- Proficiency in backend frameworks such as FastAPI, Django, or Flask, including building RESTful APIs and microservices.

- Experience with vector databases such as Pinecone, FAISS, or Weaviate, and familiarity with embedding techniques.

- Solid understanding of prompt engineering, retrieval-augmented generation (RAG), and natural language processing workflows.

- Experience with containerization and orchestration tools such as Docker and Kubernetes (preferred).
