Data scientist and software engineer with background in physics, data mining, database administration, and web development. Interested in all realms of artificial intelligence and modelling; including machine learning, scientific analysis, game AI, computer vision, neural networks, NLP, robotics, etc.

Technical Skills

Python, SQL, C#, Javascript, HTML, SASS

Pandas, Scikit-learn, Plotly, XGBoost, Django, React

Visual Studio Code, Jupyter, MS SQL Server, PostgreSQL, AWS Console

Technical Projects

Filmophile - Github

Scraped data from movie information and streaming service websites with selenium package

Engineered several features as a mix of the same column from different data sources, applying one-hot and multi-hot encoding to categorical columns

Searched for the best classifier among: logistic regression, naïve bayes, KNN, random forest, SVM, xgboost

Tuned support vector machine (sklearn sgdclassifier) to improve accuracy by 6%

Regression for Pricing of Lego Sets - Github

Scraped Lego set data with requests and beautifulsoup libraries

Tuned a linear regression regularization model to predict the price of a new Lego set with a R2 of 0.86

Preserved the interpretability of beta-coefficients in order to construct a symbolic mathematical model

Classification for Profitability of New Lego Sets - Github

Processed the columns of the Lego data set to engineer new coarse-grain features and the target variable

Trained logistic regression with different solvers and regularization for a baseline accuracy of 78%

Tuned a random forest with grid search of hyper-parameters to improve accuracy to 80%

Changed the balance of input classes with the imblearn pipeline using under sampling and SMOTE
