A campaign platform that passed a multinational's security audit
A contest platform for a beverage multinational's internal campaign: rounds, practice area, study guide, AI assistant, bilingual emails, rankings and regional reporting. It passed the client's security audit and a load test with 500 simultaneous teams.
From problem to solution
- 01 · The challenge
A multinational's campaign is not won on the idea alone: it is won by getting past their IT department.
Any platform touching participant data has to survive a vulnerability audit before it goes live, and that is where most rushed builds fall over.
- 02 · What we did
We built the whole platform: team login with a captain, four rounds with a practice area and study guide, an AI assistant to answer questions, bilingual HTML emails in Spanish and English sent from the client's own domain, rankings, an admin panel and recurring reporting broken down by regional office. We built it knowing from day one it would be audited. The client's security team reviewed the platform, we fixed every finding before production and then ran a load test reproducing the worst moment of the event: 500 teams opening and playing a round at once. Over 43,000 operations, zero errors.
