Join Devhub Vancouver for their weekly series of Lunch&&Learns-- casual one-hour seminars with varying topics targeted at developers. Why not use your lunch break to learn something new?

This week's Lunch&&Learn topic is presented by Jossie Haines, Platform Engineering Director at Tile (

Jossie Haines will explain how we built a secure location finding network that supports 1.5 billion unique location updates per day. This is the world’s largest lost and found community spanning over 230 countries and territories and locating more than 3 million unique items every day.

In this talk, we will cover the whole stack from building a secure Bluetooth transport layer to developing a scalable backend service on AWS.
