    Math. Crafting fast social/charity-startups. Rent my brain

    Germany - Last active: 15 days ago - Tests: 12

    Talent: Math. One in thousands. In love with desiging & modelling any concept, (social-) system, startup and their pratical implementation/process, mission, credo, by-law, patent to surpass financial projections as well as interlectual/moral goals! I rapidly understand situations and seemlessly solutions flash up & incubate until failproof/backed by stochastics and statistics. 2. I'm looking to cofound or volunteer for any social projects. I managed charity campaigns successfully. 3. I hope to leverage my skills by coming up with algorithms and core code for any science project, boinc, distributed systems/databases, machine learning/AI, dao. I dont believe in hourly payment for unique/non-repetitive work. Rather milestones (, shares or votes) 4. I'll easily be profitable in automating any relevant but repetitive tasks and saving human working hours. Tasks / Processes usually turn out much smaller than clients expect - after all you can devide any complexity by volume. 5.
