Full-stack Engineer • Freelance Developer
I design and build reliable full-stack systems for local and international clients, from internal tools to customer-facing platforms, turning real-world requirements into clean, maintainable, and scalable products.
I’m a full-stack developer with experience in delivering production systems for both local and international clients. My background covers mobile applications, web and desktop platforms, secure banking-style systems, bidding and auction platforms, and multi-tenant lost & found ecosystems for cruise lines, airports, and other businesses.
I have completed all modules of the BSc (Hons) in Software Engineering from Birmingham City University (yet to receive the final transcript & certification - expected in July 2026) and enjoy turning business requirements into dependable, well-architected solutions. From backend APIs and databases to frontend engineering and cloud deployment, I focus on clean design, maintainability, and real-world impact.
A selection of freelance, academic and personal projects that demonstrate my full-stack and cross-platform experience with skills in different techs and languages.
