SYSTEM ARCHITECTURE

The pain

The agency had an existing AI outreach system that worked, but it only handled one campaign type. They needed to scale to 120 distinct monthly campaigns, each pulling from different Salesforce candidate pools with different job specs and outreach copy.

Rebuilding from scratch was wasteful. Extending the existing system was the right play.

The team needed someone to architect the parallel system, integrate with their live tools, and not break what was already working.
