Open to opportunities

    Hi, I'm Eslam SifeEldin

    Principal Software Engineer

    10+ years crafting scalable enterprise solutions with Spring Boot, Microservices, and Cloud Architecture

    About Me

    I build the systems that companies can't afford to have fail. My work spans Fortune 500 manufacturing clients and EdTech platforms handling 18+ million academic records. The pattern across my career: I inherit complex, often legacy systems and turn them into something the next team can actually maintain and scale.
