  • Mobile and backend architecture

Overview

Engineering notes from real projects

Every article here comes from work delivered for clients rather than generic commentary. The aim is to give founders and product teams enough detail to make better technical decisions before a build starts.

If you are planning a mobile or web product and want a second opinion on the approach, these are the patterns we would otherwise explain in a first call.

How these guides are written

  • Step-by-step commands you can actually run
  • Architecture decisions with the trade-offs spelled out
  • Checklists drawn from shipped releases
  • No invented metrics or copy-paste tutorials
