Boletapp
Anti-fraud ticketing for nightlife and concerts in Colombia.
Overview
Boletapp is an end-to-end ticketing and access-control platform for nightlife and large events: white-label sales pages, checkout with local payment methods, door scanning, and an operations dashboard. It targets the industry's revenue leak — tickets forwarded over WhatsApp that get scanned twice, untraceable promoter commissions, and unpaid table reservations — with cryptographically verifiable tickets and automated payouts. Built and in testing; not launched yet.
Highlights
- • Rotating anti-fraud QR: HMAC-derived codes that rotate constantly, so a forwarded screenshot is worthless — the same crypto engine runs in TypeScript and Python with shared test vectors enforcing bit-for-bit parity
- • Offline-first door scanner: validates from any phone's browser with no connectivity and across multiple doors at once, reconciling later with single-use guarantees
- • AI-powered bookkeeping: a receipt photo or PDF becomes a ledger entry via local Spanish OCR plus LLM structuring; cloud and SMS costs import themselves via BigQuery
- • Organizer dashboard: sales, capacity and promoter commissions in real time, an interactive table/floor-plan editor, plus calendar and map views of events
Architecture
- • Server-rendered web app with a BFF layer, per-organizer white-labeling and a PWA scanner; cross-platform mobile app sharing the crypto engine and domain types through a monorepo
- • Modular Python monolith organized by domain (identity, catalog, sales, payments, tickets, access control, finance), multi-tenant with database-level isolation and KMS-managed per-event keys
- • Two-stage receipt pipeline (local OCR → LLM structuring), automated cost ingestion from the data warehouse, and a reporting layer with spreadsheet exports
