Freelanced as an econometrician and data scientist (my client was a banker and needed assistance with a project involving high dimensional economic and financial data) in addition to conducting interviews for Cambridge and Oxford University in Economics.

Income was let's say, enough. Not consistent though, partially because it's not easy to get clients(People don't apply to Oxbridge every month), and now I'm officially looking for more quant/statistical work - Get the sense that I won't be satisfied in a typical 9-5 though, so let's see what will happen.

Experience: A few internships in management consulting, human rights etc, many years of teaching and consulting.
Industry: Finance, education
Tenure: One month so far.
Qualifications: Economics BA, full scholarship.
