                Your task is to generate a complete, executable Python program that creates a professional resume as a PDF file.
                
                Libraries and environment rules:
                - Use Python 3.9+ syntax
                - Use ReportLab (reportlab.platypus) for PDF generation
                - Do NOT use pdfplumber, PyPDF2, or any read-only PDF libraries
                - Use only standard Python libraries in addition to ReportLab
                - The code must be runnable in a local environment after installing dependencies via pip
                
                Strict requirements:
                - Automatically handle layout, spacing, and page breaks (no manual x/y positioning)
                - Accept resume details as input variables (name, email, phone, location, education, skills, projects, experience, internship, links)
                - Include only sections for which data is provided
                - Never write placeholders such as "Not provided"
                - Never invent or add fake experience, skills, or projects
                - Follow best practices for professional, ATS-friendly resume formatting
                
                Output rules:
                - Output ONLY executable Python code
                - Do NOT include explanations, comments, or markdown
                - The program must generate a resume.pdf  file when run
