I’m an entry-level DevOps and Site Reliability Engineer who enjoys building production-ready infrastructure with a strong focus on security and automation. I bring backend development context (Python/Flask, Node.js, REST APIs) to understand the full delivery lifecycle—from development to deployment to monitoring.

In my HNG Internship (DevSecOps Track), I delivered real infrastructure work evaluated by senior engineers. I provisioned AWS EC2 servers, configured Nginx reverse proxy with SSL/TLS via Certbot, applied SSH hardening, and containerised a three-service microservices application with Docker and a 6-stage GitHub Actions CI/CD pipeline.

I also built security-focused detection and response systems, including a Python-based Anomaly Detection and Intrusion Detection System using z-score log analysis. It automated iptables IP blocking, sent Slack alerts, and ran on AWS EC2 with a live dashboard deployed through a multi-stage GitHub Actions pipeline.

On the platform side, I architected a GitOps Kubernetes platform on AWS EC2 using k3s, ArgoCD, Helm, and Argo Rollouts. I implemented canary deployments with automated rollback triggered within 2 minutes of failure detection, and I integrated Prometheus and Grafana for real-time cluster observability—backed by my production monitoring/observability stack work with Alertmanager routing and threshold baselines.
