    I am an experienced data scientist who has worked in Bioinformatics and Business analytics. I build automated trading strategies in my spare time. I've been programming in R daily for over 10 years and that's where I do most of my data analysis. I have a lot of experience with machine learning and data visualizations, mainly in R and Shiny. Working in a diverse set of fields has given me experience with many different types of data and obtaining it from many different sources. Thereby making me an excellent data miner, and knowing how to transform that data efficiently.

    Please also see my blog: jiddualexander.com I'm a data scientist / analyst and an expert R programmer. I am strong with ggplot (ggplot2 data visualisation) and I am also a Shiny App developer. I can create custom dashboards for your data with intelligent analytics and interactive graphics. I program in R 6 days a week and I am very confident with all aspects of a data analysis project. I use mostly the very powerful packages created by Hadley Wickham (data import, cleaning and tidying (tidyr), manipulation (dplyr), visualisation (ggplot2) and reporting (Shiny)). The list of online certificates (below) is a good indication of the focus of my skills. To understand the power of these tools for creating dashboards I suggest you take a look at RStudio's Shiny gallery (shiny.rstudio.com/gallery/). I have participated in the Master R Developer Workshop by RStudio, thaught by no other than Hadley Wickham himself. My expert knowledge in R extends to high quality functional programming, package building, meta-programming and more. I have a Master Degree in Theoretical Physics from Sussex University (UK) and very strong understanding of analytics and machine learning, including neural networks (which I studied at Uni), support Vector machines, RandomForest, Principal Component Analysis (PCA) and much more. Including the tools to train machine learning models I also have a fundamental understanding and set of tools to apply the correct models for specific situations. I'm also a Wordpress blogger, I'm not a Wordpress specialist but I do know specifically how to combine R and Wordpress and can help you post blogs directly from your R console with just a few lines of code.

    I graduated from the University of Macedonia, getting my degree in Finance, having acquired knowledge in various economics fields such as Finance, Statistics, Macroeconomics, and Marketing. I also graduated from the Master Program of Business Informatics of the Aristotle University of Thessaloniki. Last October, I completed my MSc in Complex Systems and Networks, in which I made heavy use of R to represent graphically statistical models and complex networks. My courses have focused on various specialist tools such as Business Intelligence, Data Analysis, Statistical Programming, creating Database Systems, and simulating economic models. These have helped me broaden my knowledge while showing me the diverse side of Computer Science combined with Economic Sciences, which I find fascinating. Currently, I work as BI Analyst in Carrie Beam Consulting and Alta Media Inc. I have also co-operated with Alpha Architect LLC, Firmographs LLC, DataCurry Inc., and R-exercises.com as a freelancer with a specialization in data visualization and statistical modeling projects using R/shiny, Qlk Sense, Tableau, and Microsoft BI via Upwork. As an author for R-exercises, I have published series of exercises and tutorials related to R packages like shiny, ggplot2, ggvis, Rmarkdown, Machine Learning methodologies, etc. As a person, I consider myself a perfectionist and passionate about precision and order. Attached you can find URLs of some of my Shiny projects. There are only parts of them that I had clients' permission to deploy and use as a portfolio.

    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.

    EXPERT-VETTED/TOP RATED - TOP 1% of FREELANCERS I am a Microsoft certified Data Scientist specializing in Power BI data visualization. I hold certifications in Power BI, Excel, Azure Machine Learning and Data Science. I completed my undergraduate studies at The University of Pennsylvania and The College of William and Mary. I have continued my studies of Data Science at Harvard and IBM, and my studies of Linux at Dartmouth. I realize that data is often complicated, but it doesn't have to look that way. I combine my experience in data analysis, visualization, and design with the awesome capacities of Power BI to make data understandable and beautiful. My Data Stories are crafted to communicate information in the clearest, most efficient manner. I believe that the more effectively the data is presented, the more easily the information is consumed. Power BI has fantastic capabilities that allow information to be presented in an appealing, clean style, yet still contain all of its intrinsic depth and complexity. From engineering the data to the finished dashboard, I make the complex approachable. I am experienced, professional, and I have a passion for what I do. I am pleased to offer complimentary consultations online or by phone. I can also provide you with a sample visualization of your data for a nominal fee. I look forward to learning about your project and I appreciate this opportunity. View my portfolio at: powerbidesign.com Best, Drew
