  • Build backend services, APIs, integrations, authentication, workflow logic, and lightweight user interfaces.
  • Design data ingestion, transformation, retrieval, and knowledge-integration pipelines across enterprise systems, databases, documents, APIs, and search or vector services.
  • Develop secure and scalable backend services and relational data models using technologies such as Python, FastAPI, and PostgreSQL.
  • Define evaluation datasets and acceptance criteria, test quality and reliability, and implement tracing, monitoring, and continuous improvement.
