Full Stack SSL Certificate Checker Assignment Overview You are tasked with creating a full stack web application that checks and validates SSL certificates for given domain names. This application will help users verify the security and validity of SSL certificates used by websites.

Submission Guidelines Provide a link to a Git repository containing your project. Include a README.md file with: Setup and run instructions A brief explanation of your technology choices Any assumptions or design decisions you made Known limitations or areas for improvement (Optional) Deploy the application and provide a live demo URL. Evaluation Criteria Your submission will be evaluated based on the following criteria: Functionality: Does the application meet all the specified requirements? Code Quality: Is the code well organized, readable, and maintainable? User Experience: Is the interface intuitive and responsive?
