Architecting Your Customer Notification Strategy w/ Sandor Nyako | LinkedIn Engineering

Architecting Your Customer Notification Strategy w/ Sandor Nyako | LinkedIn Engineering

Aug 4, 2021

In the past, each LinkedIn application team decided their notification strategy in isolation. Business logic and infrastructure sharing were limited between the teams. This resulted in a fragmented and inconsistent tech stack across LinkedIn and a less than savory member notification experience.

To combat this disjointed experience, Linkedin set up a small team to build an orchestration layer, the Air-Traffic Controller (ATC). This became one of the more complex notification systems and helped Linkedin grow into the top social platform for business and networking.

We have invited Sandor Nyako, Director of Software Engineering at Linkedin, to discuss what it was like scaling out from owning the ATC system to build the Comms Platform organization, and what recommendations he has for teams thinking about the future of this new form of user experience.
