Enforce Process and Inspect Your Process

In this episode, Jeff and Luca tackle the unique challenges faced by solo embedded developers. Drawing from their own experiences as consultants, they explore why working alone makes it harder to maintain good development practices - from the constant pressure to multitask across different stakeholder demands, to the difficulty of wearing multiple hats as leader, manager, and contributor simultaneously.

The conversation moves through common pitfalls: skipping documentation because "it's all in my head," letting code reviews slide, making questionable architecture decisions without a sounding board, and neglecting tools like simulators under time pressure.

But this isn't just a catalog of problems - Jeff and Luca share practical strategies for staying disciplined, from creating mastermind groups with fellow solo developers to strategically hiring third-party reviewers for architecture decisions. They discuss how to push back on arbitrary deadlines, the value of enforcing process on yourself, and why sometimes the best productivity hack is spending money on training to force yourself to sharpen your skills.

Whether you're a solo consultant, the only developer at a startup, or part of a small team, this episode offers honest insights into maintaining quality and sanity when you're working largely on your own.

Notable Quotes

"When you're a solo developer, you have to be the leader, the manager, and the contributor for the software effort. Those are different roles and different skills." — Jeff

"You must apply agility to agility. Inspect your process, figure out what works, what doesn't work. If something is annoying to you, either it's pointing you towards a real deficiency or it's just objectively a terrible process and you should change it." — Luca

"It's really scary how effective rubber duck debugging is. You start to think of what the other person would answer, even though you're just talking to a rubber duck." — Jeff

"Simple and easy are not the same things. Having good development practices, just like losing weight, is simple. It's just not easy." — Jeff

"Dear listeners, have you ever paid with your own money for software development? Because I have. And it's really unnerving. You tell this developer to go do something and they just sort of disappear and you can hear the meter running." — Luca
