Camera and community album app for events, with ticket checkout and a fully AI-driven marketing agency. Guests take photos on their phones and contribute to the event's shared album — the host follows everything in a private, real-time gallery and can present the photos on a screen during the party. Solo project, from spec to deploy, including card checkout (Stripe) and Pix (AbacatePay).
Product and AI marketing agency running in parallel, not in sequence.
Guest scans an invite QR code, takes photos with a remaining-count tracker validated atomically in Postgres (prevents race conditions on double clicks) and contributes to the event's shared album. Host gets authentication, onboarding, event setup, unified checkout (Stripe for cards, AbacatePay for Pix), and a real-time photo presentation screen for the party. In parallel, the xis-agencia repository acts as the product's marketing department: 32 real Claude Code subagents, each with a single responsibility — trend research, competitor analysis, copywriting, image and video generation, landing page rendering — orchestrated by a central Skill, with every consequential decision logged in an evidence log for human review.
