I help teams launch and operate reliable web applications on Linux, Docker and cloud infrastructure. Work can include a production-readiness audit, Linux hardening, Nginx, AWS, DNS and TLS, PostgreSQL or MySQL, CI and CD pipelines, health checks, rollback, automated backups with restore testing, and monitoring and alerting. I review existing tools before recommending changes. Security is part of the SDLC from day one: least-privilege access, protected secrets, and approved production changes with backups and rollback. Each engagement starts with a defined milestone and time budget. Deliverables include a prioritized risk register or implementation plan, documented changes, verification evidence and a practical runbook. Support hours and escalation expectations are agreed separately. Feature development, hosting and third-party fees, major rebuilds and 24-hour on-call coverage are excluded unless explicitly scoped. Share your stack, hosting provider and main goal to discuss a starting point.
