Back to original languageAbout Haytham
Senior Java Developer and Tech Lead with over 8 years of experience, specializing in Java environments (8 to 21), Spring Boot/Cloud/Batch, and the design of microservices and hexagonal architectures. Experienced in modeling and orchestrating complex business processes with Camunda (BPMN), as well as integrating and using generative AI solutions (LLMs, prompt engineering, RAG) within business applications.
Solid expertise in software engineering and DevOps (Docker, Kubernetes, Jenkins...), with a strong focus on designing robust, scalable, and secure distributed applications. Proficient in relational and NoSQL databases (PostgreSQL, MongoDB, Couchbase), continuous integration and deployment practices, and application security standards.
Accustomed to agile environments (Scrum), I combine autonomy, rigor, and technical leadership to solve complex problems and support project success, including use cases involving AI (automation, assistants, semantic search).
