In this episode of Maintainable, Robby speaks with Joe Masilotti, an independent consultant who helps Rails teams ship mobile apps using Hotwire Native.

Joe shares his perspective on what makes software maintainable—especially for consultants who need to onboard quickly. He explains why setup scripts often add unnecessary complexity, and how he evaluates a project’s maintainability by how quickly he can go from clone to coding.

Robby and Joe also discuss how hybrid mobile development can offer faster delivery, fewer bugs, and better long-term flexibility—especially when teams reuse their existing Rails web views. Joe explains how Hotwire Native allows teams to incrementally introduce native features without rewriting their entire app.

Whether you’re maintaining a mobile shell built two years ago or just starting to explore native development, Joe offers actionable advice on setting expectations, scoping client work, and navigating modern mobile tech stacks.
