First high-school cybersecurity initiative
I founded the first high-school-level cybersecurity initiative in my community. It focuses on awareness and on teaching students how security actually works.

Grade 12 · Addis Ababa, EthiopiaI break things to learn how they are built, then I design and ship the things that replace them. Security, code, motion and community, from a city where I once learned hacking from a video with no internet.

Before the
internet.
My older brother downloaded a low-quality ethical hacking video. I had no internet at home, so I watched it offline, one rough frame at a time. That was the first spark.
The picture was bad, grainy and tiny. It did not matter. The idea was clear enough to follow: computers have doors, and people can learn to find them.

Tools before targets2-bit and up
I made things
first.
Blender from Grade 2. Photoshop from Grade 3. Before cybersecurity, I was a self-taught creative who learned by opening the tool and breaking it until it made sense.
That habit never left. Design taught me to look closely at how something is put together. Security uses the same eyes, aimed somewhere less friendly. The torus is the first object every Blender student makes. This one is rendered live, and it gains colour levels as you scroll.

Then the
web came on.
After COVID, internet finally reached our home. I went deep into cybersecurity: NetworkChuck videos first, then local CTF competitions. I am a curious generalist who loves security, coding, design and helping my community through tech.

Doors I
found.
The superadmin door
I found a vulnerability in my school's management system that allowed superadmin login, and I reported it instead of using it. The school brought in the developer, who presented the issue to all of the school's directors.
My screen recording, reduced to 160 × 90 pixels and blurred. Nothing in it is legible, to protect student data.
INSA Cyber Talent Summer Camp
Selected for the 3rd batch as one of 300 students chosen nationally. This is where Etege Recon was built.
Ethiopia CyberShield CTF
Ranked 6th with team APT-04. In 2026 I competed in Ethiopian CyberShield again and our team placed 3rd. Watch the vlog.
Intro to Cybersecurity Tools and Cyberattacks
A structured foundation to sit beside the self-taught years: tools, attack types and the vocabulary professionals use.

Etege Recon V1
Built at the INSA camp with a team of three. A cloud-based automated web reconnaissance tool, delivered as a web app and a browser extension. It combines VirusTotal reputation, IP geolocation, leaked GitHub file search and an Nmap-style port scan into one report, with history and JSON export. I built the Python API.

Certificate Verification System
A system for my school's CS club (June 2026) so certificates can be checked instead of trusted.

Yahweh Nissi Fellowship tech
I run the fellowship's website and set up its domain email at yahwehnissifellowship.org.et, covering DNS, MX, SPF and DKIM, so the fellowship gets mail that arrives and is trusted.

Light, story and
live stream.
Volunteer graphic designer for Zetseat Youth and Yahweh Nissi Fellowship since January 2025. I design the event posters and motion pieces, program the lighting and set up the live stream, so what happens in the room reaches the people at home.

My goal is to study cybersecurity governance. If you need a secure thing, a sharp visual or someone who learns fast, say hello.
