Languages & Testing: Python Java React pytest GitHub Actions CI/CD

🚀 Featured Projects

Project Stack What it does
SmartScan Node ESP32, AWS IoT Core, Lambda, DynamoDB, Terraform Elder care occupancy monitoring — ESP32 publishes sensor telemetry via MQTT over TLS to AWS IoT Core, Lambda writes to DynamoDB, SNS fires alerts. Semi-finalist, Northeastern Husky Pitch Summit 2025
AWS Scalable Web Infrastructure Terraform, VPC, ALB, ASG, RDS, CloudWatch Production-grade AWS infra — ALB across 3 AZs, Auto Scaling driven by CloudWatch CPU alarms, RDS MySQL in private subnets. Load-tested to verify scale-up at 75.6% CPU
Fintech Fraud Detection Python, FastAPI, Docker, Kubernetes, KVM/QEMU FINTRAC-themed fraud detection API on a self-hosted 3-node Kubernetes cluster — auto-scales 1→5 pods under load, self-healing, rolling updates
