overview.
Built VibeCode, an AI-powered browser IDE enabling developers to write, execute, and preview full-stack applications without local environment setup. Engineered a secure execution environment using Docker, Node.js, and Redis.
about.
VibeCode is a cloud-based development environment that brings the full power of a local IDE to the browser. With AI-assisted code generation, live preview, and terminal support, developers can build and deploy applications entirely from their browser.
technical implementation.
Secure Execution Environment
Built isolated Docker containers for each user session with resource limits and network restrictions. Containers are automatically cleaned up after inactivity to prevent resource exhaustion.
Real-Time Collaboration
Implemented WebSocket-based live synchronization using Redis Pub/Sub for message broadcasting. Supports multiple concurrent users editing the same project.
AI Code Generation
Integrated AI models for context-aware code suggestions, code completion, and natural language to code translation. Optimized response streaming for low-latency UX.

challenges & solutions.
Challenge: Managing secure, isolated code execution at scale
Solution: Implemented Docker containerization with strict resource limits, network policies, and automatic cleanup. Each user gets an isolated environment that's destroyed after the session.
Challenge: Low-latency code execution and preview
Solution: Used WebSockets for real-time communication and Redis for fast message queuing. Implemented optimistic UI updates while code executes in the background.
