Tell Us About Your Project [Amazon Web Services](https://aws.amazon.com/partners/) ## Amazon Web Services AWS Partner Network memberBedrock and AgentCore in production Most of what we ship runs on AWS: Bedrock for models, AgentCore for hosting agents, Lambda and ECS for services, and pgvector on RDS for retrieval.

GPT-4.1 handles reasoning in a production voice assistant, and GPT-4 writes the lesson scripts in a content pipeline that has produced more than 200 course modules. The API keys and the bill sit in your own OpenAI account, and model calls go through your own code, so the provider can change later. Shipped with it - [Voice assistant for Medicare patients, on GPT-4.1](https://vindler.solutions/case-studies/medicare-voice-assistant) - [E-learning content generation on GPT-4](https://vindler.solutions/case-studies/elearning-content-generation) - [OpenAI's Decisions API for agent routing](https://vindler.solutions/blog/openai-decisions-api-agent-routing) Hire for it [AI engineers](https://vindler.solutions/hire/ai-engineers) [LangChain and LangGraph](https://www.langchain.com/) ## LangChain and LangGraph Open-source contributorLangGraph multi-agent systems in production LangGraph is our default for stateful agents that pause for human approval, call real backend services and need to be observable.

No. We pick the platform per project and write down why. Model calls go through a thin layer of your own code, so switching from one provider to another is a configuration change plus an evaluation run, not a rewrite. ### Do you resell any of these platforms or take referral fees? We do not resell licences or cloud usage. You pay AWS, Langfuse or any other vendor directly, on your own account. If a vendor ever paid us for a referral on your project, we would tell you before you signed. ### Whose accounts do you build in? Yours, from day one. The repository, cloud account, model API keys and observability project are created in your company's name, and we work in them with access you can revoke. ### We already ran a pilot that stalled. Can you pick it up? Usually, yes. We start with a fixed-price review of what exists, so you know what is worth keeping before anyone commits to a build.
