Filip-Neo Anghel
aka. Lifip
Backend & Security Layer Developer
Started programming in 5th grade with Python and competitive problem solving. Shifted to cybersecurity in 9th grade — web security, offensive security, and vulnerability research. Co-founded Dacia Team with close friends from the cybersecurity community around Politehnica University of Timișoara. Work spans mobile security, AI-assisted pentesting automation, Windows endpoint-security research, open-source vulnerability discovery, and low-level research across Linux and virtualization attack surfaces. Also builds production cloud systems with Java, Spring Boot, GCP, Kubernetes, and AWS. In 2026, co-discovered CVE-2026-63939 — a high-severity zero-day in Valkey (CVSS 8.8, potential RCE).
