    I'm experienced in writing MATLAB scripts to model, simulate and control a wide variety of dynamical systems and create optimization routines. I'm also experienced with C++ and Python. One example of something I've done in C++ is using the open-source library PSOPT to solve an optimal ascent trajectory of a rocket launcher. In Python, I wrote a simple algorithm to count plants of images with the OpenCV library. I'm currently working on the simulation of satellite orbits, and the objective is to quantify how much error is inputted into the dynamical model by using a less accurate and decreasingly complex gravitational model. This project requires knowledge of C++, Python, and MATLAB.

    I am pursuing my Master's in Applied Mathematics and since the beginning of my undergrad I've been trying to develop a very horizontal, interdisciplinary formation, which is most organic to me since my interests span a wide range of -- often intertwined -- topics. My core technical interests are within the grand areas: Artificial Intelligence, Pure & Applied Mathematics, Theoretical Computer Science, Complex Systems, and Network Science. I have an extensive mathematical background and solid programming experience. A driving problem that could be said to be the connecting thread between all of these interests is that of further understanding "intelligence" as an emergent phenomenon that arises from the dynamics found within and between complex adaptive systems.

    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
