Hire a Docker engineer who writes Dockerfiles like code
Multi-stage, small, scanned, cached. Not copy-pasted from Stack Overflow. Fixed monthly price.
Who this is for
Engineering manager whose team builds Dockerfiles by copy-paste from Stack Overflow.
The pain today
- Images are 2GB because the Dockerfile copies everything.
- Layers are cache-hostile; every change triggers a full rebuild.
- Security scanning is never run — every image has 200 CVEs.
- Registry is a free-tier plan with no retention policy.
The outcome you get
- Multi-stage Dockerfiles with images under 300MB for most apps.
- Layer caching discipline — source changes rebuild in under 30 seconds.
- Security scanning in CI, blocking critical CVEs.
- Registry strategy with appropriate retention and promotion rules.
What 'senior Docker' actually means
Senior Docker engineering is not exotic. It is: reading the Dockerfile best-practices doc and actually applying it, knowing which base image to pick for which runtime (distroless, alpine, slim), ordering layers so the cache works in CI, using BuildKit cache mounts for language package managers, writing multi-stage builds so the final image does not contain build tools, and running security scanners as part of CI so the team cannot ignore them. Every item on that list is documented. The senior engineer reads the doc. The junior engineer does not know the doc exists.
GigEasy + Imohub references
GigEasy runs Docker across Laravel plus React plus Postgres plus Redis in a 3-week fintech MVP. Imohub runs Docker across Next.js plus Laravel plus MongoDB plus Meilisearch as a real estate portal indexing 120k+ properties. Both use multi-stage Dockerfiles with image sizes under 400MB, ECR for the registry, security scanning in CI, and ordered-layer cache discipline. Same Docker patterns both times — different applications on top.
Security scanning — the part nobody does
Trivy or Grype run in CI, fail the build on critical CVEs, and warn on high-severity. Snyk for deeper dependency scanning when the team values it. Docker Hub vulnerability scanning for the registry-side view. Most teams do none of this, which is how a Log4Shell-level problem ends up shipping for six months after patches are available. Senior Docker engineering makes scanning mandatory — not optional.
Pricing and engagement
$3,499 per month flat. Dockerfiles authored and reviewed as part of the broader application subscription. For Dockerize-only projects (no ongoing work), scope and cost are set up front — typically 2 to 4 weeks for a mid-size app.
Recent proof
A comparable engagement, delivered and documented.
Rebuilt a real estate portal at a fraction of the cost
Rebuilt Imóveis SC's real estate portal as ImoHub — a faster, more scalable successor — handling 120k+ properties with sub-second search and drastically reduced AWS costs.
Frequently asked questions
The questions prospects ask before they book.
- Can you reduce image size without breaking the app?
- Yes. Multi-stage builds plus distroless or alpine plus dependency pruning. Typical reductions are 5 to 10x (2GB down to 200 to 400MB).
- Docker on Mac M-series silicon?
- Yes. Multi-arch builds (buildx) so images run natively on both amd64 and arm64. Important for dev-to-prod parity when devs are on M-series and prod is on amd64 EC2 (or vice versa).
- Docker Compose for production?
- Only for very small single-host deploys. For anything that needs multi-host, zero-downtime deploys, or autoscaling, use ECS, Kubernetes, or Fly.io — not Compose.
- Dev containers (VS Code devcontainer)?
- Yes when the team wants reproducible dev environments. Extra overhead for small teams; pays off on teams with 5+ engineers or complex dev setups.
- Do you handle docker-in-docker for CI?
- Yes. GitHub Actions with buildx works well. Docker-in-docker is avoided — rootless buildkit is the preferred pattern.
