Full-stack developer and data engineer with 6 years of development experience, the last 4 as a freelancer. I build B2B SaaS, back offices and data pipelines — real estate, urban planning, energy renovation — and keep them running in production.

What people say

“Arthur has now been working with us at Stakimo for a year and a half, and I can honestly say we are lucky to have him on our team.

Arthur is an excellent full-stack developer, but reducing him to his technical skills would really sell him short. He understands very quickly, communicates very well and always takes the right stance. I entrusted him with several important and complex topics, which he carried through on his own. With him, I know things will be done right, and that trust is extremely valuable.

What I particularly appreciate about Arthur is that he never settles for just executing. He dares to challenge business needs when he thinks a better solution is possible. He is also constantly thinking about how to improve the way we work, our technical choices and our delivery process. He is very open, shares his ideas with others and often gives us genuinely relevant advice.

At a time when AI is transforming our profession, Arthur has already fully embraced this new way of working. He doesn’t just use it to be more efficient in his own tasks; he also understands how to integrate it intelligently into the whole delivery process so the team benefits from it.

Personally, I really hope we will have many more opportunities to work together in the years to come.

And if another company or team ever gets the chance to work with him, I can simply tell them this: seize the opportunity. Arthur will bring you far more value than you could imagine, and will far exceed your expectations.”

Thomas Cao
Co-founder of Stakimo

“I’ve had the opportunity to work with Arthur three times: at Meilleurs Agents, then more recently, at my initiative, on two engagements at Abrico and Qomon.

Arthur is an autonomous and particularly dependable developer who doesn’t shy away from complex or gruelling tasks. As a bonus, he has a real entrepreneurial streak.

Over our collaborations, I’ve also seen steady progress in how he works with teams and communicates about his topics, which makes him an increasingly effective collaborator and our collaborations enjoyable.

I recommend Arthur without hesitation for full-stack or back-end work that calls for autonomy, reliability, and a sense of responsibility and execution.”

“I worked with Arthur on building a complex data-ingestion system for two years, and he performed well on every front: defining the needs, architecting and planning the project, development and maintenance. Arthur listens and cares about delivering the right technical solution. I highly recommend him!”
