In this episode, we share our own experiences of what it’s like to code in isolation — and why it held us back more than we realised at the time. When you're working solo, it’s easy to miss out on learning opportunities, fall into unhelpful habits, or lose momentum altogether. But when you start coding alongside others, everything shifts. We talk about how code reviews gave us instant feedback, how collaborating with other devs helped us level up faster, and how the simple act of being part o...
