About Ziad Gholmish

Senior Software Engineer at Booking.com, Delivery Hero

Senior Android Engineer building scalable, user-centric mobile experiences across fintech and e-commerce at scale.I'm a hands-on mobile engineer with 10+ years of experience architecting and delivering high-impact Android solutions at Booking.com and beyond. I specialize in modernizing legacy systems, driving cross-platform initiatives (including KMP), and bridging mobile-backend collaboration to ship features faster and more reliably.At Booking.com, I've led critical migrations—from native to server-driven UI, Perl to Java backends, and hardcoded logic to dynamic, backend-powered systems—unlocking new capabilities for teams while improving app stability and user satisfaction. My work has directly contributed to a 15% increase in incentive-based bookings and a 20% reduction in bugs.I'm passionate about clean architecture, mentoring engineers, and solving complex technical challenges that create measurable business value. Outside of work, I've built and shipped Rafeki, a production KMP app serving real users on both Android and iOS.Currently based in Amsterdam, I'm eager to share what I've learned about mobile architecture, team leadership, and navigating large-scale codebases—and equally excited to learn from the community.
