Pick small projects that each prove one delivery skill: a pull-request quality gate, a configuration validation exercise, and a release with rollback. Each should run on your laptop or a free environment, include a failure you cause on purpose, and finish with a written note on what the checks cannot catch.
Choose one small application and a disposable environment. These independent briefs demonstrate delivery reasoning without requiring a large cluster or access to production systems.
How do I choose a project?
Choose by your current gap, not by what sounds impressive.
- New to Git and pipelines: start with project 1. It teaches you to trigger checks from a change.
- Comfortable with a language but weak on containers: do project 2. It forces you to think about settings and clean startup.
- Already have a pipeline: do project 3, because release and recovery is where most real incidents are handled.
You do not need all three. One finished, well-explained project is more useful than three half-built ones.
How do I work through any of them?
1. Write the goal in one sentence and the evidence that would prove it. 2. Build the smallest working version and commit it. 3. Add the failure case and show that your checks catch it. 4. Write the README as if a stranger will reproduce it. 5. Clean up the resources you created.
1. Pull-request quality gate
Create a small application with a meaningful test and formatting or type checks appropriate to its stack. Configure checks for proposed changes.
Deliberately introduce a failing case and verify that the release step cannot proceed. Deliver the repository, workflow file and pass/fail evidence. Check that the workflow uses the intended source revision and does not expose secrets.
Explain which bugs the checks can detect and which behaviours remain untested.
2. Configuration validation exercise
Build an application that requires a small set of runtime settings. Provide a safe example configuration and clear validation for missing or malformed values.
Package the app in a container and test clean startup, a missing field and an invalid port or URL. Deliver the setup guide, validation output and container definition.
Keep real credentials outside the image and repository. Discuss why configuration errors should be clear without revealing sensitive values.
3. Release observation and rollback
Prepare two tagged versions of a sample service. Define a health check and release to an authorised staging or local environment. Introduce a controlled failure, observe it and restore the known working version.
Deliver a release checklist, incident timeline and recovery runbook. Check that the restored version is actually serving requests and consider whether data changes would affect recovery.
Remove test resources and inspect any continuing cloud charges. Explain why successful rollback in this simple exercise is not proof that every production rollback is safe.
Portfolio packaging
Include prerequisites, exact reproduction steps, expected results and limitations. Use screenshots as evidence alongside the underlying configuration.
A strong explanation focuses on the decision behind each check and the recovery path after failure. Avoid adding tools that do not serve the project's purpose; a small coherent system is easier to review and more useful to learn from.
How do I check a project is finished?
Ask a friend, or a mentor, to clone your repository and follow the README without your help. Note every place they get stuck and fix the document. Then ask yourself three questions: what failure did my checks catch, which failure would they miss, and how do I return to a working state? If any answer is vague, the project is not finished.
What should the README contain?
Write it so a stranger can reproduce your work.
- A one-sentence goal and the evidence that proves it.
- Prerequisites and exact setup steps.
- How to trigger the failure case and what you should see.
- How to recover, with the expected result.
- Known limitations and how to clean up resources.
If the README is clear, the project explains itself in a review or a conversation with a mentor.
What are the common mistakes?
- Adding tools to look advanced, such as a cluster for a one-page app.
- Showing only the successful run. Reviewers learn more from the failed run and the recovery.
- Leaving cloud resources running after the exercise.
- Committing real credentials into the sample configuration.
What should I build next?
