Electronic invoicing, automation, internal tools, and lightweight infrastructures deployed directly on the client’s server, without SaaS or external dependencies.

Design and deployment of autonomous technical systems built for real-world usage: document processing, business workflows, PDF generation, structured archiving, and backend automation.

Independent software publisher / integrator specialized in autonomous backend systems and electronic invoicing.

I build technical tools designed to run reliably in production environments, with a strong focus on simplicity, stability, maintainability, and data control.

I develop autonomous technical systems used in real-world environments: autonomous backend systems, autonomous electronic invoicing systems, automation, and internal tools.

Complete electronic invoicing system deployed directly on the client’s infrastructure:

• quote → signature → invoice → payment confirmation
• Factur-X / EN16931 compliant invoice generation
• PDF generation (client + server)
• structured archiving without database
• secure numbering and traceability
• automatic email sending
• bilingual FR / EN interface

Designed to replace invoicing SaaS platforms while keeping full control over data and infrastructure.

• internal tools and business workflows
• automation of recurring tasks and processing
• PDF generation and document processing
• document systems and structured archiving
• Stripe integration and secure processing
• database-free backend systems
• internal interfaces and batch processing
• autonomous server deployment without SaaS

Batch invoicing system based on Factur-X (EN16931):

• automatic generation from CSV
• structured invoice production
• full archiving and traceability
• secure delivery via token
• reproducible batch processing

Used to automate recurring invoicing workflows.

PDF Payment Stamping Engine
Tool for processing invoices in batch, integrated into Automation Finance workflows.

• ZIP import
• automatic PDF detection
• generation of stamped (paid) invoices
• individual or batch export

• quote generator (100% browser-based)
• factur-X electronic invoicing demonstration system
• static website foundations (HTML/CSS)
• local chatbots (Flask)
• documentation frameworks
• development environment configurations

Each deployment includes:

• server installation (shared hosting or VPS)
• full configuration (emails, paths, identity)
• adaptation to existing data
• testing and validation
• user documentation

Objective: a stable, autonomous and maintainable system.

• freelancers and independent professionals
• artisans and small businesses
• SMEs and operational teams
• businesses looking for autonomous systems without SaaS
• technical projects requiring simple, reliable, and maintainable tools

• autonomous systems, no SaaS
• minimal dependencies
• readable architecture
• predictable behavior
• long-term maintainability

The tools presented here prioritize clarity, stability and autonomy.
The goal is not to add complexity, but to remove it.

Systems favor local execution whenever possible
to reduce external dependencies and ensure portability.
