Otter operates a unified restaurant platform processing millions of transactions across 100,000+ restaurants globally. The tech stack reflects a transaction-heavy, real-time business: Kafka + Apache Flink for streaming, PostgreSQL + Redis for state, plus integrations with payment processors (Stripe, Adyen, PayPal, Square) and POS vendors (Toast, Clover). Active projects around real-time data infrastructure, fraud detection, and streaming pipelines signal heavy investment in operational reliability and risk management—critical for a system handling high-volume transaction flow.
