  **Progressive Web Apps (PWAs): A stepping stone towards a native mobile application**  
  Progressive Web Apps (PWAs) are now a viable option for providing a mobile experience that meets users’ high expectations. This article provides an introduction to the history of PWAs for those new to the topic, as well as what can be expected from them in 2024. We also look at where PWAs sit in the mobile landscape and how they can be a practical stepping stone towards a native application experience in the future.

  **What we learned applying the Thinkmill Method to a complex accounting app**  
  We recently wrapped up delivery of a feature for a client’s complex accounting app. The project presented a valuable opportunity to battle-test our thinking around how we build products. We implemented a range of activities and techniques from the Thinkmill Method, and came away with valuable insights related to where it shines, what’s needed in order for it to do so, and how to improve it going forward. Here‘s what we learned along the way.

  AI-assisted development genuinely accelerated engineering teams, but many organisations stopped at the velocity gains and ignored the accumulating debt. The costs: code nobody fully understands, weakened code review culture, bloated dependency trees, and architectural decisions made without real judgement about tradeoffs...
