Prove your DevOps skills
DevOps is judged by what happens when a deploy goes wrong. Lemma records how you build pipelines, roll back safely and find the cause of an incident, through code, sessions and assessments.
What DevOps competence looks like
A strong DevOps engineer makes shipping boring. Every change goes through an automated pipeline with tests, builds and checks that catch problems before production. Deploys are small and frequent, with a rollback or feature flag ready, so a bad release costs minutes rather than a weekend.
They also make systems visible. Logs, metrics and traces answer real questions, alerts fire on symptoms users feel, and runbooks exist before they are needed. After an incident, they run a blameless review and fix the system, not the person. Developers trust their tooling because it saves them time.

Practitioner · after the call
Clear reasoning on ci/cd pipelines. Talked through trade-offs first.
CI/CD pipelines
Automated build, test and deploy stages that run on every change and fail fast when something breaks.
Release strategies
Blue-green, canary and feature-flag releases that limit blast radius and make rollback routine.
Infrastructure as code
Reviewable, versioned definitions of environments so staging and production stay consistent.
Observability
Logs, metrics and traces wired together so you can explain what a system is doing and why.
Incident response
Triage, communication, mitigation and blameless reviews that turn outages into lasting fixes.
Secrets and configuration
Keeping credentials out of code and images, and managing configuration safely across environments.
What counts as evidence of DevOps skills?
Certificates in DevOps show an exam was passed. Lemma records how you work: sessions where you talked through a design or an incident, an adaptive test, and configuration in repositories you link. Every entry says where it came from. See the evidence methodology for how each source is weighed.

Pipeline and deploy configuration
Connect GitHub and attach a repository or commit with your CI workflows, deploy scripts or infrastructure code. Lemma confirms access and re-checks the link periodically.
A live incident walk-through
In a session, a practitioner describes a failing service and you investigate out loud: what you check first, how you mitigate, what you change afterwards. Your method is what gets rated.
Diagnosing a failing pipeline
The adaptive assessment shows realistic situations, such as a CI config that never deploys or a script that leaks a secret, and you pick the correct diagnosis or fix from the options.
Teaching release safety
Teaching a session on canary releases, rollbacks or alert design counts more than learning one. It shows you can spread good practice across a team.
How is a DevOps skills test run on Lemma?
The DevOps test is adaptive, 15 to 25 questions on failure modes, permissions and cost rather than service names, and it stops once your level holds steady. With sessions and linked work it sets your DevOps SCI, where recent evidence carries more weight.
A deploy broke checkout for every user at once. Which practice limits that next time?
- ADeploy only on Fridays
- BLonger code freezes
- CManual approval for every commit
- DCanary releases with automatic rollback
Link pipelines you built
Attach GitHub repositories or commits containing your CI/CD workflows and infrastructure code. They show real automation you designed, and Lemma keeps checking the links remain valid.
Handle an incident in a session
Book a live session with a DevOps practitioner and work through an incident or deploy scenario. They rate how you prioritise, mitigate and communicate, not just the final answer.
Take the adaptive DevOps assessment
Scenario-based multiple-choice questions cover CI/CD, releases, observability and incidents. Difficulty adjusts after each answer, harder questions count for more, and timed questions with no going back keep it fair.
