The problem
A UK marketing group ran dozens of campaigns with separate tooling for pages, CRM and dialing, and had no unified validation or attribution.
What I built
- 01
Campaign-aware CRM and landing page builder with hundreds of SSR funnel pages.
- 02
Call center across email, SMS, calls and WhatsApp via Twilio and gateways.
- 03
Lead validation pipeline with AML and credit APIs (Experian, Equifax UK).
- 04
Redis caching and query tuning that cut API latency by about 40%.
Outcome
£100M+ revenue generated across campaigns.
2M+ leads processed daily.
