About Omar Chimère
I help companies create measurable value with AI by designing, building, and deploying production-ready ML systems. As an AI Tech Lead & ML Engineer, I’ve delivered solutions on GCP and Databricks that reduced fraud-related revenue risk by over 2×, cut manual intervention in dispatch operations by 30%, and increased average order value by 7% through personalized recommendations. I specialize in MLOps, cloud-native AI, NLP, and Generative AI, building scalable, reliable systems that drive real business outcomes.
Beyond implementation, I mentor teams and lead end-to-end AI initiatives, spanning credit scoring, visual defect detection, chatbots, and AI-powered content pipelines. I support clients from strategy to deployment, helping them operationalize AI and grow their internal capabilities.
