Working Demos

See the decision before the build

These are proof-of-concepts we use to validate options so we choose the right approach with evidence, not guesswork. Demos are a tool when helpful, not a requirement for every project.

How demos fit into the work

Most advice is theoretical: “We should use X because…”

I make it empirical: “We built the options — here’s cost, performance, complexity, and risk.”

  • Validate build vs buy before you spend real budget
  • Compare stacks with live behaviour — not slides
  • Surface hidden costs (ops, compliance, hiring, maintenance)
  • Decide faster with less rework and technical debt

Use cases: new product bets, rebuilds after failed projects, or critical architecture choices. If a demo won’t change the decision, we skip it and move straight to delivery.

Timeboxed Decision Support

3–5 day window

When required before build Discuss Your Decision
Will you build a demo for my project?
Only if it reduces risk or clarifies a choice. If the decision is already clear, we go straight to a timeboxed build.
Do these demos become my product?
They’re decision tools. If we proceed, we build the production version with the right architecture, tests, and docs — and you own everything.
