01.Who I am
About
Software engineer with 6 years’ experience building backend systems in Java (8, 17, 21) and Spring Boot, with a focus on microservices, event-driven architecture and enterprise system integration, developed test-first and run on Linux. I have shipped production software in regulated environments — digital banking at Bank Albilad, legal-tech claim processing at Flightright, cyber-security tooling at XSonardive — where correctness, auditability and secure integration matter more than speed alone. I work comfortably across the stack, pairing Spring Boot services with React and Next.js front-ends, and I ship mobile products end-to-end with React Native and Expo.
I work best in cross-functional Agile teams, and I care about the fundamentals: clean APIs, reliable integrations, solid test coverage, and systems that stay maintainable as they scale. I've delivered for companies across Germany, Saudi Arabia, and Australia — fully remote. Outside client work I ship my own products: two iOS apps built with React Native and Expo are live on the App Store.
