I'm Emmanuel Declan (Cypher), a cybersecurity student building practical skills in offensive security. I'm currently focused on Linux, networking, web application security, penetration testing, Python and security reporting. I learn by building, breaking, experimenting, and documenting what I discover along the way. My target role: Junior Pentester / SOC Analyst / Security Analyst.
