About

👋 Hi there! I'm Mariangel Reyes, a data analyst and physicist. I'm passionate about teaching technical subjects, programming, academic research in astrophysics, and helping companies make data-driven decisions. I love creating new things that take me out of my comfort zone. A day where I learn something new is a successful day. In my current role at Mercantil Bank, I create data visualizations that tell a story about data integrity and have a call to action. I've also had the opportunity to develop my soft skills and teamwork abilities. My top skills include: ✨ Python ✨ SQL ✨ Grafana ✨ Power BI ✨ ML frameworks ✨ Reinforcement Learning with Human Feedback I'm always looking for ways to develop my skills. I recently completed the Machine Learning Engineer training program, which helped me gain a deeper understanding of the ML workflow. When I'm not working, I enjoy reading for hours, listening to podcasts, and studying. 📖 If you're interested in connecting or learning more about my work, feel free to send me a message. ✉️ angelsmreyes@gmail.com
