I'm well-equipped to perform data analysis and derive actionable insights that you didn't know were there. API Integration: I'm also ready to download or upload data from APIs, implement API integration, or maintain state in a remote system via an API. Even the really hard-to-work-with ones. Not much slows me down. Data Engineering: Working from an SQL database, JSON file, XML file or spreadsheet, I can load the data, clean it up or transform it, and output it in any of the same formats.

I am a professor of economics at Seattle University (previously California State University Fullerton) with a PhD in economics from the University of Washington. I specialize in microeconomics and quantitative analysis, especially using observational data (although I have my share of experiment design experience as well). I have more than ten years of experience using Stata, and can help you with any Stata coding issues you have, or can help you learn Stata yourself. I am also an expert in R and have authored several moderately popular packages on CRAN. I can help with coding in some other packages or languages, such as Python, but I have less experience with those. I can help with research design, analysis, and data cleaning/preparation, either for projects that use observational administrative or government data, or for experimental design. Finally, I do plenty of work helping people edit or revise their research writing. As of this writing, I have thirteen published papers in applied economics and econometrics, and many more in the pipeline. I have extensive experience as a mentor and tutor helping people with their own class projects, theses, dissertations, or nonacademic research projects. I have many years of teaching and tutoring experience. I am a full-time professor, and am looking for supplementary work in order to save up for some major purchases. What I don't do: Please note that I am an economist, not a financier or businessperson. I am unlikely to be able to help you design investment plans, business operations, or a blockchain white paper. I'm also not a specialist in time series analysis. If you've already figured out how you want your time series model run and you just want someone to code it up, I can help with that. But if you want someone to help design your time series model you may be better off with a time series expert. Finally, I do most of my contract work late at night. While I can certainly meet via phone or videocall once or twice to get a project set up, if your job requires a lot of meetings, I'm probably not the right person for you. Hourly rate can be negotiated depending on the project, but I am unlikely to accept a significant cut.Data CleaningREconomicsQuantitative AnalysisEditing & ProofreadingStataData AnalysisEconometricsData ScienceCausal Inference - $80 hourly
