About Me

Hacker by passion.
Builder by mission.

I'm Yohanes Mesfin, known online as EYOHE — an ethical hacker, red teamer, and web security specialist based in Addis Ababa, Ethiopia. I live and breathe cybersecurity, spending hours hunting vulnerabilities, breaking things apart to understand how they work, and building more secure systems.

My journey into cybersecurity started with curiosity and grew into a relentless pursuit of knowledge. From mastering offensive security techniques on TryHackMe to performing real-world web security assessments and bug bounty research, I'm constantly sharpening my skills on the digital frontier.

Beyond hacking, I'm an entrepreneur and startup founder. I built TrustBridge ET — a cybersecurity and technology startup focused on empowering Ethiopian businesses with world-class digital security. I believe technology should serve people safely, and I'm on a mission to make that a reality across Africa.
