Real World Projects
Stop watching tutorials. Start building systems from scratch.
Build URL Shortener
Hashing, collision handling, redirect logic — a tiny Bit.ly from scratch in Python.
Build Tiny Redis
In-memory key-value store with persistence, TTL, and a custom TCP protocol.
Build HTTP Server
Raw sockets, HTTP/1.1 parsing, routing — built from scratch without any framework.
Build Cache System
LRU, LFU, and write-through implementations with eviction policy comparison.
Build Chat App
WebSockets, rooms, real-time broadcasting, and Redis pub/sub messaging.
Build File Uploader
Chunked uploads, progress tracking, and resumable S3-compatible file storage.
