A comprehensive guide to designing, building, and integrating a scalable notification infrastructure for modern financial services platforms
In organizations operating multiple digital products, notifications are often treated as local features. Each application manages its own emails, SMS, or push notifications, with its own rules, templates, and provider integrations.
As systems grow, this fragmentation quickly turns into an architectural issue: inconsistent user experience, operational complexity, compliance risks, and increasing technical debt.
In a long-form technical article, François Bossière, co-CEO of Polynom, presents a unified notification system architecture, designed as a transversal platform capability. While the reference example is a banking platform, the principles described apply broadly to SaaS products, marketplaces, B2B platforms, and regulated environments.
The article is primarily intended for CTOs, architects, and senior engineers, and focuses on conceptual models, architectural principles, and structural design choices required to scale notification systems.
