Praktikum Hero or My First Ever Hackathon

Praktikum Hero or My First Ever Hackathon

In the second half of November I participated in my first hackathon organized among Yandex.Praktikum’s graduates, it was the graduate community’s first one too, so I was happy to join cause I know the community well. We were 5 in a team which consisted of a backend, and a frontend developer, QA software tester, and two data scientists. I was one of the two latter ones (it’s a data blog after all). All of us didn’t know each other before we were teamed up.

Our task was to build a prototype of a functional real-time analytics platform to test hypotheses and see the results. We had 24 hours. We got data from a homeless pet care service where one can donate to various shelters based in multiple cities across Russia. So the datasets included transactions per pet with a description and each pet’s profile information.

Before the task description was announced, we got a tip from a jury member to spend the time with fun. So when we started our heated discussions with an attempt to create a great hypothesis, that was the advice that we eventually followed, our hypotheses were:

  1. To see if male cats are getting adopted less often than female cats cause they mark the territory (maybe?)
  2. Female cats get more donations for gifts like toys, while boys get more practical donations like medical insurance.

We also generated a few other ideas while being excited in our brainstorm session but they were not doable due to the lack of data as it was discovered in the process.


When my data part was done, I was thinking about how to contribute more cause it felt like the role of data people is quite limited to the first stages of the project development at least during the hackathon, so once we received a project name suggestion from a QA who called it Tomcats vs Pussycats (well, and Dogs) (a rough translation), I made a logo, then some illustrations and went to sleep with peace of mind at around the time other team members did in their according time zones.

I also understood the value of communication, as you may see in the video, there are bar charts but we discussed them as if they were supposed to be pie charts when I submitted my first contribution, that’s fine though, as one could change the thing quickly in an actual practice but that was too late when it had appeared like that before the judges, cause I believe this detail could affect them somehow, and so it was a lesson for me to stay updated and check those things until the end in the future.

My team’s prototype for the presentation

Overall, it was a great experience. I got to know new people. Everyone was quite easy-going. We had a lot of fun together and got rewarded by the organizers for that as well. We received certificates in .pdf, so I’m leaving mine here. 😄
