About me
Intro
As the CTO at SuperIntro, I lead the development of an AI-powered matchmaking platform using LangChain, GPT-4o, and RAG pipelines, achieving a 30% improvement in match accuracy. I oversee a small development team, enabling seamless multi-environment deployments on GCP Cloud Run, and optimizing performance with Next.js 15. These efforts have strengthened the platform’s scalability and user engagement. With a bachelor's degree in Computer Science from the Private University of Marrakech, I bring expertise in React.js, Node.js, and LangChain. My work at SuperIntro and previous roles at Dropify and LoftyService highlights my commitment to building scalable AI-driven SaaS products that solve real-world challenges. My goal is to create innovative solutions through clean architecture, agile practices, and collaborative development.
