Engineering Deep Dive — Reddit's Python-to-Go Migration and Microservices Strategy

This module covers Reddit's most significant recent engineering initiative: migrating its comment backend from a legacy Python monolith to domain-specific Go microservices. The migration halved critical write latency and modernized Reddit's largest dataset. Candidates will learn the technical strategy, challenges, and lessons that reveal what Reddit values in engineers — pragmatism, careful migration planning, and the ability to work across complex distributed systems.
