Hi there 👋

LinkedIn Email GitHub

I'm a Cloud Support Engineer (DevOps) with expertise in AWS, Kubernetes, and Infrastructure as Code. I am interested in automating infrastructure at scale, and creating self-service solutions that enable teams to deploy faster and more reliably.

🔭 Currently Working On

  • Enhancing spotter with Kubernetes-native pod scheduling optimization
  • Contributing to open-source CDK

🚀 Featured Projects

Platform Engineering

Production-grade spot instance scheduling system for EKS worker nodes. Intelligently finds the cheapest ARM64 spot instances across availability zones, handles spot interruptions gracefully, and maintains cluster capacity with smart fallback mechanisms.

Tech Stack: AWS CDK, Lambda, EventBridge, EKS, CloudFormation, Kubernetes
Key Features: 70-80% cost savings, multi-AZ optimization, intelligent interruption handling, ARM64 focus

Complete RDS migration solution demonstrating the transition from Aurora Serverless v1 to v2 using AWS CDK. Includes infrastructure provisioning, data migration strategies, and rollback procedures.

Tech Stack: AWS CDK, RDS Aurora, Lambda, CloudFormation
Key Features: Zero-downtime migration, automated rollback, cost optimization

A static website that displays current AWS EC2 Linux On-Demand pricing information across multiple regions. The site is automatically updated weekly using AWS CodeBuild and EventBridge scheduling.

Tech Stack: Python, GitHub Pages, AWS CodeBuild, EventBridge
Key Features: Automated weekly updates, multi-region pricing data, serverless automation

Python Packages & CLI Tools
