The challenge

What the client was facing

The goal of the project was to build a platform and public API that combine a simple VIN form, a clear report, and a smooth checkout into a single funnel — while maintaining performance even under heavy traffic.

Approach

What we did structurally

Clear VIN entry point

The homepage was designed around a single goal: quickly starting vehicle verification by VIN number.

Modular Report 2.0 structure

The report is divided into logical sections with a contextual menu, making it easy to navigate large amounts of data and quickly find key information.

Recommendations and warnings layer

Suggestion mechanisms and damage interpretation were implemented to help users assess the risk of purchasing a vehicle.

Process

How did the delivery process look?

User journey design

We mapped the full flow from the VIN form to payment, defining critical decision moments and points requiring maximum clarity.

External system handling

We designed the report structure based on sections generated from data analysis across multiple sources.

Optimisation

We optimised the API and AWS infrastructure so report delivery time is minimal even under heavy load — with no compromise on data quality.

Project context

About the project

HistoriaSzkod.pl is a SaaS platform and public API for verifying vehicle damage history by VIN number. The user enters a number, receives a comprehensive report — with a damage timeline, warnings, legal status, valuation, and photo gallery — and finalises the purchase in one seamless process.

The project was carried out in collaboration with Datazen . The key challenge was connecting three stages — VIN verification, report analysis, purchase — into a single journey, while maintaining API performance handling hundreds of concurrent requests from multiple external data sources.

How we solved the performance problem

We built the backend on Node.js with AWS infrastructure and Docker containerisation. The API queries multiple external data sources simultaneously and returns a complete report within seconds — regardless of load. We implemented monitoring of critical system nodes, giving the client full visibility into performance, data quality, and business metrics.

Report 2.0 was divided into logical sections with a contextual menu — damage, timeline, warnings, legal status, valuation, gallery. The checkout is decision-oriented — report benefits and payment conditions on a single screen.

The platform is the foundation for the Historia Szkód browser plugin , which detects VIN numbers on listing pages and enables instant verification with a single click.
