What Sets Me Apart
AI-First Developer
Early adopter of AI coding tools (Cursor, Windsurf, Antigravity) delivering 35% faster while maintaining 95%+ test coverage—I don't just use AI, I integrate it strategically into development workflows for maximum impact
Architect, Not Just Developer
I design systems thinking 2-3 years ahead—considering scalability, security, maintainability, and team velocity from day one. My solutions don't just work today; they evolve with your business
Business Impact Obsessed
Every line of code ties to a business metric: 40-70% performance gains = happier users and lower infrastructure costs. 60% fewer bugs = faster feature delivery. 25% less cart abandonment = direct revenue increase
Technical Leader & Mentor
I elevate entire teams through code reviews, documentation, and knowledge sharing. My junior developers become senior developers. My codebases become maintainable assets, not technical debt
Modern Stack Pioneer
While Drupal is my foundation, I bring cutting-edge tools: TypeScript for type safety, NestJS for scalable APIs, AI for productivity, comprehensive testing for reliability. I bridge 'traditional CMS' with 'modern architecture'
Bilingual Technical Communicator
I translate between technical teams and business stakeholders in English, French, and Arabic—ensuring alignment, managing expectations, and delivering results that matter
