Computer Engineering student at UAH combining academic studies with 2+ years of active professional experience in high-responsibility environments. Working simultaneously as a Security, Lifesaving and Risk Management Specialist at Base Aerea de Torrejon and as a Swimming Instructor and Aquatic Coordinator at Humanitas Bilingual School — both roles requiring decision-making under pressure, team coordination, safety protocol supervision and technical communication in a bilingual (ES/EN) environment. Technically focused on concurrent and distributed systems (Java RMI, POSIX threads), advanced databases (PostgreSQL, Oracle, RBAC) and algorithms (Dynamic Programming, Backtracking, Branch and Bound). Analytical methodology grounded in a background in Astrophysics. |
