    Eslam SifeEldin

    I've spent most of my career picking up systems that were stuck and getting them unstuck. Right now I'm replatforming a 15-year-old Rockwell manufacturing system to Spring Boot 3 microservices at Integrant.

    Before that I worked on Parchment, a credential exchange platform that handles 18.5M+ academic records for 15,000+ institutions. FERPA-compliant pipelines on AWS, high-uptime requirements, no room for mistakes.

    10+ years of Java in production. Spring Boot, AWS, Kubernetes. I know how to take a legacy codebase and turn it into something the next team can actually work with.
