Learn to do the job. Not just pass a test about it.
36 role-based courses that end in a live simulation week, a portfolio of real artifacts, and a completion credential you can actually share.
Checkout total is wrong when a discount code is applied
"A customer applied SAVE10 and the total didn't drop. We ship tomorrow - can you confirm and pin down exactly when it happens?"
Your task
Reproduce it, isolate the condition, file a bug a developer can fix without asking you a single question.

Names shown only to say what these courses hand off toward. CertClue is independent and claims no endorsement.
Pick a role, not a subject.
Every course targets a specific job you can be hired into, across 16 categories.
Seven parts. Fundamentals to handoff.
Every course follows this exact structure, so once you know one you know how to move through all 36.
Fundamentals, kept short
Just enough theory to function. Not the course.
The role decoded
Three real job posts, decoded line by line into what you would actually do.
A day in the role
Hour by hour, laptop open to sign-off, in the voice of someone who actually does this job.
The recurring calendar
The daily, weekly, monthly and quarterly rhythm nobody puts in a job description.
A live simulation
A worked week: requests arrive, priorities collide, something breaks. Judgement, not just execution.
Your artifacts
Every simulation produces something real: a portfolio piece and an answer to “tell me about a time when.”
The handoff
Interview prep built from your own artifacts, then the route to a matching certification if there is one.
All 36 courses, one shape.

Proof, not just a completion badge.
Anyone can hand out a certificate for watching videos. Every simulation produces something real that you keep and can put in front of a hiring manager.
- Real work samples from a simulated week, not quizzes
- A story for every “tell me about a time when” question
- A verifiable certificate of completion, honestly framed
What you keep, and what the certificate means.
- A real portfolio. Five artifacts per course, produced from the live simulation, not invented for a resume.
- A verifiable credential. A public link anyone can open to confirm your completion is genuine, not just a claim on a resume.
- Interview prep from your own work. The handoff module builds your answers directly from the artifacts you actually made.
Portfolio artifacts are self attested: submitting one confirms you did the work, not that it was independently graded. The certificate says exactly that.
It certifies completion of a CertClue course. It is not the industry certification, and it is not an offer of employment. To hold a vendor credential you sit that vendor's own exam. CertClue is independent and not affiliated with any certification body.
Built for your first, or next, tech job
We do not post reviews from people who do not exist. Here is honestly who this is built for.
I need proof I can do the job, not just another certificate.
Learn a role from zero and finish with real work samples. No degree required.
I have the theory but nothing to put on my resume yet.
Turn a simulated week of real work into a portfolio and interview stories.
I want to move up without paying for a bootcamp.

Questions people actually ask
No, and you can use either or both. Certification prep gets you ready to pass a specific vendor exam. Courses teach you to actually do a role day to day and leave you with a portfolio, then hand you off to the matching certification if one exists.
A completion certificate naming the course, plus a public, shareable verification link anyone can use to confirm it is genuine - built to add to LinkedIn or send with an application. It confirms you completed every lesson, passed every knowledge check, and submitted every portfolio artifact.
No. Submitting an artifact is self attested: you are confirming you did the work, and the certificate and verify page say exactly that rather than claiming anything was independently graded. Human review may come later; it is not part of the product today, and we are not going to imply otherwise.
No, and we would not claim that if it helped conversion, because it would not be true. What a course gives you is the judgement a hiring manager is actually screening for and a portfolio to prove you have it, which is a real advantage over a candidate with neither.
Yes, the same as every other part of CertClue.
