Back to original languageAbout Alexandre
Freelance Python/Django developer, specializing in the design of web applications, APIs, and AI solutions integrated into concrete business needs.
I assist 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 core technical foundation remains Python/Django, which allows me to integrate these AI components into production environments: REST APIs, dashboards, backoffice, asynchronous tasks, document pipelines, databases, Docker, Celery, RabbitMQ, and third-party services.
What I can bring to your projects:
- Custom web application development with Django
- Creation and maintenance of REST APIs
- Business process automation in Python/n8n
- Refactoring, technical audit, and improvement of existing code
- Setting up 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 prioritize projects where quality, technical clarity, and long-term reliability truly matter.
