Description

Built a sophisticated full-stack code editor with real-time execution capabilities, integrated file system, and terminal access in a containerized environment.

Tech Stack

ReactNext.jsMonaco EditorDockerExpressWebSocketsTypeScript

Implementation

Developed a comprehensive development environment that combines a feature-rich code editor with real-time file operations, output preview, and integrated terminal access. Implemented Docker containerization for secure code execution and environment isolation, along with a multi-container architecture to coordinate file server, terminal service, and frontend components in a unified experience.

Note: Due to the costs associated with running Docker containers in production, this feature is currently not available for live demonstration.

B

Interactive Code Editor (Instant Code Runner)

Description

Developed an interactive code editor that allows students to write, run, and get feedback on their code directly in the browser.

Tech Stack

ReactMonaco EditorWeb WorkersTypeScriptKafkaDocker

Implementation

Integrated Monaco Editor with a custom execution environment that safely runs JavaScript code. In the background, we utilize Apache Kafka for message queuing and Docker for containerized code execution, enabling our Instant Code Runner to scale seamlessly and execute code in isolated environments. Added syntax highlighting, error checking, and a responsive design that works across devices.

C

AI-Powered Chat Interface

Description

Implemented an AI chat system that helps students with coding questions and provides contextual assistance throughout the learning journey.

Tech Stack

ReactWebSocketsAI IntegrationTypeScript

Implementation

Created a real-time chat interface that connects to an AI backend. The chat maintains context across conversations and can understand code-related questions with appropriate formatting for code blocks.

D

Payment with Stripe

Description

Implemented a secure payment system using Stripe for course purchases and subscriptions with real-time transaction processing and automated billing management.

Tech Stack

Stripe SDKWebhooksNext.js API RoutesTypeScript

Implementation

Integrated Stripe's client and server SDKs to handle payment processing, with webhook handlers for asynchronous events like payment confirmations, refunds, and subscription renewals. Implemented both one-time purchases and recurring subscription plans with automatic invoicing.

E

Record Video Solution

Video demonstration of the Record Video Solution in action

Description

Developed a comprehensive video recording and editing system that allows instructors to create professional-quality video solutions with custom text overlays and timing controls.

Tech Stack

ReactPixiJSFFmpegNode.jsDockerTypeScriptExpress

Implementation

Built a full-featured video recording solution with screen and audio capture using react-media-recorder. Implemented a custom video editor with text overlay capabilities powered by PixiJS for client-side text rendering and FFmpeg for server-side video processing. The system includes features for overlay timing, text customization, and trimming controls in a containerized environment for secure and efficient video processing.
