EventFlow Pro
End-to-end event ticketing & check-in platform
An events company was running ticketing, email, check-in and analytics across six-plus disconnected tools, with a clunky registration flow and paper check-in queues. We built EventFlow Pro — one platform from ticket sale to post-event analytics — engineered to stay up when a popular release sends thousands of buyers at once.
Six tools held together by hope
The team was piecing every event together from six-plus separate tools for ticketing, email, check-in and analytics, with manual hand-offs between each one.
I looked at where attendees dropped off and where staff lost time. Two answers stood out: registration was clunky, and check-in was still paper-based.
- Walked the full event flow from on-sale to post-event analytics
- Measured drop-off in the registration funnel
- Found the hand-offs between tools were where things broke
A leaky funnel and a fragile system
Two kinds of pain stacked up: lost revenue at the top of the funnel, and a system that buckled exactly when it mattered most.
- A clunky registration flow with a ~40% abandonment rate
- Paper check-in causing long queues and frustrated attendees
- No unified view of attendee behaviour or event performance
- System crashes during high-demand ticket releases
- No way for attendees to connect before or during events
Surviving the viral on-sale
The signature risk of ticketing is the spike — thousands of people hitting “buy” the second a popular event opens. That moment is where the old setup crashed.
I built for the spike from day one: serverless functions that auto-scale, a queue for high-demand releases, database connection pooling, rate limiting and CDN caching — so a peak on-sale becomes a non-event.
From cart to a 3-second check-in
The attendee experience had to feel effortless on a phone, from buying a ticket to walking through the door.
- Mobile-first checkout that strips friction out of buying
- QR tickets delivered by email and SMS with wallet support
- Contactless QR check-in in seconds, with an offline mode for unreliable venue WiFi
- Built-in attendee networking plus automated email/SMS campaigns
One platform, end to end
Next.js + TypeScript with PostgreSQL, Stripe across 135+ currencies, SendGrid, Twilio and WebSockets, deployed on Vercel’s edge network.
The client went from juggling six tools to running everything in one place — and the platform held steady through the high-traffic on-sales that used to take the old setup down.
