    Nice to meet you, my name is Bernardo and I'm a developer here in Brazil. For the past 6 years, I've been working with technology. My main skills are: - Python (Top Skill) - MQL5 (Top Skill) - Machine Learning (Top Skill) - SQL Server and MySQL - HTML (XML and JSON) - C++ I love challenging projects, especially in finance and investments. Some of my portfolio: 1. Algotrading Bot using Machine Learning models Briefing: The software was a ML model that could track all stocks traded on the market and predict when a big player was buying and selling a determined stock. Once it tracks a big player position, it automatically invested in that stock to flow with the price variation. 2. Software for predicting and betting in US Sports Briefing: Using Logistic Regression Models, the software could predict matches outcomes and evaluate if the Risk x Return of that game was good enough to bet on. If it tracked a good game, it will automatically bet on. 3. Multi-strategy bot for Metatrader5 - Technical Analysis Briefing: A White Box bot that compounds all technical indicators (and some more) of MetaTrader for multi-strategies variations. More than 1,000,000 possible combinations of strategies give the client a big opportunity to test many of his/her ideas of investments. I'm looking for a good partner that I could work with and help to develop his/her ideas! Contact me and let's take a virtual coffee to chat! Thank you, Bernardo

    I'm able to understand and apply Data Science and Technology to business and research projects. For the last couple of years I've been building and deploying data-driven products, and bridging the gap between business and technical areas, due to my generalist and interdisciplinary profile. My efficient communication skills allow me to understand and address stakeholders' needs, which is key to success for data science & machine learning projects. Selected Completed Projects: Predictive Model for Churn in Health Insurance Plans - 2020 Technologies: KNIME Analytics Platform, R, Docker, Metabase, PostgreSQL. A Health Insurance provider with tens of thousands of individual clients needs to be more assertive in customer retention efforts. I’m the team leader of an ongoing project to use Machine Learning to predict the probability of churn for each contract based on a history of 3.5 years of interactions and dozens of variables. We’ve explored and created new variables, selecting them by their relation to the target. The model was built and we deployed it as a web application running in docker inside the client premises. The probability of churn is currently being used by the customer retention team in production. I was the lead developer for this project. Optimization of Mental Health Surveys - 2020 Technology: KNIME Analytics Platform. The client wanted to decrease the burden of respondents by reducing the number of questions in surveys used to diagnose mental illness in corporate workers. I tested several Machine Learning models to predict the diagnostics based on partly completed surveys, detecting which questions could be removed without losing substantial accuracy compared to the completed survey. It was possible to reduce the number of questions by 20% and still have around 95% of accuracy on the diagnostic.

    I believe my strong science background has made me a very analytical, yet imaginative person. This means I excel at research and data analysis, drawing a substantial level of satisfaction from designing creative solutions to specific problems that only someone that has been forced to answer wacky physics questions for more than 5 years could. While I'm quite comfortable coding in Python and using its many diverse modules, I am also a quick learner with great ease for understanding the use of new tools and concepts. My services range from the tutoring or teaching of physics/math/programming related subjects, to data querying/mining for statistical analysis, to the development of tools and automated pipelines for data processing, including the use of machine learning techniques if necessary, and even the translation of English content to Brazilian Portuguese and vice-versa.
