About Jérémy

Jérémy Barot – Full Stack and AI Engineer


My Background
For over 8 years now, I have been developing web and mobile applications, notably for Carrefour, Renault, Houra, local authorities, and several tech startups. This mix of large accounts and startups allows me to adapt the level of robustness to the context: an application or an AI integration to validate a product hypothesis is not written the same way as a system intended for 10 million users.

My Current Positioning:
Helping companies integrate AI into their products or processes, by leveraging a solid mastery of classic development underneath.
Concretely, this means I can both build your Next.js / Python app from scratch, and connect LLM agents, RAG on your documentation base, or n8n workflows that automate what your teams do manually today.
The difference with a purely AI profile is that I also know how to ship the product around it, not just the PoC.

What I Can Do
Web applications in Next.js / React / Python (FastAPI, Django)
Mobile applications in React Native, Flutter, Swift, Java, Kotlin
Integration of LLMs into existing or new products: chat, agents, RAG, content generation
Automation of business workflows with n8n for example, connected to LLMs if needed
Secure REST APIs, PostgreSQL / MongoDB databases, vector stores
CI/CD, continuous deployment, clean production deployment

How I Work
Based in Sarthe, fully remote anywhere in France and internationally (fluent in English). I prefer missions where I can understand the need before coding, and where the team is open to dialogue.
