I'm David Sandoval, a Computer Science student at the Escuela Superior Politécnica del Litoral (ESPOL), a university internationally accredited by ABET and EUR-ACE. I'm passionate about data, artificial intelligence, and software development, and I've worked with Pandas, NumPy, Scikit-Learn, Seaborn, Streamlit, Node.js, Django and n8n.

Right now, I'm working toward certifications as a Data Engineer, Data Analyst, and Data Scientist through DataCamp, and I'm also exploring Google Cloud certifications. My goal is to grow into a well-rounded data professional, combining analysis, engineering, and science to deliver innovative solutions to real-world challenges.
