- Glass Wall SRLAppSheet Expert & Data Architect | Construction ERP CreationCIVIL ENGINEERINGFebruary 2025 - Today (1 year and 5 months)Liège, Belgium
🎯 Business Challenge:
The company faced a highly fragmented and extremely time-consuming construction site management. Field monitoring of operational activities lacked fluidity, imposing a heavy burden of manual administrative work on management. The company also urgently needed to integrate a fully custom invoicing tool, as standard software providers were not customizable enough. Finally, a major technical and legal constraint was added: all invoices had to be routed through the secure European Peppol network.⚙️ Technical Architecture:
Centralization via AppSheet:Architectural design of a unified ERP system precisely covering the entire lifecycle of construction sites (measurement generation, order management, logistics tracking, and installation validation).Financial Automation (API):Creation of connected data flows natively integrating the European invoicing network Peppol, through precise technical synchronization between the AppSheet platform and the Falco management system.Cognitive Extraction (AI & OCR):Advanced integration of the OpenAI Artificial Intelligence API. The objective is to read, analyze, and extract key data from incoming invoices in a fully automated manner.Dashboards & Field Management:Deployment of an interactive financial dashboard and granular role management securing data access for various field users.📈 Impact and Return on Investment:
The development of this infrastructure resulted in complete operational fluidity in the field, coupled with structural cost savings and a measured reduction of 3 hours of daily administrative management for the leadership. - XGMAppSheet Engineer | Project ERP, Invoicing & HRCIVIL ENGINEERINGOctober 2025 - February 2026 (4 months)Liège, Belgium
🎯 Business Challenge:
The company suffered from administrative overhead that severely impacted the profitability of all its projects. The complex invoicing cycle and daily time tracking required too much manual data entry. Budget management became too time-consuming: project-based budgeting and the lack of expense tracking led to significant cost overruns. It was essential to structure a database linking each contract to a specific project, track team hours, and ensure Peppol compliance by connecting Falco to a custom AppSheet interface.⚙️ Technical Architecture:
Project Management Module:Creation of an interface centralizing all contracts and deliverables. Cross-tracking to compare initial quotes with actual expenses per project phase.Time Tracking Sheet:Time tracking system for employees to easily log their hours on the AppSheet mobile app. These hours are allocated to the project's cost of goods sold.Invoicing & Peppol Compliance:Automation of document generation (invoices, credit notes, quotes) and automated integration of flows onto the secure European network by connecting AppSheet with Falco and Peppol via API.📈 Impact and Return on Investment:
The synchronization of worked hours with invoicing immediately eliminated errors and accelerated payments. The AppSheet system massively reduced administrative work hours for the teams, freeing up valuable time for production. The company drastically reduced additional costs per project: thanks to rigorous structuring of quotes by phase and real-time expense tracking, budget leaks are finally plugged. Net margins optimized and legal compliance guaranteed. - Constantin caféAppSheet Developer | Restaurant & Food Cost ERPRESTAURANTS AND FOOD SERVICEDecember 2024 - October 2025 (10 months)Liège, Belgium

In a context of inflation, management struggled to maintain pricing agility. The establishment suffered from strong operational rigidity. With every fluctuation in supplier prices, the cost of goods for the entire menu had to be manually recalculated. The goal was to replace static spreadsheets with an interactive tool connected to purchasing, ensuring precise profitability, by creating a custom interface via the AppSheet platform.⚙️ Technical Architecture:
Interactive Glossary (Recipe Builder):Development of a technical sheet creation module dynamically linked to ingredient purchase prices, automatically recalculating production costs and gross margins for all dishes.Active Inventory:Raw material database with precise tracking of inventory levels and supplier price variations, preventing stockouts or shortages.Real-time Adjustment:Analysis interface allowing management to visualize the impact of a price increase on a global recipe, enabling near-instantaneous adjustment of selling prices on-site.📈 Impact and Return on Investment:

Instant visibility into profitability allowed for optimization of all margins in real-time, transforming menu operational management into a strategic tool. Continuous monitoring of perishable goods inventory led to a significant reduction in waste and shortages, considerably increasing the restaurant's overall net profit margin. This digital transformation allowed the manager to focus fully on their core business with data visualization tools.
