What I'm looking for

I seek senior roles where I can lead red team operations, secure cloud and web platforms, build automation tooling, and mentor teams while influencing strategic security decisions.

I am a highly accomplished penetration tester and security officer with extensive experience identifying and mitigating complex vulnerabilities in financial and blockchain systems. I lead Red Team engagements, run emergency penetration tests, and simulate advanced persistent threats to strengthen organizational defenses.

I build custom tooling and automation using Python, Rust, Go and other languages to accelerate vulnerability detection, reporting, and remediation. I have secured modern web services and large-scale cloud infrastructures across AWS, Azure and GCP, and integrate SAST/DAST pipelines into development workflows.

I communicate complex technical risk clearly to technical teams and senior executives, turning findings into prioritized mitigation strategies and actionable briefings. My work includes creating C2 tooling, Cobalt Strike payloads, and bespoke red team frameworks to test and improve real-world resilience.

I hold certifications including CISSP, OSCP and AWS Security Specialty, founded the OWASP Barcelona chapter, and have a track record of training developers and delivering secure infrastructure and application projects that measurably reduce organizational risk.
