A redesign with complex specific requirements

M14Intelligence

Experts in emerging autonomous vehicle technologies, M14Intelligence was one of my first freelance projects. They wanted to redesign their old WordPress website while introducing new data processing tools.

From WordPress to Symfony: a whole new world

The need: moving away from WordPress for a more powerful solution
Our client's initial observation was clear: WordPress no longer met their requirements. The back office was deemed too complex for editors, and poor site performance had become a barrier to growth. They wanted a modern, fast, and bespoke solution.

A new ecosystem based on Symfony and Vue.js

We made a fresh start with the latest version of Symfony, integrating powerful tools like EasyAdmin for an intuitive back office and Vue.js for dynamic, responsive interfaces.
The result? A solid and flexible architecture, perfectly aligned with the client's needs.

Step 1: Data migration

The first challenge was migrating all data from the old site without compromising integrity. To achieve this, we exposed an API on the old WordPress site so the new site could consume data seamlessly. This method, designed for performance and reliability, ensured a smooth transition.

Step 2: A bespoke back office

We recreated all existing features while rethinking the user experience to meet the specific needs of editors. As a bonus, we added innovative tools, such as dynamic pop-ups highlighting market analysis directly linked to their publications.

Step 3: Reduced hosting costs

The switch to Symfony had a direct impact on resource optimisation. The site became lighter and faster, allowing the client to reduce the required server configuration. The result: significant savings on hosting without compromising performance.

A result that meets expectations

By leaving WordPress for a modern Symfony environment, our client gained performance, ease of use, and efficiency. This redesign marks a real turning point and paves the way for steady, sustainable growth.

Real-time data display

A key need: a secure, interactive dashboard
One of the primary goals of this project was to implement a data visualisation panel, accessible only to subscribed users. Here are the steps we took to meet this need:

Data processing workflow

The client used a large Excel file containing their analysis data, which was updated regularly.
To manage this complexity, we:

Designed an automated import process using a Python tool.
Processed the data line by line to create implicit links between entries.
Saved the processed data into a structured database, ready for use.

Data validation

Some data in the files was corrupted due to human error. To ensure reliability:

We established strict validation thresholds to detect and reject incorrect data.
These thresholds are configurable by the client, allowing them to adjust them as the market evolves.

Data visualisation

Once the data was imported and validated, the goal was to make it accessible via a modern, high-performance interface:

We developed a dedicated API to allow data consumption from the database.
Users can explore data across several visualisation axes, such as:
- Country
- Vehicle type
- Brand

Thanks to Vue.js and Chart.js, the interface is interactive, dynamic, and perfectly suited to user needs.

User subscription management

Access to the dashboard is restricted to subscribed users. To ensure this restriction:

We integrated a third-party subscription management service.
Each user is identified upon login, and their subscription is verified in real-time.
This connection with the third-party service also allows the client to obtain valuable data on subscriber profiles.

A dashboard that makes the difference

With this dashboard, our client has a powerful, modern tool to leverage their data in real-time while maintaining total control over subscriber-only access.

Automotive Big Data and system performance

The M14Intelligence project stood out for its ability to process massive volumes of data from the autonomous vehicle sector. The developed system manages millions of rows of complex data on sales and advanced technological components.

Sector-specific Big Data processing

The processed data included autonomous vehicle sales statistics and market analysis of critical components such as Lidar systems, sensors, and other emerging technologies. The volume represented several million rows from complex industrial reports, requiring a large-scale data processing approach.

Advanced filtering system

A sophisticated taxonomisation system was developed with approximately 30 different filters, allowing users to analyse data across multiple axes: vehicle type, onboard technology, geographic region, time period, manufacturer, etc. These filters dynamically generate visualisations such as trend lines, pie charts, and bar diagrams.

Stripe integration for subscriptions

Access to the premium dashboard is managed via a full Stripe integration, enabling automated user subscription management. This solution ensures robust access control while providing detailed analytics on subscriber profiles to optimise the commercial offering.

Performance and scalability

The optimised Symfony architecture allowed for a significant reduction in hosting costs compared to the previous WordPress solution, while efficiently handling the processing of millions of records. The caching system and query optimisation ensure fast response times even on large datasets.

Ce que ça a changé.

5x more visitors

The new website, optimised for SEO, led to greater prominence on search engines and an increase in the number of visitors. One year later, the site went from 40 daily visits to nearly 200 daily visits.

2x more conversions

The new design and interactivity offered on the site keep visitors engaged and improve the conversion rate from simple prospects to clients. M14Intelligence recorded double the conversions year-on-year.
