Hi, I'm Adrián Feito Blázquez
From ranking top 100 worldwide on Hack The Box to architecting scalable backend systems, my career is defined by a fascination with how software behaves at its technical limits. Currently a Computer Engineering student and Software Architecture intern, I am focusing my professional development on High-Performance Computing (HPC) and Systems Engineering, treating C++ as a precision tool for low-level optimization and memory safety. By strictly adhering to the Google C++ Style Guide, I merge an adversarial security mindset with rigorous architectural patterns to build software that is as computationally efficient as it is robust.
