Summary from the TLDR Dev newsletter

Monday.com addressed its monolithic Rails notification system, which was hard to extend and suffered from rate-limiting losses, by migrating it to a TypeScript microservice with a simple JSON and SDK interface. This new system uses a three-stage SQS flow (process, filter, and deliver) to manage 8M+ daily notifications across platforms like email, mobile, and Slack.
