As one of the top 5,000 freelancers and in the top 4% of professionals on this platform, I'm certain my skills can bring tremendous value to your React Native project. While I have extensive experience across multiple development areas, particularly in designing and developing native and cross-platform mobile apps, your project's central focus optimizing video playback aligns perfectly with my expertise. Having worked with over 150+ companies in their respective domains, including Android and iOS app optimization for low-end devices like the ones you mentioned, I understand the importance of creating an efficient video feed. I'm adept at reworking video delivery systems to load files in smaller chunks, such as those requested -so that videos load seamlessly despite weak devices or slow internet. Moreover, my experience with backend technologies such as Django and S3 enables me to efficiently handle the backend changes needed for the project. So whether it's improving autoplay logic or making significant backend changes (HLS or range-based chunk), you can rest assured that your video feed will be highly optimized, smooth, and production-ready once I'm done. If you're looking for a qualified professional who will take your project on head-on to deliver not just quantity but quality results, consider hiring me

Hello Hiring Manager, Your objective is very clear: turn an already-working Expo video feed into a highly optimized, TikTok/Threads-style experience that performs well on low-end devices and slow networks. This is a performance-engineering task, not a basic playback implementation—and that’s exactly where my experience fits. On the frontend (Expo / React Native), I’ll focus on: • Tuning FlashList for heavy media feeds (windowing, estimated item sizes, viewability configs, recycling behavior) so scrolling stays smooth with multiple videos in memory. • Implementing strict autoplay rules using visibility thresholds so only the currently visible video is mounted, decoded, and playing—everything else stays paused or unloaded to protect CPU and RAM. • Using chunk-based playback with Expo Video / AV (or migrating to a more suitable player if needed) to ensure fast start times and minimal buffering on poor connections. • Actively managing component lifecycles to prevent decoder leaks, excessive re-renders, and background playback. On the backend (Django + S3), I’ll deliver: • A streaming strategy using HLS (preferred for adaptive bitrate) or HTTP range-based chunking (~2-second segments) depending on your current pipeline. • Proper S3 configuration (byte-range support, caching headers, CDN readiness) so the app never pulls full video files unnecessarily. • Clean, scalable endpoints that support future feed growth without rework. Best regards,

As a seasoned React Native developer, I possess the skills in optimizing applications for low-end devices and slow internet connections, which is exactly what your project requires. My familiarity with Expo-based apps makes me well-versed in resolving video playback issues such as improving scrolling, changing video delivery to small chunks, and redesigning the autoplay logic -- all aiming for a streamlined and efficient user experience. Moreover, my extensive experience in delivering high-quality results even with limited resources has been proven to be incredibly valuable in situations like this. While I have specialized in digital marketing and automation primarily, my technical expertise extends to Android and iOS development as well as API integration - making me perfectly adept at handling Django backend changes and S3 integrations. Building systems that optimize performance and guarantee reliability is integral to what I bring to the table. So not only will you get someone proficient at writing code, but you'll also partner with an individual committed to transforming your app into a highly optimized video platform ready for a global audience.

I’m confident I’m the right person for this project, especially given your focus on a modern, smooth, and optimized video feed tailored for low-end devices and slow internet. Your need for automated, chunk-based video delivery and improved autoplay logic aligns perfectly with challenges I’ve tackled before. I bring strong skills in React Native, Django, and video streaming protocols like HLS. I’m new to Freelancer, but I have strong real-world experience and have completed many successful projects outside the platform. Let’s talk through your goals — I’d love to help bring this to life. Regards, Garron Levi Wallace

Hi, I specialize in performance optimization for React Native apps, especially with video-heavy components. I will: - Optimize `FlashList` for smooth scrolling with video items - Implement efficient video chunking (≈2s) for low bandwidth - Improve autoplay logic to reduce CPU/memory load - Adjust backend (Django + S3) to support HLS or range-based streaming You'll get a smooth, production-ready video feed optimized for low-end devices and poor networks. Clean, well-documented code and version-controlled via Git. Let’s make it efficient and scalable.
