Free Kotlin Certificate
Finish the SnipDojo Kotlin curriculum and get a certificate of completion — free, with no subscription and no exam fee.
The certificate is earned, not bought. You work through all 12 lessons and 72 steps of the curriculum — about 3 hr 36 min of reading and practice covering variables and types, control flow, loops, functions, classes, collections, null safety, and lambdas. Every practice step is checked by a real test harness that runs your Kotlin in the browser, so you cannot skip ahead by guessing: the code has to actually produce the right output.
Once the last lesson is complete you can request your certificate. Each request goes through a short review, and once it is approved your certificate is issued in your name with a unique certificate ID. You can download it as a PDF and share it on LinkedIn, in a CV, or with an employer.
Every certificate carries a QR code and a public verification link, so anyone you send it to can confirm it is genuine without taking your word for it — the link resolves to a SnipDojo page showing the holder's name, the course, and the issue date.
