    I have extensive experience in building Simulations, Algorithms, predictive Machine Learning models and whole software ecosystems with multiple algorithms working together. My expertise includes classic Algorithms, Statistics and Machine Learning, Simulation, Backed development, Mathematical Optimization, Data Science and Cloud Engineering. I also have a lot of expertise in creating solvers for combinatorial optimisation problems using local-search based meta-heuristics in the Optaplanner framework (now called Timefold). I have extensive experience with deploying this kind of software and the whole development cycle, including maintenance. I also do the setup and deployment of these applications on cloud infrastructure. I can complete the whole project pipeline or only do a specific part of the project. Up to you! My previous experience includes writing Algorithms for large companies dealing with dredging, pharmaceutics, manufacturing, delivery, workforce organisation, waste management, banking, financial trading and others. I created algorithms for these companies solving problems related to scheduling, routing, task-sequencing, route-optimisation, predictive modelling, quantitative analysis, automatic Algorithm configuration and Simulation. Some of these algorithms were implemented using Optaplanner, some were completely custom, some where done using machine learning and statistics (using Python and Python frameworks), some with Simulation, but most were a combination of some of these.

    *** 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.

    Since 2002 I have been employed at the Department of Economic Forecasting and Analysis at Wroclaw University of Economics. Currently at the post of an assistant professor. Although this work gives me a lot of satisfaction, I am looking for opportunities to test the suitability of my knowledge and skills (and maybe acquire new) in a real business. My current work is shared more or less equally between scientific research and teaching. In addition, occasionally I do expert analyses. I also own websites www.szandula.pl (a website for communication with students ) and www.wzory.info (portal featuring equations and tables used in different areas of science – as for now in the early stage). Both in my research and teaching work I use a number of different programs and programming languages such as: a) MS Office and Open Office family: Excel, Access, SQL, VBA; b) statistical and econometric software: Statistica, SAS, SPSS, R, OX, GRETL; c) computing environments: Matlab & Simulink, Octave; d) internet oriented: HTML, Webharvest , XPATH , JavaScript , BeanShell; e) graphics programs: Corel Draw, GIMP. RESEARCH The area of my research interests include mainly the theory of forecasting with particular emphasis on analogue methods, and time series analysis. In practical applications I mainly deal with the study of irregular cyclical fluctuations in the micro and macro scale. Earlier, I dealt with the demographic processes . I am the author of over 20 publications. In addition to publication in scientific journals I prepared and made available on my website workbooks using VBA macro for calculating analogue forecasts . TEACHING I hold both lectures, classes and computer labs. Since two years also in English. Up to now, I've been responsible for following courses: fundamentals of quantitative methods, mathematical statistics and econometrics, forecasting theory and computer simulation , forecasting and simulation , financial forecasting , financial analysis. I am the author of a prototype tool for automated checking students' knowledge of different courses. Macros written in VBA generate for each student individual set of exercises as well as their solutions. Student's solution is automatically checked . This system has been used successfully for 7 years in an increasing number of courses. It currently supports : financial analysis , mathematical statistics and econometrics, financial forecasting , fundamentals of quantitative methods. I plan to launch it on e-learning platforms. EXPERT ANALYSIS Occasionally I undertake expert analysis on demand. I have been involved in the preparation of, inter alia: - for the Wrocław City Office: forecasts of the development of different economic sectors in Wroclaw. - For the County Office of Złotoryja: statistical analysis of a survey on labor force participation of people with disabilities in the Złotoryja county. My task was firstly to write software using the language VBA and SQL to automatically obtain statistical measures for the desired queries and secondly to interpret some of the results. - For individuals: statistical studies of various surveys.
