AI Infra Architecture

Design and implement scalable AWS infrastructure to support Generative AI and LLM workloads, including training, fine-tuning, and inference.

Architect secure, high-performance environments using AWS core services such as Amazon SageMaker, Amazon Bedrock, Amazon EKS, AWS Lambda, and related cloud-native components.

Design GPU-based compute environments (e.g., EC2 P-series, G-series) optimized for distributed training, fine-tuning, and low-latency inference.

Implement secure VPC architectures, private endpoints, IAM policies, encryption (KMS), and enterprise-grade data governance controls.

Build and govern MLOps/LLMOps pipelines using SageMaker Pipelines, CodePipeline, and CI/CD best practices.

Architect RAG infrastructure, including vector databases (OpenSearch, Aurora PostgreSQL with pgvector) and scalable storage solutions (S3).

Establish monitoring and observability using CloudWatch, model monitoring tools, logging frameworks, and performance dashboards.

Optimize infrastructure for latency, autoscaling, high availability, and cost efficiency, leveraging Spot Instances, Savings Plans, and right-sizing strategies.

Define disaster recovery (DR) and backup strategies across multi-AZ and multi-region AWS setups.

Implement Infrastructure as Code (IaC) using Terraform or CloudFormation for consistent, repeatable provisioning of AI environments.

Collaborate with AI/ML teams to support LLM fine-tuning, prompt orchestration, inference endpoints, and model deployment workflows.

Stay current with AWS GenAI advancements, evaluating new services, architectural patterns, and best practices for enterprise adoption.
