  • ▹Built an Ansible automation platform running in containerized Execution Environments (ansible-builder/ansible-navigator) with a custom-built AWX deployment, Vault-encrypted secrets, and playbooks for server bootstrap, GitHub provisioning, Elastic Agent rollout, and patch governance.
  • ▹Deployed and maintain a custom Dockerized Apache Superset analytics platform with Hive Metastore/Trino integration, Celery background workers, and an MCP server enabling AI assistant access to dashboards.

DevOps Intern • Jun 2025 - Jan 2026

  • ▹Built "run", a schema-driven CLI (Ink/Pastel/TypeScript) for provisioning and maintaining Ubuntu dev servers with dependency-aware package installs, dry-run planning, and self-update, adopted fleet-wide via Ansible.
  • ▹Built the monitoring stack for a Temporal + PostgreSQL deployment: Prometheus scraping PostgreSQL exporter metrics remotely from a separate replica host, visualized in Grafana with alerting.
