Case study

A rules platform in eight days, its designer in one evening

A no-code platform that turns business decisions into automated workflows, built as a working product with its own marketing site.

The problem

Businesses bury their rules (pricing, eligibility, approvals) in spreadsheets and people's heads. Condexa lets non-developers design those rules visually and run them through an API.

How I approached it

  1. Twelve numbered specifications, each with a written plan and estimate before any code
  2. Parallel AI agents building in separate workspaces, with every change reviewed
  3. End-to-end tests run against a dedicated test workspace before each merge

What was built

  • Visual workflow designer with 11 step types and a wizard that turns a JSON sample into a workflow
  • Lookup tables reading live from SQL Server or Dataverse
  • Versioning, test runs with a trace of every step, and full run history
  • REST API with keys, workspaces, roles and a full security model

Stack

  • .NET 10
  • Angular
  • SQL Server
  • Dataverse
  • Docker
  • Azure
  • Next.js

Outcomes

  • A complete product, not a prototype
  • Marketing site built in a single day
  • Security model delivered in under a day
