Drupal Enhancements & Stripe Integration

I have a small Drupal site that needs a focused round of improvements and I’d like everything wrapped up within a week. Here’s what I need done:

• Apply design, content, and functionality updates so the site looks fresher and runs more smoothly.
• Integrate Stripe as the payment gateway and confirm end-to-end transactions work in both test and live modes.
• Tidy up the database with an eye on performance optimisation (indexes, query tuning, cache configuration, etc.).
• Fix any minor bugs uncovered along the way and run a full round of testing before handing the site back.

You may use whatever workflow tools you prefer—Drush, Composer, or straight UI—as long as the final delivery is a fully working, tested Drupal install with the above points completed. Please include a brief note on similar Drupal projects you’ve handled, especially any that involved Stripe or database tuning.
