I'm an 17-year-old self-taught developer from India passionate about:
- Full-stack engineering
- Mobile app development
- Backend architecture
- Multimedia systems
- AI-powered search systems
- Product engineering
- Performance optimization
- Building large-scale platforms from scratch
I started learning development independently and built real-world systems instead of only following tutorials.
My biggest project is Knowzup — a multimedia knowledge-sharing and problem-solving platform designed to help users share knowledge using:
- Text
- Images
- Videos
- (Future audio support)
I developed the platform solo on a government-gifted 2011 HP laptop with almost zero budget.

Knowzup is designed to combine:
- knowledge sharing,
- multimedia communication,
- technical discussions,
- creator interaction,
- and community-driven learning
into one ecosystem.
Instead of limiting users to plain text, Knowzup allows users to communicate visually and interactively.
Users can create:
- Text posts
- Image posts
- Video posts
Future updates will also support:
- Audio content
Replies support:
- Text
- Images
- Videos
This allows users to:
- explain problems visually,
- provide tutorials,
- demonstrate solutions,
- and share knowledge more effectively.
Knowzup separates content types for better discovery and sorting.
Users can create:
- Questions
- Answers
- General posts
Replies are also categorized separately.
This improves:
- search quality,
- content organization,
- user experience,
- and feed relevance.
Implemented systems for:
- Upvotes / downvotes
- Reputation scoring
- Community trust indicators
Each user builds credibility through contributions.
Developed:
- Vector-embedded semantic search
- AI-based search suggestions
- Intelligent discovery systems
The platform is focused on understanding content meaning instead of only matching keywords.
Integrated AI systems for:
- Content summaries
- Search assistance
- Related content suggestions
- External support links
Built:
- Push notifications
- In-app notifications
- Email reminders & notifications
Developed customized video playback systems focused on:
- better UX,
- multimedia interaction,
- and performance optimization.
Implemented:
- JWT authentication
- Refresh token flow
- Rate limiting
- Protected APIs
- Admin controls
- Moderation systems
Security has been heavily prioritized from the beginning.
- Google One Tap Sign-In
- Email authentication
- OTA updates
- Crashlytics integration
- Analytics systems
- Save/bookmark system
- User profiles
- Channel pages
- Follow system
- Copyright reporting
- Reporting & moderation
- Feedback systems
- Feature request systems
- Help & support infrastructure
- Settings management
- Dark & light themes
- Clean minimalist UI architecture
And many more systems still under development.
- React Native
- Expo Bare Workflow
- TypeScript
- JavaScript
- Node.js
- Express.js
- REST APIs
- MongoDB
- MySQL
- JWT
- Refresh Tokens
- Rate Limiting
- API Protection
- Semantic Search
- Vector Embeddings
- AI Summarization
- Firebase
- Crashlytics
- Analytics
- OTA Updates
- Git & GitHub
Building Knowzup taught me much more than coding tutorials ever could.
I learned:
- Backend architecture
- Scalability thinking
- API design
- Multimedia handling
- Product engineering
- Security-focused development
- UI/UX systems
- State management
- Search systems
- Community moderation
- Real-world debugging
- Performance optimization
- Long-term product execution
I prefer:
- building real systems,
- learning deeply,
- solving difficult engineering problems,
- and understanding how products actually work internally.
I care more about:
- architecture,
- performance,
- scalability,
- and execution
than temporary hype.
Currently exploring:
- Advanced backend systems
- AI integration
- Semantic search architecture
- Custom native modules
- C++ integrations for React Native
- Audio/video processing
- Large-scale app optimization
