Welcome to my GitHub! I’m a Computer Science senior at Universidad Nacional de Colombia (GPA 4.3/5.0), graduating November 2025. I’m passionate about applying AI and privacy techniques to real‑world problems, from education technology to differential privacy, with hands‑on experience in full‑stack and research projects.

• Owlgorithm: A Python + Flask web app powered by GPT‑4o that guides Competitive Programming students through self‑explanation and reflection.
• Graph‑Neural‑GNN: Exploring oversquashing in Graph Neural Networks via Jacobian analysis and Cayley Graph Propagation on the CLRS benchmark.
• Differential Privacy: Implemented user‑level privacy constraints in statistical inference algorithms.

• Research Intern @ Purdue University
  August 2024 – February 2025
  • Built a GenAI‑driven tutoring app (GPT‑4o) for Competitive Programming education using advanced prompt engineering.
• Software Engineer Intern @ Twilio
  June 2024 – August 2024
  • Developed a Spring Boot service for global phone‑number geolocation across 10 + countries.
• Full‑Stack Engineer @ Universidad Nacional de Colombia
  April 2021 – July 2021
  • Created a Flask app integrating citation–database APIs to automate research‑paper metadata collection.
