My name is Peter and I will be sharing my preparation to become (or not) Elastic Certified Engineer. I'm a little bit experienced already and trying to share my knowledge on my blog (in Polish) and help others on Stack Overflow. But not so experienced to go to the exam at once. Here, in this GitBook, I am planning to keep notes around my preparation based on the objectives. No matter if I will take the exam or not I hope to learn something new and share the notes with you.
