  • Build AI solutions using LLM orchestration frameworks such as LangChain, LlamaIndex, or similar frameworks.
  • Design and optimise prompts using advanced prompt engineering techniques, including zero-shot, few-shot, Chain-of-Thought (CoT), and function calling.
  • Build Retrieval-Augmented Generation (RAG) solutions using vector databases such as Pinecone, ChromaDB, FAISS, or Weaviate.
  • Integrate AI applications with cloud AI platforms, including AWS Bedrock, Amazon SageMaker, Azure OpenAI, and Google Vertex AI.
  • Apply NLP concepts, embeddings, and transformer models to solve business problems.
  • Collaborate with cross-functional teams to deliver scalable, production-ready AI solutions.
  • Follow software engineering best practices, including version control using Git, CI/CD pipelines, and technical documentation.
