Knipsr – From Product Build to Launch-Ready SaaS
A private, QR-based event media platform where guests upload photos and videos into a shared gallery with no app and no account — built to hold up under real event-day load.

What they came to us with, and what we shipped.
Before
A private event media product needs to feel effortless for a guest tapping a QR code — but every part of that simplicity depends on infrastructure that has to survive spotty mobile connections, large photo and video files, traffic that spikes hard during an event and disappears after, and edge cases a demo never surfaces. The risk isn't writing the upload form. It's what happens when an upload fails halfway, when storage has to hold years of event archives, or when a gallery has to stay fast at scale.
What We Built
We worked on the production engineering layer beneath Knipsr's guest and host experience: durable background job processing with retries and recovery for media uploads, storage and delivery architecture across Supabase, Postgres, Edge Functions, and Cloudflare Stream, caching and performance work on gallery loading, and access and expiry logic to keep private events private. Deployment ran across Vercel and Railway, with real-world QA and failure-mode testing before the platform carried live event traffic.
Built a no-login, QR-based guest upload flow for private event media
Implemented durable background processing with retry and recovery for large media archives
Tuned gallery loading and caching for real event-day traffic patterns
Hardened expiry and private-access flows to protect guest and host privacy
Stress-tested the platform against real-world failure modes before production use
Built With
"We could not be happier about working with Zumetrix Labs! What has started as an idea has turned into a really great projekt/product, which only evolved into its full potential through the corporation, ideas, experience, professionalism and openness from our developer. Everything was well understood, delivered on time and documented clearly. Thanks again. We can highly appreciate the work performed and couldn't recommend working with Zia and his Team enough!"
