I'm Omar Sabry, a backend architect with a passion for building scalable, high-performance systems. With over 2 years of experience, I specialize in creating solutions that are as elegant as they are efficient.
My expertise spans across API development and database architecture. I believe that great backend systems should be invisible - working seamlessly to deliver exceptional user experiences.
When I'm not coding, you'll find me exploring new technologies, contributing to open-source projects, or mentoring aspiring developers.
