edX Verified CS50x
An intensive, foundational program exploring the core principles of computer science and software engineering, led by Harvard University
Cambridge English Level C2 Proficiency Certification
Awarded the Certificate of Proficiency in English (Grade C) by Cambridge University Press & Assessment, officially demonstrating a Council of Europe Level C2 mastery of the English language. Achieved an overall score of 211 in the June 2025 examination, validating an ability to communicate with fluency, sophistication, and accuracy that approaches that of a native speaker across academic, professional, and social environments
Erasmus+ Academic & Cultural Exchange Program | Florence, Italy
Participated in an Erasmus+ Group Mobility program focused on cultural immersion, environmental awareness, and European history. The mobility involved attending academic classes at the I.I.S. G. Peano in Florence, living with a local host family, and participating in experiential learning tours across Florence and Pisa. Additionally, the program included a hosting phase in Valencia, Spain, which required co-developing digital presentations in English and acting as a cultural guide for visiting Italian students
NASA-Supported Research Initiative | The Fairchild Challenge
Collaborated on a high-density, classroom-based botany and space crop research project for the Jose Marti MAST 6-12 Academy, sponsored by the Fairchild Tropical Botanic Garden in partnership with NASA’s Kennedy Space Center. Spearheaded the rigorous data collection and empirical testing protocols that earned the team a Special Merit: Statistical Analysis distinction. By designing and evaluating plant growth metrics under conditions mimicking the International Space Station's Vegetable Production System (Veggie), the research contributed valuable predictive data to NASA's Space Crop Production team. The exceptional analytical quality and accuracy of the submission secured a structural first-place tie overall, winning a $1,500 grand prize check to fund the school’s ongoing environmental and STEM programs
Introduction to Java Certification | Sololearn
Successfully completed the "Introduction to Java" course via Sololearn, demonstrating both theoretical and practical proficiency in the core concepts of Java programming. The curriculum validated foundational software development competencies, object-oriented programming (OOP) principles, syntax fundamentals, and basic algorithmic problem-solving.
