About this gig

Need a fast, secure way to manage entry for your event, conference, or venue?


I'll build a custom QR code check-in system using Firebase the same kind 

of tech stack behind apps like Eventbrite's check-in tools.


WHAT YOU GET

Unique QR code generated per attendee or ticket

Real-time scan verification blocks duplicate or fake entries

Live dashboard showing who's checked in, as it happens

Scan with any phone camera no app download needed

Secure Firebase/Firestore backend no manual lists, no fake tickets


PERFECT FOR

Conferences weddings concerts school events gated venues workshops


WHY WORK WITH ME

I've built and deployed this exact system (SecureEntry) for a real event 

with 600+ live attendees and zero downtime so I'm not guessing. I know 

the edge cases: duplicate scans, offline handling, and fast lookups during 

busy entry rushes.


⭐ Real production experience, not just a template

⭐ Fast, clear communication

⭐ Tested under real event conditions

⭐ Support after delivery


Message me before ordering with your expected attendee count or any custom 

branding needs I'll tailor the right package for you.
