THE CHALLENGE Revenue teams lose momentum when leads sit between a form submission, qualification, routing, and the next meaningful follow-up. THE SOLUTION Pipelin is a lead automation platform concept that captures, qualifies, and routes prospects without manual follow-up. It makes the flow of work visible from first signal to sales ownership. WHAT I BUILT • Visual lead-capture and routing workflow • Qualification rules with scoring thresholds • Automated welcome and nurture sequences • Real-time activity feed and pipeline analytics • Routing controls for market, company size, and priority • Responsive dark-mode SaaS dashboard DESIGN APPROACH A high-contrast operations interface uses deep navy, teal, and lime signals to make automation states, decisions, and performance easy to understand at a glance. THE OUTCOME A deployment-ready product demonstration combining workflow UX, data visualization, automation strategy, and frontend engineering.
