When to hire me

A good fit when an AI assistant needs context, tools and reliable handoffs.

This service is for businesses that need more than a generic chatbot: an agent with defined instructions, tool access, structured outputs, guardrails, escalation rules and a maintainable implementation.

Agent scope and behavior design

Define what the agent can do, what it must refuse, when it should ask follow-up questions and when it should hand work to a human.

Knowledge and retrieval setup

Connect service pages, documents, FAQs, product data or internal resources so responses use controlled business context.

Tool and API actions

Let the agent create summaries, classify leads, call APIs, prepare CRM payloads or trigger workflow steps with clear success states.

Testing and monitoring notes

Test real user scenarios, edge cases, hallucination risks, failure paths and ongoing prompt or data maintenance needs.

Process

FAQ

Quick answers before we start.

What is the difference between an AI agent and AI automation?

AI automation usually handles a defined workflow. An AI agent can interpret user intent, use context, call tools and decide the next step within controlled boundaries.

Can an AI agent use my website or documents as knowledge?

Yes. The agent can use curated service pages, FAQs, documents or product data as context, depending on the stack, privacy needs and update workflow.

Can you build an AI agent into an existing website?

Yes. I can add an agent as a web widget, internal dashboard, API workflow or lead qualification layer if the existing project can support the integration.
