Qubio Ecosystem

QR/NFC digital identity pages you edit from phone or web.

18-month engagement on a cross-platform identity system: React Native for scan/register and page editing, web admin for management, and a D3 analytics view of how the network is used — shared API for an international client deployment.

The Problem

An international client needed digital identity that lived on QR and NFC touchpoints — pages people could open from a tap or scan — plus admin tools and analytics so the network’s usage wasn’t a black box.

What I Built

Qubio is a cross-platform identity system I worked on across an 18-month engagement with a distributed remote team:

  • React Native for scanning/registering identities and editing page content on the phone.
  • Web admin for managing pages and the identity network.
  • Analytics dashboard (D3) for scan/tap visibility across the network.
  • Shared backend so mobile and web read the same source of truth.

Product surface: pages.qubio.me.

Major Features

  • QR / NFC identity pages — open, share, and present a digital presence from a physical tag.
  • In-app page editing — add blocks / update content without a separate CMS dance.
  • Web management — desktop admin for the same identity graph.
  • Usage analytics — dashboard views of how the network is actually used.
  • Long-running delivery — sustained feature work across time zones for an international deploy.

Key Challenges

Treating the API as a contract mattered: mobile and web couldn’t break each other mid-sprint over 18 months. Analytics had to stay responsive as usage grew — push aggregation down rather than chart raw dumps client-side.

Results

The system shipped and ran in the client’s international operation across the engagement window.

Stack Decisions

Native mobile for field scan/edit, web for admin density, D3 for custom analytics control. A shared API kept identity data from forking into two products.
