An app which allow user to post their content accross multiple social media. I've built the mobile app, and implemented huge UI expectations.
PROJECT
_05
Framework
- React Native
- Jellypush
The project I am most proud of is Jellypush, which I built while working at Jellysmack, a social media platform that enables users to share short videos and connect with others.
I was responsible for the mobile app development and performance optimization.
He’s incredibly dedicated, putting in the kind of work that takes talent to the next level. His attention to the smallest details when implementing products is something you don’t come across every day.

Challenges & Solutions
- High design expectations: The app had to meet ambitious design standards, with a strong focus on smooth animations and transitions. I collaborated closely with the design team to align implementation with their vision.
- Used Skia for performant image processing and rendering.
- Fine-tuned animations with Reanimated and Gesture Handler.
- Performance optimization: The app needed to load quickly and run smoothly, even with a large number of users and videos. I optimized the code, images, and assets to reduce loading times and improve performance.
- Improved list rendering performance.
- Optimized image sizes and formats.
- Implemented lazy loading for images and videos.
- Scalability: The app architecture had to support a growing user base and an expanding video library.
- Implemented Map data structures for user and video data.
- Used efficient algorithms and data structures to minimize processing time.
- Optimized network requests with pagination, lazy loading, and WebSockets.
- Cross-functional collaboration: I worked closely with the backend, design, and product teams to ensure the app met requirements and deadlines.
- Maintained regular communication across teams.
- Applied agile development methodologies.
- Provided clear documentation and research for smooth handoffs.
- User engagement: Retention and satisfaction were key priorities, requiring features that encouraged continued use.
- Implemented push notifications to keep users informed and engaged.
- Leveraged analytics to track user behavior and guide improvements.
- Added social sharing features to encourage content distribution.
