Hire a RAG Systems Engineer in Japan
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.
Japan’s market blends ultra-modern infrastructure with deeply entrenched legacy systems. Creating software for Japanese businesses requires immense attention to detail, complex character encoding support, and highly information-dense UI layouts. With minimal timezone difference between IST and JST, collaboration is nearly real-time. I deliver structured milestones with daily async updates and weekly demos.
