Hi, my name is Emmanuel.
I'm a Cybersecurity Specialist grinding Hack The Box, hunting threats, and building security tools. HTB Rank: Hacker.
Cybersecurity Enthusiast
📍 Philippines
A passionate cybersecurity professional diving deep into ethical hacking, threat analysis, and digital forensics. Currently grinding on Hack The Box, sharpening offensive and defensive skills one machine at a time.
My mission: protect, detect, and respond — turning vulnerabilities into lessons and threats into defenses.
Joined my first inter-school coding competition. Competing under pressure, solving algorithmic problems on the fly — this was the spark that ignited everything.
Competed in hackathons and a mobile app development competition. Built real apps under tight deadlines — learning to ship fast and collaborate under pressure.
Developed and defended a capstone research project. Applied technical skills in a real academic context, collaborating with BFP and institutions.
Built and launched real-world startup apps — TraysiTek and HatidGo. Designed, developed, and shipped products from scratch.
Joined Hack The Box, earned certs, and went deep into pentesting, web security, and DFIR. Still hacking. Always learning.
Completed 24 days of hands-on cyber security challenges covering web exploitation, DFIR, network analysis, and reverse engineering. Demonstrated consistency and breadth across multiple security domains.
✓ VERIFYHands-on penetration testing certification validating skills in network scanning, exploitation, pivoting, and web application attacks. Completed a full simulated pentest engagement to earn this credential.
✓ VERIFY8-course professional certificate covering security foundations, network security, Linux, SQL, SIEM tools, IDS, and Python automation. Completed through Coursera with hands-on labs and capstone projects.
✓ VERIFYCredential awarded upon completing Cisco's Ethical Hacker course, covering methodology, penetration testing, social engineering, exploit techniques, wireless attacks, and post-exploitation reporting.
✓ VERIFY— Websites
