AI & Machine Learning · Port Harcourt, Nigeria
Hire a RAG Systems Engineer in Port Harcourt
I build enterprise Retrieval-Augmented Generation (RAG) pipelines that turn fragmented company documentation into accurate, hallucination-resistant knowledge bases. Utilizing Supabase pgvector, hybrid search, and semantic re-ranking, I deliver high-precision enterprise AI.
Port Harcourt’s economy is deeply rooted in the energy sector but is rapidly diversifying into tech. Software built for this region often involves enterprise resource management, logistics tracking, and robust offline capabilities for field operations. I have hands-on experience shipping production systems for African markets, including FluxDial's telephony infrastructure in Nigeria and JDL Solicitors' digital platform. I understand local integration challenges, payment rails, and user expectations firsthand.
