Portrait of Emmeline Chandes
  • NextGen Media
  • En Visite

“Elie supports me on all my IT topics, from building my websites to developing a SaaS tool, and a custom OS for my business.

What I value in our collaboration is his mindset: a strategic vision that goes far beyond that of a typical IT consultant. Elie works like a sparring partner, perfect for a solo founder like me.”

Emmeline ChandesFounder of En Visite, France's #1 PropTech podcast

Let's work together.

A project to launch, a decision to make or a team to train?

A custom project.

I design and build your website, software, AI agent or app, from MVP to finished product.

  • A fixed price, agreed before we start
  • A polished design, optimized and built around the user experience
  • Regular follow-up during the project, and after launch

An expert eye.

A project, a doubt, a choice of tool or provider: we take stock together, once or over time.

  • Technical audit and tool selection
  • Roadmap and budget estimate
  • Part-time tech support
  • Code review and hiring help

For teams.

For companies that want to know where AI will save them time, and make their teams self-sufficient with it.

  • AI audit and requirements modeling
  • On-site workshops, half a day or a full day
  • AI tool training, tailored to each role and workflow

A few good questions.

Not the ones you were looking for? Feel free to ask your own at the bottom of the list.

Mostly startups, solopreneurs and small, agile teams, in Belgium, France and across Europe. I also occasionally work with teams at larger companies on consulting or innovation projects.

Yes. I'm based in Brussels and happy to travel within Belgium and neighboring countries, but most projects run remotely, with regular video calls.

It all depends on the project. I adapt to your actual needs as well as your budget. What I build (website, software, AI agent or app) is quoted at a fixed price, set after a free first call. Consulting, audits and ongoing support are billed by the day or the hour.

It depends on the project. I commit to delivering a first usable version as fast as possible: very often within a few weeks, sometimes within a few days. It then evolves until launch, with regular progress updates.

Yes. I start with an audit of the code and the infrastructure, then propose a plan to stabilize, improve or evolve the product.

French, my native language, and English, which I speak fluently and in which I consume most of my technical content, written and spoken: both work just as well for conversations as for deliverables. I also get by in Spanish and know the basics of Dutch.
