Sam, CTO of CustomD, presents a talk on encryption and data privacy in Laravel applications. He introduces their open-source library 'eloquent-model-encrypt' which implements hybrid encryption (combining symmetric and asymmetric encryption) to securely protect user data while maintaining granular access control. The library helps developers implement proper encryption practices without dealing with the complex cryptographic details directly.

Sam, a CTO at Custom D, discusses the evolution of deployment practices and how to achieve high DevOps maturity. He explains how organizations can move from monthly deployments with high failure rates to continuous deployment with minimal risk through incremental improvements, automation, and feature flags. The talk covers practical strategies for implementing modern deployment practices, including handling legacy code bases and getting organizational buy-in.
