LeetLow

A backend-focused coding platform designed to handle secure code execution and scalable architecture.

Overview

LeetLow is a backend-driven coding practice platform inspired by modern competitive programming environments.
It is designed to provide a robust and secure backend system for managing coding problems, executing user-submitted code, and ensuring scalability for large user bases.

The platform focuses on backend performance, security, and scalability.

LeetLow is currently under active development, with the backend architecture being built and optimized.

Tech Stack

Node.js
Express
MongoDB
Custom Code Execution Engine (In Progress)
Docker (for containerized execution environments)

Why I Built This

I wanted to build a backend system that powers a structured platform for practicing DSA in a secure and scalable way.

While there are many coding platforms available, I wanted to understand how such systems work internally — from secure code execution to scalable backend architecture.

LeetLow is also a deep dive into backend design principles, including database optimization, API design, and execution logic for handling user-submitted code.

Features (In Progress)

Secure backend architecture for code execution
Scalable database design for managing problems and user data
API endpoints for problem management and user submissions
Containerized environments for isolated code execution

Some special backend features are currently under development and will be revealed at launch.

Current Status

Backend architecture under active development
Core database structure completed
Code execution system being implemented

Future Plans
