I am a technology executive and data platform architect with 15+ years of experience building, scaling, and structuring complex digital and data-driven systems.

Co-founder of ForePaaS (acquired by OVHcloud), I have led engineering, data, and QA teams, designed cloud-agnostic-scale data platforms, and delivered enterprise-grade systems for major organizations across multiple industries.

I now operate as a Fractional CTO and Data & AI Architect, helping startups and scale-ups structure their technical foundations, design scalable platforms, and integrate advanced data and AI capabilities into their products.

• Technical strategy & architecture for startups and scale-ups
• Design of scalable data platforms (ETL, DWH, distributed systems)
• Proprietary quantitative & machine learning systems
• AI / LLM integration into production-grade products
• Team structuring, process industrialization & delivery governance

Selected Experience

How I Typically Engage
