your experience is actually pretty strong because you have solid metrics, but you should cut the bullet point about collaborating in standups since that is expected for any intern and doesn't show technical impact, you can replace that spave with a bullet about a specific technical challenge you solved like handling concurrency or database scaling, also your technical skills section is a bit cluttered so consider grouping them by category like languages, backend, and infrastructure to make it easier for a recruiter to scan, overll you have a good foundation so just focus on highlighting the hard engineering problems you tackled instead of process-based tasks
