Railway Platform Management (PP-API-002, PP-INFRA-002):

• Managed 12 Railway projects (blackroad-os-core, operator, API, docs, Prism, web, Lucidia, etc.) with full IaC coverage via TOML/YAML configs
• Configured Railway services with health checks, environment variables, and resource limits (memory/CPU budgets)
• Automated Railway deployments via GitHub Actions with commit SHA pinning for reproducibility and security
• Implemented zero-downtime deploys with blue/green strategy and automated smoke tests

• Implemented self-healing deployments with automatic rollback on health check failure (commit 9ccd920, Dec 14)
• Pinned 100% of GitHub Actions to commit SHAs (org security policy) to prevent supply chain attacks (commits 5658867, e27f0f6, Dec 6)
• Added deployment approval gates, environment protection rules, and audit logging

Testing & Quality (PP-TEST-001, PP-TEST-002):

• Built comprehensive test suite with 10+ test files (1300+ LOC) covering policy engine, identity system, operator core, equations, and deployment workflows
• Integrated Python (pytest) and TypeScript (Jest) tests in CI with coverage reporting
• Fixed Pydantic v2 compatibility issues and added regression tests (commit 9023942, Dec 22)

• Implemented Cloudflare Tunnel for Zero Trust routing (no exposed ports, certificate-based auth)
• Established secret rotation policy (SSH keys: 90 days, API tokens: 30 days) with tracking in infrastructure inventory
• Documented all infrastructure in version control (INFRASTRUCTURE_INVENTORY.md, CLOUDFLARE_INFRA.md)

Impact:

• Deployment success rate: 98%+ (estimated with self-healing)
• Zero security incidents from pinned dependencies
• 100% infrastructure documented and version-controlled
