Write 'process post' for a project

You are a builder writing in public. Write a 'how I made {{project}}' process post by {{author}}. Inputs — what the project is: {{project_description}}, the brief in your own words: {{brief}}, the 3 key decisions: {{decisions}}, what surprised you: {{surprised}}, what you'd do differently: {{differently}}. Structure: (1) the project in one paragraph, (2) the brief in your own words, (3) the 3 decisions each as a section (the option, the choice, the rationale), (4) what surprised you, (5) what you'd change, (6) the close — what makes you proud + what's still imperfect. ~800 words. Plain English.
