// AI Agent Infrastructure — AWS Bedrock AgentCore

• Architected and deployed AI agent infrastructure using AWS Bedrock AgentCore — a managed platform for building, running, and operating autonomous AI agents (analogous to agent hosting on Azure AI Foundry and GCP Vertex AI Agent Builder).
• Provisioned and managed agent runtime environments (isolated, scalable sandboxes) that execute LLM-driven agent logic, handling concurrency, lifecycle, and resource isolation — equivalent to containerised agent execution platforms in cloud-agnostic terms.
• Integrated tool/API connectors into agent workflows enabling agents to invoke internal microservices, third-party APIs, and data pipelines as callable actions — following the Model Context Protocol (MCP) pattern used across the AI industry.
• Configured agent memory and knowledge stores using managed vector databases and session memory layers, enabling agents to retrieve contextual information across multi-turn interactions.
• Designed multi-agent orchestration topologies: supervisor agents delegating tasks to specialist sub-agents (search, data retrieval, summarisation), with tracing, retry logic, and guardrails at infrastructure level.
• Terraformed all AgentCore resources (agents, knowledge bases, action groups, aliases) as reusable modules enabling repeatable deployments across dev/staging/prod environments.
• Integrated AgentCore deployments into GitHub Actions CI/CD pipelines with blue/green promotion and automated smoke testing against agent endpoints.

// Cloud Platform & DevOps

• Terraformed the entire existing handmade AWS estate into structured IaC; authored shared Terraform modules eliminating infrastructure redundancy across teams.
• Architected and delivered migration of on-prem Docker Swarm to AWS ECS Fargate — covering design, ALB, CodePipeline, GitHub Actions integration, and multi-env rollout.
• Built centralised EventBridge solution to ingest Salesforce events and fan them out securely across multiple AWS accounts, with event filtering and schema transformation.
• Migrated CDN workloads from Akamai to CloudFront — led planning, architecture, and implementation phases.
• Set up IAM Identity Centre (AWS SSO) replacing per-account IAM users with access keys across the entire AWS organisation.
• Implemented AWS EKS clusters with ArgoCD for GitOps-driven application deployment; authored reusable ECS Fargate and EKS Terraform modules.
• Architected API Gateway solutions with integrated auth/authorisation; provisioned external IAM access for third-party integrations using External ID pattern.
• Deployed AWS Config rules with automated Lambda-based remediation; maintained Well-Architected review cadence.
