About Abdelhamid

Full-stack software engineer specialized in applied AI and LLM integration into business applications. Expert in C#, .NET, JavaScript, and frontend development (Angular, WPF, Avalonia) as well as backend (REST APIs, modular architecture). I integrate language models (LLMs), RAG (Retrieval-Augmented Generation) systems, and design autonomous agents (Agentic AI) to automate complex business processes. Also experienced in setting up Machine Learning pipelines and using MCP (Model / Memory / Compute / Planning) related technologies.

Good command of SQL/NoSQL databases, application security, and distributed environments. Agile project management (Scrum/Kanban) with coordination of multidisciplinary teams and results-oriented leadership.

Curious, proactive, and solution-oriented, I adapt quickly to new environments. Bilingual in French/English, I enjoy working in collaborative, innovative, and international contexts.
