Ten million push notifications a day

Context

Feedify lets site owners add browser push notifications without a developer. The engineering problem is delivery volume: notifications are bursty, third-party push endpoints fail unpredictably, and a slow consumer must not stall the rest.

Leadership & decisions

Queue-first. I directed the architecture around Kafka so that ingestion and delivery scale independently and a failing push endpoint degrades one partition rather than the platform.

SDK consistency as a product decision. Android and iOS SDKs were held to a shared interface standard so integration behaved the same everywhere — a support-cost decision as much as an engineering one.

Outcome

A platform reliably delivering more than ten million notifications a day, with cross-platform SDKs in production.
