ECO-MED Application Hub
#

Design and development of a complete application ecosystem to digitize and optimize business processes for ECO-MED, a consulting firm specialized in environmental expertise.

🌍 Context
#

12-week internship (April - June 2024) within the R&D department of ECO-MED, an SME with 100 employees specialized in ecological engineering. Mission: support the company’s digital transformation by developing business tools adapted to the specific needs of ecologists and project managers.

🎯 Project Objectives
#

Centralize access to various business tools through a single entry point
Automate time-consuming tasks (report generation, data extraction…)
Optimize internal processes (carpooling, field planning…)
Ensure reliability of environmental data collected in the field
Facilitate adoption of digital tools by teams

🚀 Developed Applications
#

1. Central Application Hub
#

Single entry point to all business tools:

Responsive and intuitive web interface
Simplified navigation between different applications
Integrated FAQ section for user support
Contact form for feedback and suggestions

2. ECO-carpooling
#

Field trip optimization application:

Map visualization of planned routes
Intelligent grouping of participants by zone
Integration with ERP to retrieve schedules
Filters by month, profile, and participant

3. GOAT (Generator of Atmospheric Observations in Tables)
#

Automatic weather table generation tool:

Intuitive selection of study areas on interactive map
Weather data retrieval via Open-Meteo API
Export of formatted tables for study reports
Data: temperature, wind, precipitation, humidity

4. FroggyFactors
#

Decision support application for amphibian inventories:

Precipitation analysis over customizable period
Interactive charts of rainfall data
Comparison with historical data (5 years)
Identification of optimal intervention periods

5. FeuForêt (FireForest)
#

Fire risk visualization module:

Interactive map of French departments
Real-time integration of prefectural data
Legend adapted to ECO-MED’s specific needs
Quick access to critical information

🛠 Technical Architecture
#

Technology Stack
#

Frontend: Vanilla JavaScript, HTML5, CSS3
Backend: Node.js, Express.js
Database: MongoDB
Mapping: Leaflet.js
Charts: Chart.js
APIs: Microsoft Graph, Open-Meteo
Infrastructure: Dedicated Linux Debian server

Architecture Choices
#

Classic client-server architecture
REST API for communication
Modular and scalable approach
Compliance with SOLID principles
Security according to OWASP recommendations

🔧 Technical Challenges Overcome
#

1. Interfacing with existing ERP
#

Problem: No business API to retrieve schedules
Solution: Using Microsoft Graph API to extract data from Excel export emails
Result: Complete process automation without manual intervention

2. Data Quality Management
#

Problem: Duplicates and incorrect data in exports
Solution: Intelligent deduplication algorithm based on hashes
Result: 100% reliability of processed data

3. Performance and Scalability
#

Problem: Slowdowns during load increase
Solution: MongoDB query optimization with indexing
Result: Response time divided by 5

📊 Results and Impact
#

Quantitative Gains
#

⏱️ 80% reduction in weather report generation time

💻 Technical Implementation
#

The ECO-carpooling application uses a specially developed REST API to retrieve and format field planning data. This API aggregates information from different sources (schedules, geolocation, user profiles) and structures it for map display. The system handles field data retrieval with geographic coordinates, associated participant information, and planning metadata, while ensuring robust error handling and appropriate date formatting for the French user interface.

💡 Innovation and Added Value
#

This project illustrates how digitalization can transform environmental professions. By automating repetitive tasks and facilitating access to information, the developed tools allow ecologists to focus on their core business: biodiversity protection.

“This internship allowed me to put my technical skills at the service of a cause close to my heart: environmental preservation. Seeing the concrete impact of my work on the teams’ daily life was extremely rewarding.” - Léon Fievet
