Freelancer profile translated to English.
Back to original languageAbout Alexandre
Freelance Python/Django developer, specializing in the design of web applications, APIs, and AI solutions integrated with concrete business needs.
I support companies in creating LLM-based solutions: RAG systems, business chatbots, internal assistants, AI agents, workflow automation, and integration of generative AI into existing applications.
I have already worked on RAG and agentic chatbot architectures, with concrete issues of document retrieval, vectorization, orchestration, response quality, source traceability, and backend integration. My goal is not simply to "connect an OpenAI API," but to build reliable, maintainable, and truly usable solutions for teams.
My primary technical foundation remains Python/Django, which allows me to integrate these AI components into production environments: REST APIs, dashboards, backoffice, asynchronous tasks, documentation pipelines, databases, Docker, Celery, RabbitMQ, and third-party services.
What I can bring to your projects:
- Development of tailor-made web applications with Django
- Creation and maintenance of REST APIs
- Automation of business processes in Python/n8n
- Refactoring, technical audit, and improvement of existing code
- Setup of Docker/DevOps environments
- Integration of third-party services and software solutions
- Technical support on architecture and stack choices
- Creation of RAG systems on internal documents
- Creation of AI agents to automate internal tasks
- Industrialization of PoCs into a maintainable solution
I favor projects where quality, technical clarity, and long-term reliability truly matter.
