I take AI prototypes and AWS applications to secure production: AI agents on Bedrock and Claude, ECS/EKS or serverless backends, Terraform, and CI/CD with proper approvals. I handle both architecture and hands-on build: APIs, data, security, testing, deployment, monitoring, and cost control. 9+ years of backend and cloud engineering.

Permissions, human approvals, retries, guardrails, evaluation and monitoring are built in from the start. RAG and Enterprise AI Search RAG systems that find the right information, answer accurately and cite sources. I improve retrieval quality, add access controls and test the AI's answers. Secure Production AWS Setup Containerized apps on ECS Fargate or EKS behind a load balancer, with private networking, KMS encryption, Secrets Manager, least-privilege IAM, logging, alarms and budget alerts. Everything is in Terraform or CDK so it can be recreated from code. No public databases or buckets, no wildcard permissions, and tested backup and restore. CI/CD and Release Safety GitHub Actions or other pipelines with OIDC: automatic deploys to staging, manual approval before production, and rollback runbooks. AWS Backend and Serverless Scalable APIs and event-driven systems with Lambda, API Gateway, DynamoDB, SQS, EventBridge and Step Functions. Architecture Reviews, Cost Optimization and Production Fixes I review your existing app and infrastructure, find the risks and cost leaks, fix production issues, and give you a clear plan. SELECTED RESULTS - Built event-driven services processing 5M+ orders per month - Cut cloud operating costs by 20% - Reduced manual AWS environment setup by 70% with reusable infrastructure code - Tripled application throughput while cutting infrastructure cost 30% through serverless and container migration TECH STACK AI: Amazon Bedrock, Claude, OpenAI, LangGraph, MCP, RAG, OpenSearch, pgvector AWS: ECS Fargate, EKS, Lambda, API Gateway, DynamoDB, SQS, EventBridge, Step Functions, RDS/Aurora, Cognito, KMS, Secrets Manager Backend: Python, TypeScript, Node.js, FastAPI, PostgreSQL, Redis DevOps: Terraform, AWS CDK, CloudFormation, Docker, Kubernetes, GitHub Actions HOW I WORK We agree on scope, priorities and acceptance criteria first. Then I build, test, deploy and document it, with a written handover so your team can run it without me. I'll also tell you when a simpler solution makes more sense. Not every problem needs an AI agent. Tell me what you're building, what already exists and what's blocking you. We can start with a focused review or go straight to implementation.
