About

Developer by trade,
traveller by design.

For 15+ years at agencies serving 1,000+ nonprofits and associations, I've been the person who takes a design and makes it real: fast, secure, and accessible to everyone. I've led multi-developer builds, played a key role in engagements past $200K, and redesigned a WordPress workflow that cut build times by 40%.

These days I'm pairing that experience with AI-assisted workflows. I'm an Anthropic-certified developer applying Claude to ship better, faster. Bilingual in English and Arabic.

When I'm not shipping websites, I'm out collecting countries: 68 so far, with my sights set on 100.
