Founder of HEXAIT, a software engineering studio in Paris. I design and develop custom web and SaaS applications, from scoping to deployment.
Graduate of ESIEE-Paris and former DevOps engineer at Rexel, I founded HEXAIT to support startups and SMEs that need a senior technical partner — not an army of juniors.

• StratGen — AI-powered collaborative SEO management SaaS
💡 What I bring:
• Web and SaaS application development (React, Next.js, Node.js, Python)
• Scalable cloud architecture (Azure, AWS, Docker)
• Functional prototype in 7 days, MVP in 6 weeks
• You own 100% of the source code
🎯 Typical missions:
• Create an MVP / SaaS from A to Z
• Replace an internal tool (Excel, Google Sheets) with a custom application
• Technical audit and takeover of an existing project
