PROJECTS

Kubernetes Scalable Platform

•Designed and deployed a containerized backend application to a local Kubernetes cluster (kind), transitioning from a single-instance architecture to a scalable, self-healing deployment model.

•Engineered high availability through rolling updates, replica management, liveness/readiness probes, and PodDisruptionBudgets to support controlled, zero-downtime releases.

•Implemented Horizontal Pod Autoscaler (HPA) with 70% CPU utilization threshold to dynamically manage scaling under stress conditions.

•Simulated pod crashes and resource exhaustion scenarios, reducing mean recovery time (MTTR) to <30 seconds through proactive probe configuration and troubleshooted and diagnostic analysis using kubectl logs and events.

Log Detection and Response System

•Processed 2000+ simulated log events per minute through Kinesis Data Firehose into S3, enabling near–real-time ingestion and structured storage for analysis.

•Developed AWS Lambda detection logic that identified error patterns and suspicious activity, triggering Amazon SNS alerts within <3 seconds of anomaly detection under load testing.

•Applied Identity and Access Management (IAM) principles, including least-privilege role-based policies, to secure inter-service communication across S3, Kinesis Data Firehose, Lambda, and CloudWatch.
