High-level expectations The repositories should include: Clean, senior-level Ruby code A practical app structure developers can learn from or reuse Email sending integrated via API or SMTP Environment-based configuration Clear README and setup instructions Basic examples of real-world usage Simple validation/testing instructions Clean GitHub-ready structure Ideal candidate You should have strong Ruby/Rails experience, understand transactional email workflows, and be comfortable creating developer-facing examples, starter templates, or open-source-style repositories.
