Convert Elementor Section/Column Layout to Flexbox Containers (20 Pages, Elementor Pro)

I’m looking for an experienced Elementor developer to upgrade my website from the old Section/Column structure to the modern Flexbox Container layout. Website (shortener link): https://1damw5d.s.gy/upworktask The website is built with Elementor Pro and contains approximately 20 pages, with one key page translated into 10 languages using WPML. Scope of Work * Convert all Elementor Sections and Columns to Flexbox Containers. * Preserve the existing design, layout, and functionality. * Review and clean up unnecessary code, containers, and layout elements where appropriate. * Optimize the page structure for better maintainability and performance. * Test and optimize responsiveness across: * Desktop * Tablet * Mobile * Fix any spacing, alignment, overflow, or layout issues that occur during the migration. * Ensure all forms, menus, popups, and other website functionality continue to work correctly. * Verify that all WPML translations remain functional after the migration. Performance Optimization As part of the project, please: * Measure website performance before and after the migration. * Report any improvements in page speed, DOM size, and overall page structure. * Remove unnecessary elements and improve code cleanliness where possible. * Recommend any additional Elementor or performance optimizations that would benefit the website. Requirements Please do not rely solely on Elementor's automatic conversion tool. All converted pages should be manually reviewed and tested to ensure the layouts remain correct across all devices. In Your Proposal Please Include 1. Your experience converting Elementor websites from Sections/Columns to Flexbox Containers. 2. Experience working with Elementor Pro and WPML. 3. Estimated number of hours required for this project. 4. Examples of similar projects you have completed. 5. Any risks or issues you anticipate based on the scope above. I am looking for someone who pays close attention to detail and can complete the migration while maintaining design consistency and improving the website's overall structure and performance.
