Back to original languageAbout Wassim
With over 10 years of experience, I design and evolve critical information systems, particularly in real-time data, distributed systems, and architecture modernization.
I work on IS redesign and transformation projects, aiming to move legacy environments to scalable, resilient, and event-driven platforms capable of meeting high performance and volume challenges.
🚀 Today, I integrate Artificial Intelligence into this dynamic, developing solutions around RAG, local models, and advanced automation, to exploit data more intelligently and create new business levers.
💡 My approach: converge data, architecture, and AI to build systems that are robust, scalable, and high-value.
I pay particular attention to the quality of architectures, performance, observability, and solution industrialization.
🤝 Committed and impact-oriented, I work in Agile environments with a strong culture of collaboration and continuous improvement.
