What I've Built

Four production-grade automation tools built using Claude Code, grounded in real enterprise Linux infrastructure.

01 — FEATURED
📊

ELK Monitoring Stack
on AWS

Full-stack observability deployment on AWS: Logstash pipeline-to-pipeline routing, Elasticsearch with ILM index policies, Grafana dashboards, and Prometheus + cAdvisor for container metrics. Includes syslog centralization and alerting configuration.
