Data Scientist | NLP & Machine Learning Engineer | Python
$65.00/hr
I'm a PhD student with 6 years experience as data scientist designing, implementing and developing end-to-end machine learning systems for telecommunication, financials and insurance companies. Nowadays, my main interest is to look for ways to develop solutions in the area of natural language processing (NLP), text mining, data visualization and deep learning.
Skills summary:
➤ ETL knowledge to extract, transform and load data
➤ Data wrangling & scraping
➤ Exploratory data analysis
➤ Feature engineering
➤ Building machine learning and statistical models (both supervised and unsupervised)
➤ Tuning models
➤ Data reporting and visualization
➤ Making data-driven maintenance and continuous improvement of ML models
➤ Model deployment
Tech stack:
➤ Programing languages: Python, SQL, R and C.
➤ Machine learning frameworks: Pyspark, Pytorch, Scikit-learn, Textstat, Stanza, Huggingface, TensorFlow, Keras, Trax, NLTK, Spacy & Gensim.
➤ Visualization: Tableau, Matplotlib, Seaborn and Bokeh
➤ Cloud: AWS and Docker
➤ Others: Jira, Pytest, Git, Confluence and MLflow
Last Projects:
➤ Aspect based sentiment analysis for e-commerce.
➤ Analysis of novelty topics in social responsibility of top US companies
➤ Fake news detection of COVID-19 in Tweeter
➤ Customer churn estimation for telecommunication users (given text transcription of last phone calls)
➤ Text classification and topic detection system to identify business topics for call centers quality assurance.
➤ Dashboard development to translate the output of machine learning algorithms in business KPIs to support sales and customer retention teams in call centers.
➤ System to extract financial data and text entities from government contracts in PDF format.
➤ Process mining to detect temporal text patterns that increase the company ROI.
➤ Customer segmentation that estimates the purchasing power and performs risk assessment for a loan company.
I am a curious, analytical and methodological person who likes to understand the problem in-depth, formulate and validate hypotheses to solve problems.
