About Tanguy

Doctor in Artificial Intelligence from École Polytechnique, ex-CTO & co-founder (Entrepreneur First and Station F), I design and develop web applications, AI agents, and data/AI systems,from simple and quick projects to execute to complex platforms deployed at scale.

I notably built an AI SaaS platform deployed in over 20 operational environments, with a time-series forecasting engine driving over 200 daily streams, 99.9% availability, and measurable business gains (+5 to 15% productivity, automation equivalent to ~1 FTE per site).

👉 I also undertake lighter or more targeted projects, without unnecessary complexity:

• Simple web apps (POC, MVP, dashboards, internal tools)
• AI Agents (LLM, business agents, internal copilots, intelligent automation)
• Process automation and data workflows
• Optimization and automation algorithms
• Data pipelines, Python scripts, APIs
• Improvement, reliability, or deployment of existing systems

My approach is pragmatic and impact-oriented:the right level of AI and technology to serve the business need, without over-engineering.

I work end-to-end:
• Product & technical scoping
• Backend / data / cloud architecture (AWS, GCP)
• AI Agents, ML, optimization, automated decision-making
• Deployment, MLOps, monitoring
• Development of business-oriented web applications

What my clients appreciate:
• Quick understanding of complex issues
• Ability to simplify and secure technical choices
• Complete autonomy, from scoping to delivery
• Robust, scalable, and truly useful solutions

Whether you need a targeted AI agent, a simple and efficient tool, or an advanced intelligent system, I adapt to your context and priorities.
