KEY CONTRIBUTIONS
Architecture & product vision
Designed and built 3 independent, interconnected applications: a public landing page, the main app and a REST API — a scalable architecture planned from day one to support platform growth.
Customizable landing page builder
Built an integrated tool so each organizer can create and publish their event website in minutes, without WordPress or an external vendor.
Multi-client email builder
Created an in-platform email editor, removing reliance on third-party tools like Brevo — compatible with major mail clients for consistent rendering.
Ticketing with mobile QR check-in
End-to-end paid ticketing: Stancer for secure payments, QR generation, scan from any phone — real-time validation with no external infrastructure.
SaaS monetization
Recurring subscriptions via Stancer (plans, webhooks, access control) so organizers can subscribe directly on the platform.
Dynamic SEO
Automatic URL and metadata generation per event, making every page indexable without manual work.
IMPACT
Create an event (in-person, online or hybrid) in under 5 minutes, vs. 2–3 days of training on tools like Eventbrite
Full event stack in one place: ticketing, dedicated website, email comms and check-in — no Brevo, no WordPress, no external scanners
Mobile QR check-in: staff scan directly from their phone connected to Eloyse, zero third-party hardware to rent
Unlimited events, all formats supported (in-person, online, hybrid)
