Services

A practical menu of common engagements. If it touches Linux production, it’s probably in scope.

Incident response

Rapid triage, containment, recovery, and postmortems. Stop the bleeding and prevent repeats.

  • Service restore + root cause analysis
  • Runbooks + alerts cleanup
  • Backup/restore validation

Linux hardening

Reduce risk with secure baselines and continuous patching you can actually maintain.

  • SSH + sudo policy, firewalling
  • Patch strategy and automation
  • Audit logs, least privilege, MFA

Hosting & migrations

Move workloads with minimal downtime and a clear rollback plan.

  • Cloud or bare-metal migrations
  • DNS + TLS, reverse proxies
  • Performance tuning

Observability

Monitoring that answers “what broke?”, “why?”, and “what changed?”

  • Metrics + logs + traces strategy
  • SLOs, alerting, on-call hygiene
  • Dashboards that match reality

Automation

Fewer manual steps, fewer mistakes. Repeatable infrastructure and releases.

  • CI/CD improvements
  • IaC: Terraform / Ansible
  • Golden images and bootstrap scripts

Cost & reliability

Right-size, remove waste, and harden failure modes.

  • Cloud spend review
  • Capacity + scaling plan
  • Resilience: backups, DR, HA

How it works

Simple, transparent, and focused on outcomes.

Quick intake

Share symptoms, access constraints, and success criteria. For emergencies, start with SMS.

Triage & plan

We prioritize safety and uptime, then choose the smallest set of changes that fixes the real issue.

Execute & document

Changes are tracked, reversible where possible, and documented so you’re not dependent on me later.

Emergency on-call

A clear “big red button” when production is down or security is urgent.

What qualifies as an emergency

  • Outage or major degradation
  • Active security event / suspected compromise
  • Data loss, restore needed
  • Production deploy rollback needed

What to include in the SMS

  • Your name + company
  • System/URL affected
  • What changed recently
  • Impact (users, revenue, severity)
  • Best call-back number (optional)
