Top SchoolAlvaro Muñoz is a seasoned security researcher with 13+ years of experience uncovering critical vulnerabilities and hardening enterprise software, having held principal research roles at GitHub, Micro Focus and HPE and now based in Madrid. He combines deep application and web security expertise with hands-on exploit development and tooling—publicly demonstrating research at BlackHat, DEF CON, RSA and major OWASP events and responsibly disclosing RCEs in platforms like Microsoft, Oracle, Apache Struts and Spring. His work spans both research and engineering: contributing to high-profile open source projects such as CodeQL, Neovim and radare2, and enhancing offensive tooling like ysoserial.net and QIRA integrations. Trained as an MS engineer in Electronics and Telecommunication from Universidad Politécnica de Madrid, he pairs rigorous academic grounding with practical security impact across commercial and open ecosystems. An uncommon blend of offensive insight and developer-focused contributions means he not only finds bugs but also ships fixes and tooling that improve developer workflows and security scanning.
