    *** Please note, I get a fair number of invitations to interview for jobs where the budget is very low, $50 or $25 and so on. While I would like to help, I just don't have the time for smaller or low-budget projects. I am looking for larger, multi-hour projects that are paid on an hourly basis (not flat fee) and have a minimum budget of $500. Thanks for understanding. *** I have over 30 years of experience in research, evaluation, statistics, and project management. I have advanced evaluation and statistical analytic skills and am fluent in Stata and SPSS and have been developing my analytic skills using R to where I am now comfortable working in this language as well.. I also use Mplus for latent variable modeling. I have designed and analyzed online surveys using Survey Monkey, Qualtrix, and REDCap. I have a PhD in clinical psychology and am a tenured Full Professor. I teach beginning and intermediate statistics to doctoral and master's level students. I also teach program evaluation and mental health policy, including substance abuse policy. For samples of my writing style, you are welcome to use the "Look Inside" feature on Amazon to review sections of my book: Substance abuse in America: A documentary and reference guide. I am also happy to provide samples of papers published in peer-reviewed journals. My writing and oral skills are excellent and I am comfortable both developing as well as conducting trainings, workshops, and presentations. I can also help with editing and writing technical or non-technical documents but I am highly selective about this kind of work. I will be happy to review sections in dissertations and theses, but I will not write these or other student papers because I believe this violates academic integrity. I also will not accept homework assignments for the same reason. Things I can help you do: 1) Translate data in Excel or ASCII format into a data set for analysis in just about any commonly used statistical program. 2) Run basic screening and descriptive statistics such as frequencies, measures of central tendency and dispersion, and distributional statistics to assess skew and kurtosis. 3) Run bivariate analyses such as t-tests, correlations, and chi-square tests as well as non-parametric procedures like Kruskal-Wallis. 4) Check missing values and conduct imputation-based analyses for missing data as needed. 5) Run more advanced analytical models including: factorial ANOVA, regression (OLS, binary, ordinal, and multinomial logistic as well as Poisson and negative binomial), GEE for repeated measures data, HLM, factor analysis, latent class analysis, SEM, and growth mixture models. 6) Review and advise on statistical analyses already run including interpretation of the findings. 7) Review, advise, and edit write-ups of statistical results and methods sections. 8) Prospective advice on study design, including sampling, measures, and data collection protocols. 9) Write and edit proposals. I am available to be a project evaluator and would be happy to help you write the evaluation section of your proposal as well as conduct the evaluation if funded. Or, if you just need a review and editing of your proposal, I can do that as well. 10) Develop surveys and survey questions. I have extensive experience developing surveys including online surveys using tools such as Survey Monkey, REDCap, and Qualtrics. If you are unsure whether I can help with your project, please do not hesitate to send me a message. I reply promptly and will give you an honest answer. I never take on work that I don't feel I can complete successfully and within your time frame or which might take me an inordinate amount of time.

    Services: - Development of algorithmic trading systems for a wide range of assets including equities, futures, options, crypto and forex - Automation, backtesting and quantitative research - Evaluation, optimization and consulting to improve investment strategies such as avoiding backtest overfitting and other common pitfalls - Creation of customized indicators, factors, signal services and market scanners including automated notifications - Development and enhancement of framework modules such as execution algorithms (including TCA) and portfolio optimization models - Increasing the efficiency of trading algorithms so that large amounts of streaming data can be processed faster and less hardware resources are required Technologies & Tools: - Python including a wide range of libraries like pandas, numpy, numba, scikit-learn, matplotlib, seaborn and many more - QuantConnect / LEAN - Git and GitHub for version control and collaboration - Supported brokers for live and paper trading: Interactive Brokers (IB), Tradier, Binance etc. Bio: Quantitative trader and mathematician with strong affinity to financial markets and coding. Extensive experience in design, development and analysis of algorithmic trading strategies. I have been trading various financial instruments (equities, futures, options and currencies) for more than 10 years, whereas my approach has become more and more systematic over the years. I graduated with a Master's degree in Mathematics at University of Technology Dortmund (Germany) in 2016. My master thesis is about Schroedinger asymptotic of wave equations in periodic media. The subject belongs to the field of nonlinear partial differential equations and has applications in signal transmission using fiber optics technology. I then worked as an IT Consultant for 3+ years and was mainly employed as a data warehouse engineer and ETL developer in the regulatory reporting department of large financial institutions. I currently work full-time as a professional Quant Developer and have already invested many thousands of hours in R&D of financial markets and systematic trading strategies, building a deep knowledge of quantitative finance and algorithmic trading. Other remarks: My algorithms are always professionally designed and well documented, making them easy to follow. I mostly use the framework approach, so that the code is modular, pluggable and clearly structured, which also makes it much easier to perform adjustments or extensions. I am willing to sign a NDA, if desired, so that the intellectual property (IP) rights remain with you.
