- Production hardening on Windows Server + cloud edge: NGINX/Traefik reverse proxy, wildcard TLS/SSL, DNS/NAT, Azure Front Door/CloudFront CDN; CSP/HSTS/Helmet/CORS, health/readiness probes, diagnostics endpoints → incidents ↓ ~35%.
- DevOps & reliability: GitHub Actions CI/CD (build/test/security scans, Docker), blue-green deploys, cron/Azure Functions/Lambda jobs, Terraform (IaC), structured logging, Prometheus/Grafana + Sentry → 99.9% uptime, MTTR ↓ ~38%, change failure rate <5%.
- Cross-functional delivery: converted ambiguous asks into PRDs/runbooks/SLAs; 2-week cadence, measurable ops wins (time-to-value ↓ ~50%, internal NPS +18), clear ownership and stakeholder sign-off.
