    I have a raw customer dataset and I need a predictive model that can automatically segment these customers into actionable groups. The job begins with cleaning and preparing the data, moves on to feature engineering, and culminates in training and validating a segmentation model in Python—ideally using pandas, scikit-learn (or similar), and clear visual output via matplotlib or seaborn. What matters most is accuracy and interpretability. I want to understand which features drive each segment, so well-commented code, concise documentation, and an executive-level summary of insights are essential. Final deliverables should include: • A reproducible Python script or notebook • The trained model (saved or easily retrainable) • A brief report highlighting key segments...

    I need a machine-scraped contact database for Romanian companies operating in five clearly defined sectors: design offices & architects, locksmithing & metalworking, electrical installations, stonemasons, and carpentry. Each record must contain exactly three fields—company name, phone number, and email address—delivered in a single Excel file. Feel free to pull the information from company websites, reputable business directories, and social-media business pages; those three sources together should give the breadth I’m after. A basic validation of phone numbers and email syntax is enough, as long as obvious bounces or malformed entries are removed. Volume is critical.
