Vertical slices, Solo, and empathy — product engineering with Aaron D. Francis

Aaron builds in public—Laravel roots, education, and now Solo, a terminal multiplexer–style desktop app for organizing agents and dev stacks. This episode is a practical tour of product sense for developers: watching people work, reading support email with empathy, cow paths vs. fences, and why the “right” architecture can still lose if humans go home furious.

You’ll hear how Aaron reasons from problem → solution when users ask for worktrees, when to duplicate UI affordances even when the model is “one,” and how introverts can still do discovery by treating outreach like an optimization mission—plus niche opportunities outside the Cursor clone gold rush.

• When someone asks for a solution (e.g. a feature), slow down and ask what problem they’re really trying to solve—users often lead with implementations.
• Practice user empathy: imagine someone stressed, trying to finish work; question “technically correct” UX that blames the user instead of protecting them (confirmations, back-button data loss, etc.).
• If talking to people is hard, reframe discovery as a systematic search (spreadsheet energy, trusted partners, or domain friends)—or pair with someone who loves conversations.
