Featured Projects
A showcase of my recent work in cloud infrastructure, monitoring, and FinOps automation.
AWS Infrastructure Monitoring System
Designed and implemented an AWS monitoring solution for EC2, RDS, S3, and ALB, generating automated daily health reports.
- ▹Leveraged CloudWatch and EventBridge to collect performance metrics and automate monitoring workflows.
- ▹Configured YAML-based multi-database monitoring with email notifications for proactive incident detection.
FinOps Assistant
Developed a FinOps chatbot using Chainlit and AWS MCP servers, integrating Cost Explorer APIs to provide conversational access to cloud cost insights and chargeback analysis.
- ▹Integrated AWS Cost Explorer APIs to provide service-level spend analysis, historical cost comparisons, and internal chargeback visibility.
Automated Website Monitoring & Alerting
Built a monitoring stack using Prometheus, Grafana, Blackbox Exporter, and Alertmanager to track website availability and service health.
- ▹Configured alerting integrations with Slack, Microsoft Teams, and Email, improving incident response and reducing mean time to detection (MTTD).
- ▹Designed dashboards for real-time observability, enabling faster troubleshooting and improved service reliability.

How AWS IAM Permission Evaluation Really Works
AWS doesn't randomly block you. It runs your request through a security gauntlet — and you need to pass every single checkpoint: SCP → Permission Boundary → Explicit Deny → Allow → Implicit Deny.
