Build Multi-Head ML Model

I'm seeking an experienced machine learning expert to develop a multi-head model using numeric data from CSV/Excel files. The model will have both classification and regression tasks, and is based on sequential and complex data where the output depends on multiple variables.

Key requirements:
- Expertise in building multi-head ML models
- Strong understanding of sequential and complex data
- Proficiency in handling numeric data from CSV/Excel
- Experience in both classification and regression tasks

Ideal skills and experience:
- Advanced knowledge of machine learning algorithms
- Strong programming skills in Python or R
- Experience with libraries like TensorFlow or PyTorch
- Background in data preprocessing and feature engineering
- Ability to interpret and validate model outputs

Please provide your portfolio and relevant experience.
