    Talent: Math "Top 0.1%". I rapidly understand situations and can't stop to incubate new Ideas and concepts. Thus i could turn out a key in moving your idea into a profitable beta and making it a failproof one backed by stochastics and statistics. And would like to leverage my skills by designing new robust social systems and programming core pieces, algorithms, distributed systems/databases, machine learning/AI, science. -- I look for milestone/performance-based payments, which fits unique non-repetitive work is most efficient for clients. I may also be happy to support your novel and positive or charitable project for free voluntarily. -- Yet i may very well turn out helpful in automating repetitive tasks which you would otherwise get done only manually through countless of freelancer hours. Through rapid prototyping the threshold of complexity/volume to break-even automation of a job is usually much smaller than clients expect and often comes with 100% accuracy.
