Engineer. Founder. Builder.
I'm Mohamed Medjahdi, a Software & Cybersecurity Engineer and founder from Saïda, Algeria, focused on secure systems, Linux and system architecture. I diagnose root causes instead of patching symptoms.
I specialize in purple team operations, where offense meets defense: penetration testing and offensive tooling on one side, SIEM, detection engineering, threat hunting and incident response on the other, with Python and Go automating everything in between.
As an entrepreneur I run XpertVex, an AI platform that pressure-tests startup ideas before the first line of code. I also ship secure, AI-ready software for startups and teams.

Building XpertVex
Around 42% of startups fail for the same reason: they build something nobody wanted, and that mistake usually happens on day one, before a single line of code. XpertVex is built to catch it early.
You describe your idea, and in about three minutes it runs live web research and hands you a full report with an honest 0 to 100 viability score, backed by real sources you can check. Unlike a chatbot answering from memory, XpertVex searches the web and shows its work, then exports a PDF you can send to a co-founder or an investor.
every report includes
- Viability score, 0 to 100
- Market sizing
- Competitor breakdown
- SWOT analysis
- Customer insights
- Industry trends
