Professional Experience

Senior Infrastructure Engineer June 2021 – Present
Square San Francisco, CA
  • Architected a standardized Docker-based development workflow for 120+ engineers, reducing 'it works on my machine' support tickets by 65% in the first quarter.
  • Optimized production Dockerfiles using multi-stage builds and Alpine-based images, shrinking the average image size from 1.4GB to 165MB and speeding up cold-start deployments by 4x.
  • Engineered a custom CI/CD pipeline using Docker-in-Docker (DinD) and GitHub Actions, cutting build-to-deploy latency from 22 minutes to under 7 minutes for Square's core payment services.
Software Engineer (Platform) August 2018 – May 2021
Databricks San Francisco, CA
  • Containerized legacy Python data processing workloads for migration to Databricks-managed Kubernetes clusters, improving cluster resource utilization by 35%.
  • Automated the provisioning of ephemeral Docker staging environments for every pull request, allowing QA teams to validate features in isolation and reducing merge conflicts by 40%.

Projects

Kube-Janitor Open Source Contributor Go, Docker, Kubernetes API
  • Developed a cleanup utility that identifies and removes orphaned Docker volumes and stale container images in dev clusters, saving approximately $2k/month in EBS storage costs.

Write Docker Bullets That Prove Seniority

Effective resumes move past 'I used Docker' and focus on how containerization improved the development lifecycle and system reliability.

❌ Vague/Generic

Used Docker to containerize applications for the team.

✓ Impact-Focused

Containerized 12+ microservices using Docker, enabling consistent environment parity across dev, staging, and production, which reduced deployment-related bugs by 50%.

Copied!

Why it works: It defines the scale (12+ services) and the specific business outcome (50% reduction in bugs).

❌ Task-Focused

Maintained Dockerfiles and managed images on AWS ECR.

✓ Results-Driven

Refactored Dockerfiles to utilize build caching and multi-stage builds, reducing CI pipeline execution time by 12 minutes per run.

Copied!

Why it works: This shows a deep understanding of Docker internals (caching/multi-stage) and quantifies the time saved for the engineering org.

❌ No Metrics

Improved local development setup using Docker Compose.

✓ Quantified Achievement

Replaced manual setup scripts with a Docker Compose environment, reducing new engineer onboarding time from 2 days to 15 minutes.

Copied!

Why it works: Onboarding time is a metric every manager cares about. It turns a tool-specific task into a team productivity win.

❌ Passive Voice

Security vulnerabilities were reduced by scanning Docker images.

✓ Action-Oriented

Integrated Snyk into the Docker build process to automatically block images with 'High' or 'Critical' vulnerabilities, securing the supply chain for 40+ production apps.

Copied!

Why it works: It demonstrates proactive ownership and mentions specific tools (Snyk) and the scope of the impact (40+ apps).

Docker Resume Strategy FAQ

Direct answers on how to showcase containerization skills for backend and infrastructure roles.

Should I list Docker under my skills or within my job descriptions?

Do both. List it in the 'Skills' section for ATS searchability, but prove you actually know it by describing specific problems you solved with it in your 'Experience' section. A hiring manager needs to see the context of how you applied the tool.

What Docker-specific keywords do hiring managers look for?

Beyond just 'Docker,' look for related concepts like multi-stage builds, container orchestration (Kubernetes), image optimization, Docker Compose, and CI/CD integration. These terms signal that you understand the ecosystem, not just the basic commands.

How do I show Docker experience if I only used it for a small side project?

Focus on the 'why.' Describe how Docker helped you manage dependencies or how you deployed that project to a cloud provider using containers. Even for side projects, mentioning that you containerized the app for portability shows professional intent.

Is it worth mentioning Docker if the role is for a pure Backend Developer?

Absolutely. Modern backend engineering is inseparable from how code is shipped. Knowing how to debug a container or optimize a build makes you a much more self-sufficient and valuable engineer than someone who just writes code and throws it over the wall.

What is a common mistake when putting Docker on a resume?

The biggest mistake is listing it alongside 20 other keywords without ever mentioning it in a bullet point. If it's a core skill, I expect to see at least one bullet point explaining how you used it to make a system faster, more reliable, or easier to develop.

How can I stand out if everyone else also has Docker on their resume?

Talk about the 'day two' operations. Anyone can write a Dockerfile. Show that you know how to handle security patching, image size optimization, or complex networking within Docker Compose. That level of detail separates seniors from juniors.
