Infrastructure that lets your team ship without hesitation.

Most teams reach out after a failed deploy, a climbing AWS bill, or when the person who built the infra has left. That is exactly the point I step in.

The real problems, named plainly.

Clients hire me when the bill is too high, the migration is overdue, the “server guy” vanished, or deployments are still manual. Here is how I address each one.

Cost Audit01
> auditing idle_resources... found 6

Cut your cloud bill

Most accounts I audit are bleeding 20–40% on compute they never needed. Idle EC2 instances running 24/7 for a site that gets traffic for 3 hours a day. Unattached EBS volumes accumulating charges. Load balancers pointing at nothing.

  • Rightsize oversized EC2 / RDS instances
  • Terminate zombie resources (EBS, EIP, idle LBs)
  • Reserved Instance / Savings Plan strategy
  • Autoscaling so you pay for load, not headroom
  • S3 lifecycle rules for cold storage
  • Cost anomaly alerts before the bill surprises you
Migration02
> planning cutover... rollback_plan: ready

Cloud migration

Migrations fail when the rollback plan is an afterthought. I treat it as a first-class deliverable — defined before the first resource is provisioned. That is how you move off cPanel, an over-provisioned VPS, or a reseller host without a Sunday-night outage.

  • Lift-and-shift vs. re-architecture decision
  • Zero/minimal-downtime cutover plan
  • Rollback procedure documented before go-live
  • DNS cut and SSL transition without downtime
  • Right-sized target infra — no over-provisioning
  • Post-migration cost and performance baseline

Replace your “server guy”

When infrastructure lives in one person’s head, you have a single point of failure that is not on any architecture diagram. I deliver IaC (Terraform / Ansible), runbooks, and Prometheus + Grafana alerting — so you catch issues before your users do and are never dependent on one person’s availability.

  • Terraform state for all infra — nothing manual
  • Ansible playbooks for repeatable server config
  • Prometheus + Grafana alerting before downtime
  • On-call runbook with escalation paths
  • Clean handover — zero knowledge locked away
  • Response SLA on active projects: under 24 h

> deploy_mode: ssh_by_hand... replacing with pipeline

Stop deploying by hand

Manual SSH deploys mean every release is a manual QA step and a potential typo away from a broken production environment. Automated CI/CD pipelines make deploys boring: push to main, tests run, staging gates pass, production updates — no one is up at midnight watching logs.

  • GitHub Actions / GitLab CI pipeline from scratch
  • Docker build + registry push automation
  • Staging environment gate before prod deploy
  • One-command rollback on failed release
  • Secrets management via Vault or AWS SSM
  • Deploy time cut from 40+ min manual to under 5
