Senior🎓
Top SchoolMohammed Belarouci is a Senior Software Engineer with 9 years of experience building production-grade AI and backend systems from Amsterdam. He specializes in turning AI proofs-of-concept into reliable, scalable services—most recently architecting an AI executive assistant that processes 100+ emails daily with a production RAG pipeline and >95% classification accuracy. His background spans large-scale platform work at Booking.com (driving a 90% performance improvement and creating a company-wide occupancy data library) to logistics optimizations at Picnic that cut trips and costs through algorithmic planning. Technically fluent across Java, FastAPI, event-driven microservices, Celery, Spark, Kubernetes and observability tooling, he emphasizes robustness, security and cost-aware model usage (LLM Guard, Langfuse). Known among peers as “the Javatar,” he combines hands-on implementation with system architecture and mentoring experience. Notably, he has a track record of converting research-level retrieval and ranking techniques (RRF, self-querying) into production value.
