**Travaux Tranquilles** is a custom-built web platform designed to transform how construction and renovation projects are managed. It addresses a critical need: **securing payments, organizing worksites, and restoring trust** between private clients and construction professionals.

## The Challenge

The construction industry suffers from a lack of transparency: clients worry about scams, contractors face payment defaults, and projects struggle with poor coordination between trades.

## Our Approach

Eskelia led the entire development with a strong requirement: **100% proprietary code, without CMS or turnkey solutions**. This approach ensures:

- **Complete intellectual property ownership** for the client
- **Total scalability** without dependency on third-party tools
- **Optimal performance** tailored to business needs
- **Enhanced security** for sensitive data and financial transactions

### Robust Technical Architecture

We designed a multi-stakeholder platform featuring:

- **Identity management**: Client, contractor, and site manager accounts with SIRET verification via INSEE API
- **Modular project system**: Breakdown into "blocks" by trade lots (plumbing, electrical, painting, etc.)
- **Smart escrow payment**: Funds are held and released progressively upon validation of each milestone
- **Material management**: Requests processed through a network of partner suppliers
- **Integrated communication**: Real-time messaging contextual to each project
- **Universal interface**: Responsive design optimized for all devices, including older generation phones

## Features That Make a Difference

### For Homeowners

- **Qualified contractor search** with verified profiles and transparent history
- **Total financial protection**: Your funds are secured until work is validated
- **Real-time tracking**: Project progress, budgets, schedules
- **Communication history**: All discussions centralized and accessible

### For Contractors

- **Payment guarantee**: Funds are provisioned before work begins
- **Optimized organization**: All your projects in one place
- **Simplified billing**: Automatic triggering upon each validation
- **Enhanced credibility** via official SIRET verification

### For Site Managers

- **Professional validation** of construction milestones (premium option)
- **Multi-project tracking**: Global management of multiple worksites
- **Valued expertise**: Compensated and recognized intervention

## Innovation at the Heart of the Trade

### Step-by-Step Escrow Payment

The "trusted third party" system ensures money is available but only released after work validation. Each trade lot has its own milestone system, allowing fine granularity and fairness for all.

### Automated Contractor Verification

Integration with INSEE API to validate SIRET numbers in real-time, drastically reducing fraud risks and strengthening client confidence.

### Structured Communication

Unlike scattered email or SMS exchanges, the integrated messaging automatically archives all project-related discussions, serving as evidence in case of disputes.

## Impact and Results

Travaux Tranquilles embodies a new way of approaching construction projects:

- **Trust restored** between clients and contractors through total transparency
- **Reduced disputes** through traceability of exchanges and validations
- **Industry professionalization** with modern and accessible tools
- **Financial security** for all stakeholders

## Modern Tech Stack

The platform relies on a proven architecture:

- **Frontend**: React for a smooth and responsive interface
- **Backend**: Node.js for optimal performance and robust request handling
- **Database**: PostgreSQL for reliability and integrity of critical data
- **Security**: Encryption of sensitive data, enhanced authentication, GDPR compliance
