Freelance Lead Data Scientist – Start within 1–2 weeks. Contract: 1 month (strong potential to extend). Day rate: £600/day. Location: Remote (UK-based preferred; onsite for initial days).

We’re supporting a major client on a short, high-impact project that blends computer vision, NLP, and marketing analytics. The goal is to refine and optimise an existing model that predicts the conversion rate of marketing images based on their visual and contextual attributes.

• 
  
• Enhance or rebuild an existing multimodal image-to-text model built using CLIP and Phi (OpenAI).
  
• Apply SHAP (or similar explainability methods) to attribute what’s driving conversion — e.g., the presence of people, objects, or scene context.
  
• Extend an interactive Python Dash web app that visualises image predictions and their drivers.
  
• Work closely with the analytics and marketing teams to make the tool usable, explainable, and business-ready.
  
• Handle both model optimisation and dash app refinement, focusing on interpretability and usability.

• Hands-on with multimodal data (images + text) preferred.
  
• Comfortable in a fast-moving, creative environment; self-starter with a growth mindset.
