Constructing robust systems with Java Spring Boot, React, and low-level C architecture.
ABOUT
I am a 5th-year Computer Science student at the Open University of Israel, specializing in backend architecture and high-performance systems. My passion lies in bridging the gap between complex algorithms and intuitive user interfaces. From low-level memory management in C to scalable microservices in Java, I build digital products that are fundamentally robust.
