I have been into programming for about 8 years. So I think I will be able to help with what all is required. I have been doing CP in C++ for quite some time which made me an Expert at Codeforces and 5* at Codechef. I also have experience when it comes to practicing on the platforms like Hackerrank, Hackerearth, Leetcode, GFG, etc. under the username "ujjwalsingh30". I had also participated in ACM-ICPC Regionals last year. We can discuss further details in chat.
