Data Scientist with Experience in Solving Real-World Problems

TOP RATED Data Scientist and Data Analyst Create the best Machine Learning algorithms to generate value to your business. I am going to offer you +5 years of experience in Data plus a masters degree to solve your problem from scratch to deploy and bring value to your business. Hard Skills: - Python (e.g., pandas, matplotlib, scikit-learn, TensorFlow, Keras,PyTorch) - R (e.g., Tidyverse, Caret, ggplot2, Shiny, sparkly) - BERT, GPT-2, GPT-3 - Big Data (Hive/Spark) - Servers (Linux/Bash) - SQL - Cloud Computing (AWS, Azure, Google Cloud) - Data Visualization (ggplot2, Dash, Plotly, matplotlib, seaborn) - Matlab - Geographic Information Systems (GIS) - QGIS, ArcGIS - JSON I have experience working with problems related to: - Supervised Machine Learning (e.g., Neural networks, Naive Bayes, Linear regression, Logistic regression, Support vector machine (SVM), K-nearest neighbor (kNN), Random forest) - Unsupervised Machine Learning (e.g., k-Means, Hierarchical Clustering algorithms, Autoencoder...) - Auto Machine Learning (AutoML) - Natural Language Processing (NLP) (e.g., sentiment analysis, keyword extraction, word embedding, text classification...) - Signal Processing - Customer Segmentation - Dynamic Pricing - Geostatistics and geoprocessing (e.g., Kriging, mapping, remote sensing) - Image classification - Dimension reduction (e.g., PCA, Factor Analysis, t-SNE) - In-depth data analysis (descriptive, inferential statistics and multivariate analyses, such as linear regression, ANOVA, MANOVA, MANCOVA, cubic splines, CCA, RDA, t-test, Mann-Whitney, Kruskal-Wallis...) I am a native Portuguese speaker, fluent in English.
