/ HOW I WORK

Engineering for reliability, not just deployment.

I focus on building cloud environments that are reliable, secure, and easy to maintain. I look for ways to simplify repetitive tasks, make deployments more predictable, and identify issues before they affect operations. My goal is to reduce manual effort, improve reliability, and make everyday infrastructure management more efficient.

Senior Research Associate

Managed production AWS environments across 10+ accounts, including an account running 3-4 EKS clusters across development, staging, and production. Supported on-call operations, consistently met the 30-45-minute P1 resolution target, and performed root cause analysis (RCA).
Reduced monthly AWS spend by 20–30% through Well-Architected reviews across 10+ accounts, unused resource cleanup, backup and retention optimization, Reserved Instances and Savings Plans, and upgrades that avoid extended support charges. Remediated IAM, GuardDuty, and Trusted Advisor findings to strengthen security and governance.
Planned and executed EKS cluster and managed node group upgrades across development, staging, and production. Configured and troubleshot Karpenter, VPC CNI, AWS Load Balancer Controller, EKS Pod Identity, and Kubernetes workloads, coordinating maintenance windows and post-upgrade validation.
Restored service within approximately 1-1.5 hours during an incident involving increased API load, storage exhaustion, and an RDS backup failure. Authored the RCA and implemented preventive controls, including storage monitoring, backup and retention improvements, and database alerts for connections, availability, latency, and long-running queries.
Automated IAM hygiene checks across AWS Organizations accounts to identify inactive users, unused access keys, and excessive permissions. Applied least-privilege access controls across AWS and Azure environments.
Developed Python (Boto3) and AWS Lambda automation for S3 object replication, EventBridge-scheduled synchronization of third-party provider IP ranges into security group prefix lists. Automated Azure VM credential rotation using AWS Secrets Manager.
Maintained and troubleshot deployment pipelines across AWS CodePipeline/CodeBuild, and Jenkins. Mentored 4-5 engineers in production troubleshooting and incident resolution, enabling them to handle issues more independently.
Executed tenant-to-tenant Azure migrations with less than two hours of downtime, maintaining data integrity and compliance requirements.

Research Associate

Developed reusable Terraform modules for network, EKS, and compute infrastructure, using Amazon S3 for remote state management and CI/CD pipelines for deployments.
Automated after-hours scale-down and scale-up of EKS managed node groups using AWS Lambda and EventBridge Scheduler, maintaining a minimum of one node to balance cost and availability. Reduced monthly EKS compute costs by 10-15% and eliminated 1 hour of daily manual effort.
Automated EC2 and RDS operations using Lambda scheduling, CloudWatch status-check alarms, stop/start recovery workflows, and Amazon Data Lifecycle Manager EBS snapshots, supporting environments operating under a 99.9% uptime SLA.
Conducted cost analyses for 10+ AWS and Azure clients using AWS Cost Explorer, Trusted Advisor, Compute Optimizer, and Azure Cost Management to identify cost-saving opportunities and recommend cloud resource optimization.
Deployed Azure Virtual Machine Scale Sets behind a Standard Load Balancer across multiple availability zones and implemented rolling VM image upgrades without service disruption.
