I'm Pepe — a Ph.D. Candidate at CISPA Helmholtz Center for Information Security in Saarbrücken, Germany, originally from Seville. I research systems security and fuzz testing, which basically means I spend my days trying to break software in interesting ways.

• 🔭 Currently building Fandango, an open-source language-based fuzzer that generates structured, semantically valid test inputs at scale.
• 🔬 My research covers fuzzing, vulnerability research, protocol testing, XML injection, and GNSS security testing. Always exploring new ways to stress-test complex systems.
• 🌍 I've presented in a number of conferences, spent three months as a visiting researcher at the Max Planck Institute for Security and Privacy in Bochum, and attended summer schools in Singapore and Bergamo.
• 📚 Before CISPA, I studied Software Engineering at the Universidad de Sevilla — Bachelor's and Master's, both with Honors Distinction.
• 🤝 Always open to collaborating on open-source security and testing projects — feel free to reach out!
