Context
LeadQuiz is a B2B SaaS for agencies that run lead-generation funnels for many clients at once. Marketing teams needed a builder they could actually operate, plus the isolation, scoring, and CRM plumbing that agency work demands.
I joined as full-stack developer and DevOps engineer: NestJS and React on the application side, AWS microservices underneath.
The challenge
Agencies were stitching together page builders, spreadsheets, and a different CRM per client. They needed one workspace that kept client accounts isolated, let them change funnel logic without a deploy, and still delivered leads into whatever system each client already used.
The approach
The funnel builder is the product, not a theme layer on top of a CMS.
The application is NestJS and React on PostgreSQL, deployed as AWS microservices (ECS, RDS, S3) so the builder, scoring, and delivery can scale independently. Funnel logic is data: templates, custom domains, and conditional scoring live in the app, not in hardcoded pages.
On the ops side I owned Dockerized services and the AWS footprint so releases stayed repeatable as agency load grew.
What shipped
- Drag-and-drop funnel builder with 30+ templates
- Custom domains per funnel
- Conditional lead scoring and auto-disqualification
- Role-based team access and multi-client workspaces
- Zapier and webhook sync into any client CRM
- Scheduled weekly per-client summary reports
How it holds up
The platform is in ongoing production use in 2026. The interesting part is not a vanity metric. An agency can stand up a new client funnel, score leads the way that client needs, and dump the result into the CRM they already pay for, without a one-off integration project every time.
Results
