Freelancer profile translated to English.
Back to original languageAbout Antoine
Fullstack developer for over 5 years, I design and develop modern web applications, from architecture to production.
I am also a technical director and co-founder of a company specializing in access to law. There, I designed the entire technical architecture and developed most of the platform: web interfaces, services, APIs, document processing, information retrieval, and language model integration.
I specialize in designing RAG (Retrieval-Augmented Generation) systems that leverage document databases to create assistants capable of providing reliable answers based on a company's business data.
I work on both the creation of a complete product and the evolution of an existing application:
- custom web application development
- API and robust architecture design
- language model integration
- RAG system implementation
- document processing and indexing
- performance and cost optimization
- audit and technical support
I pay particular attention to code quality, maintainability, and performance. My goal is to design simple, reliable solutions tailored to business needs, rather than accumulating unnecessary technologies.
