Secure Online File Conversion Platform Development

We are seeking an experienced web developer to create a robust and secure online file conversion platform. The primary functionality will include converting various file types, such as PDF to Word, Word to pdf, jpg to png, and other common document and image formats. The platform must prioritize user data security and privacy, ensuring all uploaded files and converted outputs are handled with the highest level of confidentiality and are automatically deleted after a set period. The user interface should be intuitive and easy to navigate, allowing users to upload files, select conversion options, and download results seamlessly. Key considerations include efficient conversion processing, scalability to handle multiple concurrent users, and a strong emphasis on data protection protocols.
