→AWS infrastructure: EC2 instances (eu-north-1), S3 buckets, IAM roles, SSM-based remote access (no SSH), security group allowlists across 8 global offices
→Container orchestration: Docker Compose fleet of 20+ services with sequential startup chains, health monitoring, auto-rollback, and OOM prevention on memory-constrained instances
→CI/CD pipeline: GitHub Actions workflows (centralized deploy-app.yml), S3 artifact rotation, per-service smart change detection, post-deploy health checks
→Reverse proxy & SSO: nginx routing, Cloudflare SSL termination, OAuth2 Proxy backed by Azure AD for single sign-on across all internal apps
→Credential & secrets management: OAuth token lifecycle (token-proxy auto-refresh), GitHub org secrets, PAT rotation, SSM Parameter Store, per-app .env files
→Data pipeline operations: EC2 #3 (Fabric → Parquet → S3), daily cron jobs, MSAL token refresh, lockfile and resume logic

→Security posture: network-level access controls, credential hygiene, OPSEC between corporate and personal identities

3–6 years hands-on AWS experience (EC2, S3, IAM, SSM — not just console clicks)
Solid Docker and Docker Compose skills; you debug failed container starts at 2 am without fear
GitHub Actions: writing and maintaining multi-job workflows with secrets, artifacts, and matrix builds
Linux system administration (Ubuntu): cron, systemd, disk management, process investigation
Python scripting for ops tasks (deployment scripts, health checks, API automation)
nginx configuration: upstream proxying, path-based routing, SSL
A security-first mindset: you default to least-privilege and always ask “what happens if this leaks?”
