code (IaC) with Terraform to manage AWS services including EC2, EKS, VPC, and S3, ensuring consistency and scalability across environments. Automated snapshots and disaster recovery by scheduling periodic EBS and RDS backups, and configuring PostgreSQL master–replica setups for high availability. Configured EC2 Auto Scaling Groups (ASG) to optimize resource utilization and maintain performance under variable workloads. Designed secure network architectures by separating public and private subnets and enforcing least-privilege security group policies for EC2 and RDS instances. Created pre-configured Linux AMIs using Packer and Bash scripts, reducing EC2 provisioning time and improving deployment speed. Implemented monitoring and alerting systems with Grafana, Prometheus, and Elasticsearch, providing visibility into system performance and reliability. Deployed and maintained containerized applications across multiple Kubernetes clusters using Helm, supporting over 30 applications running on EC2 and RDS infrastructure. Deployed and managed Kafka and Zookeeper clusters, ensuring stable message streaming and system communication. Streamlined CI/CD processes with GitLab CI, introducing conditional pipeline execution to maintain CI agent availability and reduce unnecessary workloads.

Configured and maintained CI/CD agents with Buildkite, automating build and deployment pipelines for reliability and scalability. Developed Buildkite job scripts using Bash, streamlining workflows and reducing manual steps during application deployments. Managed AWS infrastructure including EC2 (Linux), S3, CloudFront, Route 53, RDS, ECR, and Elastic Beanstalk, ensuring security, performance, and scalability. Reduced AWS costs by approximately 25% through automated scheduling of non-production resources and cleanup of idle instances. Containerized applications using Docker, enabling consistent builds and faster deployments across environments. Deployed Kubernetes clusters and workloads with kOps and Helm, improving scalability and resource orchestration. Implemented configuration management with Ansible, automating provisioning and deployment of bastion hosts and application instances (Glee2). Adopted Infrastructure as Code (IaC) with Terraform, replacing Elastic Beanstalk environments with a modular, boilerplate Terraform AWS template, simplifying infrastructure management and deployments.

Provided technical and event support, ensuring smooth classroom operations and prompt issue resolution. Developed a Java-based notification application to support real-time alerts in classrooms.
