Danuka T.

I’m a Senior AI Engineer specialising in production Generative AI, LLM agents, RAG systems and applied machine learning. I’ve built and deployed AI systems across organisations including Airbus, Argus Media and Nationwide Building Society, covering everything from research prototypes to secure enterprise-grade AI applications. What I can help you build: • AI Agents & Agentic Workflows Multi-agent and tool-using systems with LangGraph, Google ADK, MCP and structured workflows. • Production RAG Systems End-to-end retrieval pipelines using hybrid search, vector databases, reranking, Self-RAG, HyDE and corrective RAG techniques. • LLM Evaluation & Reliability Evaluation pipelines covering faithfulness, context precision, retrieval quality, hallucination detection and human-in-the-loop feedback. • Secure Enterprise GenAI Production AI systems with authentication, APIs, cloud infrastructure, observability, CI/CD and controlled access to proprietary data. • LLM Fine-Tuning & Alignment LoRA/PEFT, TRL, preference optimisation and RLHF techniques for adapting smaller models to specialised tasks. • Applied Machine Learning PyTorch, TensorFlow, JAX, XGBoost, uncertainty estimation, explainability and reinforcement learning. Selected experience: • Built RAG systems achieving >91% faithfulness and ~90% context precision. • Developed an MCP-based platform for securely exposing proprietary data to AI applications. • Built agentic workflows for complex enterprise processes. • Worked on reinforcement learning and multi-agent systems for autonomous mission planning. • Designed AI evaluation frameworks for production GenAI systems. • Deployed AI solutions across GCP, AWS and Azure environments. Core technologies: Python | PyTorch | JAX | TensorFlow | LangGraph | LangChain | Google ADK | MCP | RAG | RLHF | PEFT/LoRA | Vertex AI | Gemini | AWS | GCP | Docker | FAISS | PGVector | Weaviate | XGBoost If you need more than a basic chatbot — whether that’s a reliable RAG system, an AI agent, an MCP integration or a production-ready GenAI platform — I can help design, build, evaluate and deploy it.
