Before we work together

Can you take over our existing setup?

Yes. I review the configuration, source data, dependencies and integration ownership first. We agree the scope and test cases before changing business rules.

Do you handle architecture and implementation?

Yes. I work across HubSpot configuration, APIs, automation, HubL and front-end development. You work directly with me through planning, implementation and handover.

How do you approach AI customer agents?

I start with the knowledge sources, allowed actions and escalation rules. Testing includes unanswered questions, missing context and the handoff to a human.

What should I share to get started?

Send the business problem, the tools involved, what is already working and your target timeline. I can then outline the first step, required access and a practical scope.
