Cloud Infrastructure and DevOps Engineer February 2025 - Present

• Automated the provisioning of AWS EKS clusters using Terraform and deployed applications through CI/CD pipelines built with GitHub Actions, including secure OIDC authentication, AWS IAM permission management, and Docker image via ECR.

• Deployed a comprehensive observability stack integrating Grafana, Prometheus, Loki, and Kubecost to monitor application metrics (latency, throughput, HTTP codes), analyze infrastructure costs, and centralize logs via Fluent Bit, with persistent storage of metrics and logs on S3 for long-term archiving.

• Developed a proactive monitoring system with automated alerts sent to Microsoft Teams through webhooks, including tracking HTTP statuses and error messages to enable rapid incident resolution for websites and APIs.

• Implemented intelligent autoscaling with Karpenter on EKS to dynamically provision Kubernetes nodes aligned with workload demands, significantly reducing infrastructure costs.

• Configured a global content distribution network with CloudFront coupled with ACM for automated SSL certificates, enhancing web application performance and security.

• Automated the deployment of serverless Lambda functions triggered by EventBridge using GitHub Actions (CI/CD), ensuring reliable and reproducible event-driven workflows.

• Optimized database observability by configuring RDS PostgreSQL with automatic log export to CloudWatch, collected by Fluent Bit and centralized in Loki for advanced analysis, enabling detailed monitoring of performance and queries.

• Designed and deployed a conversational AI assistant based on AWS Bedrock to automate customer service, providing real-time access to business data (inventory, products, orders) for personalized and instant responses.
