In this episode of the Elixir Mentor Podcast, we dive into JustCrossPost with creator Peter Solnica, exploring his journey from Ruby to Elixir development and the evolution of his social media automation tool. Peter shares insights on using AI for development, particularly for frontend work, and discusses how his background in functional programming through Ruby helped smooth his transition to Elixir. We explore the technical architecture behind JustCrossPost, including its use of Oban Pro workflows for reliable cross-platform posting, Cloudinary for image optimization, and his approach to testing both backend and frontend components. The conversation also covers the challenges of learning LiveView, maintaining multiple SDK clients at Sentry, and his thoughts on the impact of AI on software development, particularly for junior developers. Peter also teases upcoming features for JustCrossPost, including GitHub integration for open source maintainers and automated release announcements.
