About Brian

Web Developer | Next.js | React | AI

Are you running asmall or medium-sized businessand your teams are spending too much time on manual tasks that no one has ever taken the time to automate?

I don't just codeweb applications**. I connect them to your existing tools so information flows automatically. **Next.js**, **React.js**, **TypeScriptfor the front,N8NandAIfor everything that can be **automated**.

Concrete results with my clients:

*Symeto(BTP SaaS, public procurement): Securing and improving theNext.jsandReact.jsplatform, integrating several AI analyses of application documents.Result**: **saving 5 man-days per month on the analysis and scoring of technical proposals for mediators.

*Agremate(**Next.js** andReact.jsplatform): Automatic task creation and voice command timer launch.Result**: **4 man-days recovered per month thanks to the elimination of manual data entry.

As aNext.jsandReact.jsweb developer, I primarily work with non-technical managers ofSMEsand agencies, on web development and automation projects (N8N, AI agents, RAG, document extraction).
