# About Me
I'm Younes Tito (V7x / Vairous7x) — a full-stack software engineer and cybersecurity specialist with 18+ years of experience since 2008. I design, build and ship complete products end-to-end — mobile, desktop, web and cloud backends — and harden them against real-world threats with a threat-model-driven, DevSecOps mindset.
Founder, team leader and lead instructor of V7x Academy — the largest Arabic-language cybersecurity learning platform (4.9★, 150k+ downloads) — and creator of the V7x / Vairous7x channels with 22M+ views and 500k+ followers. My work spans full-stack engineering, DevSecOps & system hardening, security research, OSINT, web & network security, AI / LLM integration, and large-scale SaaS, POS and fintech systems. Trusted partner of ANY.RUN, OrcaVPN and FloopyData.
