Bramwel O.

I build end-to-end Multimodal AI Agent systems, enterprise RAG backends, and cloud-native AWS infrastructure from the ground up across Voice, Text, and Video/Vision modalities. I specialize in designing resilient, production-ready GenAI architectures—combining real-time conversational Voice AI (WebRTC / Low-Latency APIs), stateful multi-agent workflows (LangGraph), computer vision / video processing pipelines, and Knowledge Graph-augmented retrieval (GraphRAG). Whether you are launching a new multimodal platform from scratch or optimizing existing infrastructure to reduce latency, fix execution loops, and scale inference, I bridge advanced LLM orchestration with robust cloud engineering.
