A full product walkthrough of Three-Pulse, a multi-channel customer-engagement platform I designed and built end-to-end. Using a sample energy retailer (Helios Energy), the video runs a real campaign across email, SMS, voice, and interactive Beam pages — all from one prepaid balance, one shared contact list, and one analytics view.
Built solo: Next.js + TypeScript (Vercel) frontend, Python/FastAPI (Fly.io) backend, PostgreSQL. Highlights: per-channel AI content drafting, Stripe multi-currency billing, an interactive page builder with 50+ block types, white-label custom domains, TOTP MFA, and PCI-aligned security. Live in production, bilingual EN/PT.
One honesty note: I framed Helios as a "sample" retailer, not a real client — keep that word in. On a hire-me profile, implying Helios is a paying customer is the kind of thing that unravels in a discovery call. "Sample/demo scenario showcasing the platform" is both true and still impressive.
