Freelancer profile translated to English.
Back to original languageAbout Joshua
Do you have an AI need but no in-house Data Scientist?
I develop concrete and operational solutions for you.
My interventions cover three use cases:
- Chatbots and AI assistants on your internal data (RAG, text-to-SQL, LLM)
- Classification and prediction models (NLP, Computer Vision, ML/DL)
- Automation of business processes via Python and AI agents
What you receive:
A deployed application, a documented API, or an operational pipeline. Clean code, versioned, maintainable by your teams.
I place great importance on human contact to fully understand your needs and deliver exactly what you expect.
Also, I only work on one mission at a time: you benefit from all my attention and full availability from the beginning to the end of your project.
Available by message, video call, or in person.
Example of a possible project:
Real-time prediction application deployed on AWS, testable online at this link: velibtrend.streamlit.app
