About Joel

Cybersecurity professional with over 5 years of experience, holding certifications such as OSCP, CRTP, and CARTP. Throughout my career, I have participated in numerous bug bounty platforms and CTF challenges like HackTheBox. My professional experience has been enriched by involvement in several Red Team exercises, conducting a wide range of penetration tests, web and mobile audits, and Purple Team exercises. I have worked with both SMEs and multinational Spanish and foreign companies.

Passionate about my work, I stay updated with the latest cybersecurity trends and technologies, offering advice on software and infrastructure, and performing malware and phishing analysis.

My interest lies in participating in Red Team exercises, with a particular focus on physical intrusion; conducting penetration tests on websites and mobile applications; and advising on the design of secure network infrastructures and software projects.
