Brainer

An Obsidian vault that holds the current state of every project. Each coding session starts by reading the project's handoff note and ends by updating it, so work picks up exactly where it stopped.

  • Handoff and status notes per project
  • Written workflows, such as the session handoff
  • Activity log and a dashboard built by a Python script

About

I design and build software on my own, from the first screen to the database behind it.

I'm Kimmo Meissner. msnr.studio is my independent studio. I work on both sides of a product: how it looks and feels, and the code, data model and deployment that make it run.

Most of what I build starts as a tool I need myself or one I build for people I work with. OFFSTG. is built for club teams who would otherwise plan events across spreadsheets, chats and paper. Brainer keeps my own projects organised.
