Abd Elrahman S.

Lead Software Engineer / Mobile App Developer

I’m a Lead Software Engineer with extensive experience designing, building, scaling, and maintaining production-grade software across mobile, web, SaaS, cloud, and backend systems. I specialize in taking products from idea to production and, just as importantly, taking over existing codebases, understanding complex architectures, fixing critical issues, and turning them into stable, scalable, and maintainable systems. As a lead engineer, I’m comfortable owning the entire technical lifecycle — architecture and technical decisions, development, third-party integrations, backend systems, databases, CI/CD, cloud deployments, performance optimization, debugging, security, and App Store/Play Store releases. What I bring to a project Lead-level technical ownership and architecture decisions Cross-platform & native mobile development Full-stack SaaS and web application development Backend, API, database & cloud architecture Third-party API and platform integrations AI-powered features and automation Legacy codebase audits, debugging & modernization Performance, scalability and reliability improvements Production deployments, CI/CD and DevOps App Store & Google Play release management Technical problem-solving from requirements through production I focus on building software that is not only functional, but reliable, scalable, maintainable, and ready for real users and real business requirements.
