ABOUT ME
I just want to help you.
I just want to help you.

I really like solving problems. Especially connected with algorithms, which involves thinking. It gives me pleasure if I can help someone.
I did a lot to be very good at algorithms, competed in many algorithm competitions and now I am on the other side - I create problems for such competitions and try to share of everything I learned earlier (because of these competitions).

Most of my code I am writing in C++. Most of my professional work was done in C++ (including work at Google). On ACM ICPC World Finals and regional competitions earlier we used C++. Now when I am preparing competitions, creating problems, model solutions and input generators are almost always in C++.

Participated many times in regionals of ACM ICPC. Once on ACM ICPC World Finals. I am very actively working on creating problems for such competitions. Also I am working as teacher in school where I teach algorithms and data structures young, bright students (mostly High School). Some of them have successes in Informatics Olympiads on national level. Also, in professional job I used algorithms very extensively. For example when I worked in company creating computer games I helped them with ranking formula for matching players, so their level is similar.

I use Python as scripting tool. Whenever I want to write some small piece of code quickly and I know it will take me 10-50 lines - I do it in Python. At Google some of my code was written in Python. Especially when I helped in organising Google Code Jam competition. I don't think I am expert at Python, but I wrote a bit of code in Python and feel quite comfortable.

Karol is the absolute best when it comes to algorithms! He can solve any challenge the most efficient way, and no algorithm can prove difficult for him. I had the pleasure of working with him and I'm looking forward to it again in the future.

Karol was really great. He understood (what I thought) a difficult problem well in a short time and was able to explain it to me and make the solution so simple that I could understand myself. Awesome.

He is very honest, and clear lecturer(I would say lecturer, not a mere tutor). He do his best to enlighten me and he knows how to attack problems step by step logically. I am very disorganized when I am thinking of problem, but it is getting better from his coach.

Cant reccomend his help enough. Everything taught was created in the session from scratch. He didnt jump on stackoverflow and pull other peoples code or anything like that. Helped me getting my setting up my algorithm and took the time to explain any step i was confused with. Incredibly helpful, patient and respectful with regards to time and price. 100% 5*
