I will build an ai agent on aws bedrock with langgraph and rag


About this gig
I will build you a production AI agent on AWS Bedrock not a demo.
I'm an AWS Community Builder and DevOps engineer. I build agents that
run on real infrastructure, with cost control and guardrails.
What you get:
- AI agent with LangGraph orchestration (multi-step, tools, memory)
- Amazon Bedrock Knowledge Base (RAG) over your docs, PDFs, website or DB
- Bedrock Guardrails: no off-topic replies, no hallucinated answers, PII filtering
- Integration: WhatsApp, web widget, Slack or your own API
- Deployed on your AWS account (Lambda / ECS / API Gateway) with IaC you own everything
- Observability + token cost monitoring
Typical use cases: customer support, lead qualification, internal
document assistant, sales follow-up.
Tech: Bedrock (Claude, Nova), LangGraph, LangChain, OpenSearch
Serverless, Aurora pgvector, FastAPI, Terraform, Docker.
Message me before ordering with your use case and I'll tell you exactly
what's feasible and what it costs to run monthly.

FAQ
Do I need my own AWS account?
Recommended, so you own the infrastructure and pay AWS directly. I can also deploy in mine and hand it over.
How much does it cost to run?
Depends on volume. A typical support agent with a Knowledge Base runs USD 30–120/month on AWS. I'll estimate it before you order.
Can it hallucinate?
I use Bedrock Guardrails plus grounded RAG, so the agent answers from your documents or says it doesn't know.
Do I get the code?
Yes, full source and Terraform. No vendor lock-in with me.
Can it speak Spanish?
Yes, Bedrock models handle Spanish, Portuguese and English natively.
