Swiss-Army-Knife Python Developer for Data Science, Analytics and AI

A former microelectronics engineer who found out that the best way to build and innovate is with a laptop 💻. With over 3 years of expertise in Python programming, I've worked in various fields, including Data Science, Data Analytics, AI, and Automation. My multilingual skills in Portuguese, Spanish, French, and English 🌍 make me a global collaborator, allowing me to work seamlessly with international teams. Notably, I've worked as an IT professional at the European Spaceport in French Guiana, where I introduced new development tools, digitized several departments, and bridged the gap between French Guiana and Toulouse headquarters. Cool Projects I've Built 🛠 ⭐ RAG system chatbot: Built a chatbot using Ollama, Langchain and Chromadb. The user gets the newest data related to crypto, web3 and blockchain. ⭐ AI Books: Created a partially automated repository using FLUX.1 API, LLMs, and custom functions to generate illustrated books based on fine-tuned models of my family and friends. ⭐ Automated Web3 Newsletter: Built a workflow that scraped data from web3 publishing platforms, preprocessed insights, and created a weekly report with charts. I also developed an online platform with Flaks and Plotly for subscribers. Data Science Projects 📊 ⭐ Dubai Real Estate Sales Forecasting: Predicted sale prices using a random forest regressor model, achieving an R-squared value of 0.86. ⭐ Crypto Sentiment Analysis: Used VADER sentiment lexicon tool to predict sentiment of crypto tweets, with additional data cleaning and custom lexicon creation. ⭐ Prevent Transportation Risks: Predicted temperature and humidity inside transportation vehicles using regression models and IoT sensor data. ⭐ Analyze GitHub Development Activity: Used Exploratory Data Analysis (EDA) to understand GitHub activity of several Crypto AI projects. Skills & Tools 🛠 ✅ Web Scraping: Proficient in Scrapy, Beautiful Soup, and Playwright, with experience tackling complex websites like Facebook, Amazon, and YouTube. ✅ Machine Learning: Eager to share my portfolio of machine learning reports, including regression, classification, and sentiment analysis using Scikit-Learn, Pycaret, and TensorFlow. ✅ Data Visualization: Skilled in creating compelling visualizations with Matplotlib, Seaborn, Vega-Altair, Plotly, and Dash, from simple charts to dynamic visualizations. ✅ Web Development: Can develop robust Flask applications that complement data services. ✅ Technical Writing: Articulate complex topics in Data Science, Data Engineering, and AI, simplifying them for wider audiences. ✅ AI tools: I can help you create your RAG system using OpenAI, Ollama, Langchain and vector databases.
