i need an expert coder in python to build an financial analysis and test its robustness

I would like to perform an analysis on python that supports my research. The analysis involves the creation of portfolios based on its ESG performance. the portfolios are composed of equities within the same ESG rank. these portfolios have to be optimised (markowitz) to then output an optimised max sharpe ratio portfolio, i have ranked 1-10 for each possible ESG component therefore having 70 portfolios + 1 for no-ESG data. on the econometrics side the model has to be tested thoroughly for its robustness.
