Hello
As a former competetive programmer I am very profficient with C++. I'm in the industry for several years, but I'm new on this site hence I do not have any ratings to show you. As a result of that I'm offering you a very low price.
To be honest, I would have done that for free in exchange for a good review on my profile. I can assure you that if you work with me once, you will always work with me for these kind of projects.
[I'm looking forward to working with you.
