What I'm looking for

I'm looking to lead and build scalable backend, mobile, and web products while mentoring engineers, improving delivery practices, and connecting technical decisions to business outcomes.

I've led the development of SINNTS at Afri Lab AI / Sinnts, spanning Flutter and React Native mobile applications alongside Node.js and NestJS backend services. I balance hands-on architecture, code reviews, and delivery with team coaching, planning, and budget management.

At Commercial Bank of Qatar, I developed Flutter mobile features and integrated scalable Node.js/NestJS APIs for peak banking demand. At MIRA General Marketplace, I improved backend response times by 40%, reduced transaction failures by 20%, and delivered 90% test coverage.

I've also led cross-platform mobile teams at Hawkish Group, built web and mobile applications with React and Node.js, and trained more than 50 students in app development. I use Clean Architecture, TDD, CI/CD, and practical collaboration to ship reliable software.
