"Still shipping code — because architecture decisions age badly when you stop."

I lead engineering teams, and I keep writing code, exploring new architectures and hacking on side projects. Staying hands-on is what keeps my technical judgement honest. This profile is my digital playground.

• Scope: Leading up to 95 engineers (Managers, Architects, Devs, QA) on 6 different Supply Chain Solutions at QAD
• Focus: Merging technological excellence with a pragmatic business vision to transform innovation into a sustainable competitive advantage for our customers (in line with end users’ expectations) and for the efficiency and well-being of our teams.
• Recent wins: Transform legacy Supply Chain Planning Solution (DSCP) from On Premise to real SaaS

Here are some of my public experiments and labs that I like to maintain:

• ZeTimeConnect - A basic script and GUI to reconnect and interact with the MyKronoz ZeTime hybrid watch. (Python)
• GoogleAgendaAssistant - Import .ics files and iCalendar feeds into Google Calendar: a serverless browser app, plus a Flask variant that also syncs a SIGA university timetable. (Python, JavaScript)
• Fibonacci - Caching strategies and algorithmic optimization compared across three stacks: Python (Flet GUI, pytest), a .NET 9 API with a Vue 3 front end, and Java 21 with Spring Boot. (Python, C#, Vue, Java)
• FruitSudoku - A fun Sudoku game using fruits and vegetables instead of numbers. (JavaScript)
• PublicDatasetAndStatistics - Investigations into statistics on French Government public data, such as elections. (HTML, JavaScript, Python)
• reachouttrack-landing - Static landing page for ReachOutTrack, served from GitHub Pages at www.reachouttrack.org. (HTML)
• wcs-poc - Interactive demo of a Warehouse Control System: order dispatching from a simulated WMS, AGV / conveyor / sorter simulation and storage-slot management, live on GitHub Pages. (HTML)

• Languages: C++, C#, .NET, Python, TypeScript, JavaScript (ES6+), Vue 3
• Concepts: API Integration, Software Architecture, Automation, Performance Caching, Agility
• Workflows: Git, Pull Request Reviews, Continuous Collaboration, AI-assisted development
• Methodology: Moving from Waterfall to Agile (Scrum/Kanban) for Engineering and Hybrid Agile for Implementations
• Cloud: Private to Public Cloud (AWS, GCP)
