Overview

Bulletproof digital infrastructure for Mercado Libre's official creators' awards — processing massive public voting and an exclusive VIP guest list without crashing under extreme traffic spikes.

Challenge

Mercado Libre needed a bulletproof platform to host their official creators' awards: seamlessly process massive public voting while managing an exclusive VIP guest list, all without buckling under extreme traffic spikes.

Objective

Map two distinct journeys — mass public voting and restricted VIP access — on AWS with LGPD compliance. Ship quick-registration with OTP for the public, a restricted RSVP flow with CPF validation and dynamic QR-code ticketing for 1,400 VIP attendees, and own end-to-end delivery including the automated WhatsApp and email comms layer.

Results

105,000 simultaneous users with zero downtime, delivered in under 6 weeks, 815,000 sessions and 40,000 validated votes.
