Lead Front-End & Mobile Engineer
Majid Aljishi
9+ years architecting high-scale Expo, React Native & Next.js applications. Leading front-end teams and building enterprise-grade experiences for the KSA market.
About Me
Who I Am
I'm a passionate Lead Engineer based in Dammam, Saudi Arabia, with a deep love for crafting pixel-perfect, high-performance mobile and web experiences. With over 9 years in the industry, I've had the privilege of leading front-end teams at Zain Saudi Arabia, one of the kingdom's largest telecom providers.
My journey started in electronics engineering, which gave me a unique low-level understanding of how systems work. That foundation, combined with my expertise in React Native, Expo, and Next.js, allows me to build applications that are not only beautiful but also blazingly fast and scalable.
Beyond code, I'm driven by automation and developer experience — from custom CI/CD pipelines with Fastlane to Jira-integrated build systems. I believe great engineering is about empowering teams to ship confidently and continuously.
