Data Management With Ruby — Sergey Sergyenko at wroclove.rb 2022

Sergey Sergyenko argues Ruby is well-suited for data management roles (not just data engineering) and walks through a HIPAA-compliant healthcare project where inherited PII led the team to build Grazer, a Faker-powered data obfuscation tool that masks production data while preserving shape, relationships, and consistency.
