Losing money on your Data projects? Here's why.
The problem isn't technical.
Former Head of Data Science at Jow (App #5 AppStore - Food Category, 5 Million Users), I deployed 50 algorithms and data pipelines.
I supported 10 teams in media, retail, SaaS, and healthcare.
And here's what I discovered: Data teams don't lack skills.
They lack clarity.
What might be holding you back:
❌ Projects getting stuck for weeks
❌ Dashboards nobody uses
❌ Technical debt paralyzing the team
❌ Bugs discovered a month later
❌ No visibility on what truly adds value
The result:
Your management loses confidence.
Your business teams are frustrated.
And you're juggling emergencies without accomplishing anything significant.
What I bring:
✅ Clarity: identifying what's really blocking progress (often, it's not what you think)
✅ Prioritization: knowing which projects to launch to generate measurable ROI
✅ Execution: implementing the pipelines, algorithms, and automations that turn your Data into a business lever
My skills:
- Machine Learning & AI Engineer (recommendation, prediction, personalization)
- Data Engineering (ETL, infrastructure, automation)
- Analytics & large-scale AB testing
- Data Architecture (refactoring, scalability, technical debt)
Throughout my 10 team support experiences, I learned that technical skills are never enough.
What matters is understanding business challenges, asking the right questions, and delivering what will have an impact.
Client results:
"The data team's efficiency has drastically increased" — Eric, CEO GC Tech
"Data vision serving business challenges" — Nicolas, Head of Retail Jow
Let's talk about your Data challenges.
