Hi, My name is Samuel Tesfamariam, a data analyst living in the United States. I have a Master's degree in Economics with a concentration in Forecasting and a Bachelor's degree in Economics and Business Management with a focus in Finance. I am a lifelong learner and data analytics enthusiast. Check out my projects on my Github. (Samuel's Github)
I am skilled in data manipulation, data analysis, data visualization, statistics and predictive modeling. My toolkit includes, but is not limited to, Python (Numpy, Pandas, Matplotlib, SickitLearn), SQL, R, SAS, EViews, Tableau, Power BI, and Excel.
In this project I implement an end-to-end machine learning model deployment. I use the Boston House Pricing dataset from sklearn. I fit a regression model to estimate the parameters and make predictions. I build a Web App using Python's Flask framework and deploy the app on Render.
In this project I use ATP Tennis Players data and machine learning techniques to select optimal predictors of players' earnings. I investigate the best predictors to include in my linear regression model through different feature selection methods (Filtering and Sequential Feature Selection) I explore two different model testing techniques: Validation test set and K-Fold Cross Validation test.
In this project I take Housing data from Nashville, TN and clean it for analytics usage. I apply different SQL statements, such as SUBSTRING, Conditional statements, Window Functions, and utilize CTE (Common Table Expression).I use SQL Server.
In this project I use Time Series analysis techniques such as ARIMA modeling, Augmented Dicky Fuller test and others to predict the Global Metal Price Index.
In this project I conduct data exploration techniques on global data on Covid-19 infection and death counts by country and continents. I construct "VIEW" tables for data Visualizations use. However, since the free Public Tableau does not connect to a database I use Excel workbooks to visualize the data and create the dashboard.
Here you will find all the Tableau dashboards I will be working on. This is a place I can showcase my creativity in data driven storytelling.
