About Me
Since 2021 I've been a backend developer at Foo Ag in Berlin, designing and maintaining backend services and REST APIs for financial applications in Symfony and PostgreSQL — from data-extraction pipelines that normalise heterogeneous document formats into one domain model, to the AI layer of an internal product architected under EU data-residency constraints.
Before that I taught web development to career changers at ReDI School Berlin and tutored undergraduates in C and Assembly at TU Berlin, where I earned my B.Sc. in Computer Science.
Communication is key — I work in German and English (both C1) and Arabic, my native language.
