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.Machine LearningArtificial IntelligenceSystems ModelingSystems SciencePrompt EngineeringScientific WritingNetwork AnalysisJuliaScientific ResearchMathematicsPyTorchPythonData Science - $100 hourly

I am a seasoned Data Scientist and Researcher with over seven years of experience, holding a Ph.D. in Cognitive Science and computer modeling. Just on Upwork, my professional journey is marked by a diverse portfolio of more than 25 successful projects, accumulating over $40K in earnings and dedicating 770 hours to deliver top-notch solutions, achieving a 100% job success rate. As a Top Rated Plus freelancer, I have demonstrated unparalleled expertise in Python programming and deep knowledge of libraries such as Pandas, Numpy, Matplotlib, Scikit-learn, Tensorflow, and Pyunicorn. My specialty lies in temporal series analysis, with a strong emphasis on Energy Disaggregation, predictive maintenance, and predictive diagnosis. Beyond private sector achievements, I have spearheaded numerous projects in stock market prediction, image analysis using deep learning, and reinforcement learning, showcasing my ability to lead and innovate in complex data-driven initiatives. Whether you're seeking expertise in data analysis or looking for a leader to bring groundbreaking projects to fruition, I bring a wealth of experience and a track record of success to every endeavor. IMPORTANT! Before contacting me ask yourself: 1. Do I have the necessary data for this project? (I'd very rarely be able to provide data for your project.) 2. Is the data suitably prepared for a machine learning project? (If not, there will necessarily be a stage for EDA and ETL which normally takes some time.) 3. Is it really feasible given the current machine learning state-of-art? (Some ideas are simply either too far from reality or demand a large amount of investment for becoming real.) 4. Do I have enough budget to afford this project? (Be realistic about the project you're proposing.) My mission is to provide you with a model that can meet your expectations, but the expectations should be realistic - and that's why I have 100% of success in my projects!Machine LearningGoogle Cloud PlatformArtificial IntelligenceData AnalysisGISNeural NetworkArtificial Neural NetworkImage ProcessingComputer VisionTensorFlowDeep LearningModel OptimizationKerasNatural Language Processing - $10 hourly

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!
