The job is fully on-site in Saudi Arabia—our servers are air-gapped—so I need someone already in the country who can sit with the team, dive into the containers, and restore relevance. You will first trace the root cause of the drift (distance metrics, collection parameters, sharding, embedding pipeline or anything else at play). Once pinpointed, you’ll apply a durable fix within the existing Docker-compose setup and then verify the outcome through quantitative testi...
