Guided VIN generation
Turned a rule-heavy process into a clear sequence that helps users enter trailer information and understand the resulting VIN.

VIN Generator
A working application that turns trailer data into a structured VIN workflow with validation, searchable records, and production-ready output.
The challenge
VIN generation combines strict data rules with practical production needs. The application had to make complex inputs understandable, prevent invalid combinations, preserve records, and produce information people could actually use.
My approach
I translated the rules into guided inputs and immediate validation, then built the surrounding record workflow so a generated VIN is not a disposable result—it remains searchable, understandable, and connected to its source data.
Before
Users had to understand specialized VIN rules, repeat trailer information, and manually catch incompatible or incomplete values.
Automation
The application guides entry, applies validation as data is entered, generates the VIN workflow, and preserves each submission as a usable record.
Operational result
The process is easier to complete consistently, invalid inputs are stopped earlier, and prior work remains searchable instead of disappearing into one-off calculations.
What I built
Turning the workflow into a usable product.
Validation at the point of entry
Added constraints and feedback where errors happen, reducing the chance that incomplete or incompatible data reaches the final record.
Persistent, usable results
Connected generated values to saved records and production-ready output so the tool supports repeat work instead of ending at a single calculation.
Key decisions
Clarity before complexity.
Explain the rules through the interface
The product guides users toward valid data rather than expecting them to memorize every underlying constraint.
Treat every result as a record
Saved history keeps the final VIN connected to the information that produced it and makes previous work easy to reference.
Engineering the solution
What makes the product dependable.
- React interface for guided batch creation
- Rule-based validation at the point of entry
- Persistent records and searchable production history
- Role-aware workflow states and production-ready output
- Live deployment at vin.codyjohnson.dev
