• Develop and maintain APIs and backend services using Python, including RESTful APIs and microservice architectures.

• Develop prompt engineering strategies and evaluate LLM and agent responses using appropriate evaluation frameworks, metrics, and testing methods.

• Design and maintain document processing and data workflows, including PDF extraction, document transformation, structured output generation, and computer vision-based processing.

• Build and maintain knowledge bases and vector database implementations to support AI applications and retrieval workflows.

• Optimize AI and application architectures for performance, including reducing system latency and managing infrastructure and model costs.

• Implement secure authentication and authorization for APIs, services, and application integrations.

• Contribute to CI/CD pipelines, automated testing, monitoring, logging, deployment, and production support.

• Troubleshoot complex issues across AI applications, agents, APIs, integrations, data workflows, and supporting infrastructure.

• Work with cross-functional teams to understand business requirements, evaluate technical approaches, and deliver reliable AI-powered solutions.
