01 · About Me

Who I Am

Senior Cybersecurity student at Marymount University (CAE-CD), graduating December 2026. Bilingual — fluent in English and Arabic.

In 2023, I founded DOSCARS US LLC — an independent wholesale dealership specializing in the global export of exotic and luxury vehicles. I built the entire digital platform myself.

With the right AI tools, I operate as a complete product team — from concept through architecture, development, testing, security, and deployment.

How I Work

🌍
Bilingual & Global
Fluent in English and Arabic. Manage international clients across U.S., Middle East, and global markets daily. Cross-cultural communication is built into how I operate.
🚀
Entrepreneurial Execution
Founded and run a real business — not a class project. I handle sales, operations, compliance, technical infrastructure, and client support simultaneously.
🛡️
Security-First Thinking
Every system I build starts with: what's the threat model? Encryption, access control, secure defaults, and hardened infrastructure are non-negotiable.
🤖
AI Fluency
I use AI tools to amplify output, not replace thinking. Prompt engineering, AI-assisted development, and agent design are part of my daily workflow.
🔄
Adaptable
I've operated across security, development, QA, product management, and operations — often all in the same day. I adapt to whatever the work requires.
📋
Self-Managed
Running a solo business requires discipline, prioritization, and accountability with no one to delegate to. That translates directly to any team environment.
