Need Google Analytics / GA4 Expert to Compare Performance Before & After New Website Launch

We recently launched a new website and need help putting together a presentation that clearly shows the differences in Google Analytics / GA4 performance before and after the launch. We are looking for someone who can review GA4 data and create a clean, easy-to-understand presentation that compares key metrics such as: - Website traffic before vs. after launch - Users, sessions, engagement rate, and key events/conversions - Landing page performance - Source / medium performance - Organic traffic changes - Any major improvements or declines - Recommendations or insights based on the data The final deliverable should be a presentation we can share internally and/or with a client. It should not just be a data dump — we need someone who can interpret the numbers and explain what changed in plain English.
