Fix bugs & legacy
Untangle flaky systems and monoliths: diagnose, harden, and break them into maintainable, layered services without grinding delivery to a halt.
I don't just write code. I think about the whole system.
I'm Mustafa Gamal, a Senior Fullstack Engineer with 8+ years building secure, high-performance applications. At Breadfast I work on payment systems and was one of the first engineers on the Breadfast Card team, a regulated Visa product launched with ADIB Egypt and approved by the Central Bank of Egypt. I specialize in fintech integrations, clean backend architecture, AI-assisted development, and Arabic-first products.
