• Integrate Python applications with AWS services including Lambda, S3, API Gateway, ECS, EKS, EC2, DynamoDB, RDS, SQS, SNS, CloudWatch, and IAM.
• Develop AI-powered applications using LLMs such as GPT and Cohere.
• Build and optimize prompt workflows, embeddings, semantic search, and Retrieval-Augmented Generation (RAG) solutions.
• Implement document-processing pipelines using chunking, segmentation, tokenization, and metadata enrichment techniques.
• Design and optimize different document chunking strategies, including fixed-size, recursive, semantic, and context-aware chunking, based on data type and use case.
• Develop and maintain RESTful APIs and event-driven microservices.
• Design scalable and reliable backend services using microservices architecture.
• Package and deploy applications using Docker and container orchestration platforms such as ECS/EKS where applicable.
• Develop and maintain CI/CD pipelines for automated testing, deployment, and release management.
• Monitor application performance and troubleshoot production issues to improve reliability, scalability, and performance.
• Follow secure coding practices and AWS best practices for IAM, access control, logging, monitoring, and application security.
• Write and maintain unit, integration, and end-to-end tests.
