A developer transformed a brittle Python script into a modular publishing platform in just three weeks. The original one-off tool was tightly coupled and couldn't handle multiple services. The new architecture separates concerns into distinct layers, making the system reliable and extensible.

The key change was implementing clear responsibilities. A pipeline layer orchestrates flow, while separate publisher and client layers handle platform-specific logic and API communication. A dedicated database layer tracks state and enables safe re-publishing. This separation prevents changes from breaking unrelated behavior.

Adding new platforms like LinkedIn or Substack is now straightforward, requiring only new client and publisher modules. The developer learned more about Python and system design in these weeks than in three years of casual coding. Future versions will add rate limiting and better observability.
