Engineering Configuration & Automation
REX Builder - Rule-Based Engineering Configuration Platform
A web application that helps engineers build and check configurations using reusable rules.
Illustrative system view
Context
REX Builder helps technical teams prepare configurations with consistent options and rules.
Challenge
When options, rules and templates are managed separately, it is easy to miss an incomplete or conflicting choice.
Contribution
We worked on the web application, configuration rules, validation, review screens and export preparation.
- rule-based configuration
- guided input workflow
- data modelling
- validation states
- configuration summaries
- structured exports
- review evidence
- deployment preparation
Solution
The builder guides users through their choices, checks them against the rules and prepares an output they can review.
Builder workflow
Structured a guided workflow for selecting options, entering technical inputs, reviewing state, and preparing generated outputs.
Rule modelling
Modelled reusable rules, dependencies, and validation states so configuration behavior can be updated without scattering logic across the interface.
Validation and review
Added checks and review summaries that make incomplete, conflicting, or uncertain selections visible before export.
Structured outputs
Prepared generated outputs around traceable configuration data rather than manual copy-paste or one-off templates.
Application delivery
Worked on the application, its interface and deployment preparation.
How the system connects
- Reusable rule sets
- Guided configuration
- Validation states
- Review summaries
- Structured outputs
Engineering considerations
- configuration choices remain inspectable before outputs are generated
- invalid or incomplete combinations are surfaced instead of silently accepted
- rule sets are kept separate from presentation and export concerns
- confidential product details, rule libraries and templates are not published
Outcomes
- Created a clearer workflow for assembling engineering configurations from reusable rules and guided inputs.
- Made validation states and incomplete combinations visible before output generation.
- Established a maintainable base for reviewable configuration outputs and future rule expansion.
