Alae Guessous

I've led Java modernization and integration work across high-volume payment, healthcare, real estate, and CRM systems for eight years.

At Alten for Worldline, I led the redesign of a business module handling high-volume flows and batch processing. I built resilient messaging capabilities with retry mechanisms, traceability, and error recovery, while modernizing Spring Framework applications to Spring Boot and modularizing them.

At Djiin by Sereneo, I led the platform's Java engine, refactoring and modularizing it in preparation for a microservices migration. I also implemented feature toggling for safe deployments, optimized the core engine, and provided technical mentoring and customer support.

Earlier, I progressed from Software Engineer to Technical Designer and Technical Lead on healthcare management solutions, including a patient self-service pre-admission kiosk. I've supported production during the Covid-19 pandemic, developed an internal JSON-based integration testing framework, contributed to the INSI certification project, and mentored teams through code reviews and development practices.
