I'm currently building a multimodal LLM agent platform for an oil and gas project. It's a multi-agent system on Pydantic-AI and LangGraph with MCP, hybrid lexical + semantic search in OpenSearch, QLoRA fine-tuning, vLLM serving and async microservices on AKS. I added a cross-encoder re-ranking stage that lifted MRR by 15% with no added latency. I also built clinical AI for oncology: a HIPAA-compliant RAG pipeline over patient history and pathology reports, computer vision for pathology slides, and on-device Android models via ONNX Runtime. At Cognaize I worked on document intelligence and semantic search over financial and regulatory filings, using bi- and cross-encoders and learning-to-rank (LambdaMART). I also moved inference to ONNX Runtime + Triton, which cut latency by 60%.
