For Paris 2024, Visa returned to French advertising after 10+ years, putting window stickers in every shop that accepts the card. I built the platform that deployed and tracked the rollout across greater Paris, in real time.
What I did
One web app, three interfaces:
- Field app for 40 installers: daily routes, photo proof, merchant data.
- Ops back office: live tracking, installer performance, data QA.
- Live report for Visa: interactive map, per-shop photos, KPIs, shared in real time to update their CRM during the campaign.
I built the whole platform alone. Live in the field 2.5 weeks after winning the RFP.
Results
- 10,000+ shops equipped
- 18,000+ field photos
- 21,000+ visuals distributed
We won the contract with real-time tracking Visa had in no other market, which opened talks to deploy it in other countries.
Challenges
Thousands of independent shops with messy, inconsistent data, kept accurate in real time while dozens of installers worked across the city at once.
