Hello, I'm Julien, Digital Project Lead & Platform Builder Digital Ecosystems · Payments · Tenders · AI

I can support a contracting authority in delivering their project, or build the digital ecosystem hands-on. I have 15+ years of experience. I operate from Brussels, Belgium.

Services

What I enjoy doing

Whether I'm supporting a contracting authority or building the platform hands-on, I take digital projects end to end — across SaaS, payments and connected ecosystems.

I'm particularly drawn to projects with a social, cultural, philanthropic or ecological impact.

My approach is to turn something ambiguous into a clear, maintainable solution that people actually enjoy using.

Project leadership: End-to-end management of digital projects, from framing the need and planning through delivery to long-term operations.
Contracting authority support: Owner-side support for public bodies and private companies alike: framing the need, comparing offers and steering delivery, as an independent technical eye that keeps your project on track for deadlines, budget and quality.
Digital ecosystems & platforms: Custom platforms and digital ecosystems built with the analysis and robustness they deserve to grow without hassle, the end user always in mind.
Public tenders: Helping organizations write public tenders or RFPs and build winning responses, always with a realistic technical eye on what it takes to deliver.
Payment flows: Tailor-made payment flows — online, offline and marketplace — that are easy for customers and built to boost conversion.
Ticketing, attractions & events: Complex registration and access-control scenarios, plus cashless payment operations serving tens of thousands of happy guests.
Hardware, embedded & IoT: Bringing hardware into your ecosystem — RFID, NFC, printers, automatic gates and payment terminals — bridged seamlessly with software.
APIs, ERP & data: Combining data from multiple sources and integrating APIs, consolidating it into an ERP as a single source of truth, and turning datasets into dashboards and insights.
Process automation: Analyzing and building tools that automate the repetitive, so your team can focus on high-value work.
Performance & reliability: Making software fast, reliable and efficient — I analyze and optimize until we reach the sweet spot.
Video & streaming: Video distribution, live and on demand — low latency, on any device, anywhere.
User experience: In the end, the user decides. Putting them at the center of every decision is part of my quality standard.

AI in my workflow

Senior judgment, AI-accelerated

AI is now central to how I work — but what makes it effective is the 15+ years of experience behind it. I know when to trust it, when to challenge it, and how to direct it toward results that actually hold up in production.

The human touch — judgment, context, craft — is what turns AI from a shortcut into a genuine multiplier.

Analysis & specifications: Drafting functional specifications, requirements and technical documentation faster, so we spend more time on the decisions that matter.
Public tenders: Accelerating the research and first drafts for public tenders, so I can spend my time on strategy and technical fit.
Work, always reviewed: Everything AI produces — code, specs, drafts — gets read, checked and owned. AI speeds up the work; I stay responsible for the result.
Documentation & knowledge: Keeping documentation, onboarding and knowledge-sharing up to date without it becoming a chore.
Rapid prototyping: Standing up prototypes and proofs of concept fast, to validate ideas and de-risk decisions before we build for real.
Research & trade-offs: Weighing technical and architectural options with a fast, well-informed second opinion, so the important decisions are made on solid ground.

My standards

How I build

Tools come and go. What lasts is the judgment behind them — knowing what to build, what to leave out, and what will still hold up years from now.

These are the standards I hold every project to, whatever the stack.

Built to last: Architecture chosen for maintainability, not novelty. Systems that stay easy to understand and change years after launch.
Security & privacy by default: The highest industry standards baked in from the start, not bolted on afterwards.
Performance as a feature: Fast, reliable and efficient by design — measured and optimized, never assumed — because speed is part of the experience.
Connected by design: Open standards and clean APIs so platforms, payments and hardware talk to each other — and your data stays portable, never locked in.
Own the outcome: Accountable end to end for what actually runs in production, on deadline and on budget — not just what ships.
The right tool for the job: No dogma about languages or frameworks. I pick what fits the problem, the team and the years of maintenance ahead — fluent across a broad stack when it matters.

How to contact me

To get started, I encourage you to write me an email. I'm also available on the phone or for meetings if you prefer having a chat.

I speak French and English, and I'm glad to work on Flemish documents too — though I'll spare you my spoken Flemish.
