Dmitriy Vasilets

I studied with Dmitry for about 2-3 months quite actively. Then there were several episodic subscriptions. I planned the training for the month of January, after taking a vacation (the whole of January was free) and planned to go through a significant part (later I realized that this assessment was rough). I had no scala experience, big data stack, and no java either. The big data courses attracted me by the fact that the description said that some contribution to the open source application Spark by the student himself would be made. About the training itself. (At the time of launch, he worked as a devops, before that he had some development experience in ruby.) The training was quite difficult, there were many mistakes in various places, somewhere there was a lack of admin knowledge (unix), somewhere in development, the lack of knowledge of jvm affected platforms. During the training, a summary was made in English. It seems a trifle, and then I sent it so many times to all kinds of companies, very well when it is ready in advance. It was also possible to take part in the development of a tool for correcting dates in the scala documentation, in the official repository, and it was a very cool experience, since the knowledge of scala was slightly more than zero. Correspondence, etc. - everything had to be done in English. We also had to configure openvpn (route, iptables, tcpdump, etc.), install kvm virtualization on a clean server for deploying the master and agent nodes of Ambari. But this is my additional wish, this is not in the mandatory program. The main difficulty for me was that I could not read the source code of some hadoop or spark, approximately I understood what was happening, but it was only about. Dmitry always gave a lot of different sources to various questions (only time needs to be found to see everything), promptly answered and explained. After the courses there were several interviews with European companies. It was also decided to additionally engage in written English, since the correspondence was difficult for pull requests and with employers. Following the results, I passed a technical interview in EPAM with relocation to Prague at the engineer’s devops, but later they had some kind of a hitch and I already got a job elsewhere in my city. Now I’m a Big Data developer, currently a java project. The stack used is hive, java, scala / spark, pig, someone else has to poke around with oracle / psql. Based on the results, I can say the following: investing money in my training is one of the best investments I have made over the past few years and I am very grateful to mkdev, Dmitry and Cyril (I also studied from him) for the knowledge that I received here. I saw programming courses very different and mkdev were not the very first for me, so I have something to compare with. And there was a time when I tried to do something by books, etc., now I know that the effectiveness of this “self-reading” is rather low (but there is, of course, anyway). Now I plan to get confident form in java and scala and it is quite possible that I will return here again to pump my skill. Thank you very much! =) Hooray hooray hooray! =)

Strict, demanding mentor. It helps to understand absolutely all the questions that arise, regardless of whether they relate to the course material or not. You don’t learn from him a set of tools (with beautiful logos that you can stick on your MacBook), you learn from him to be an engineer - learn to understand how technologies work, learn to combine them, learn to find effective solutions for various tasks. Getting into students is great luck if you want to study. With his help, got a job in an interesting Berlin startup.
