I Built a Free Platform to Learn DSA, System Design, LLD, AI Engineering, Java, Python, and C++ in One Place

As a software engineer preparing for interviews, I faced a frustrating problem.

Learning resources were scattered everywhere.

  • DSA on one platform
  • System Design on another
  • Low Level Design somewhere else
  • Java and Python documentation elsewhere
  • AI Engineering spread across blogs and YouTube videos

I constantly switched between tabs, notes, courses, and bookmarks.

So I decided to build something for myself.

Today, that project has grown into ReviseAlgo.

What is ReviseAlgo?

ReviseAlgo is a developer learning platform focused on:

Data Structures & Algorithms

Learn interview-focused concepts such as:

  • Sliding Window
  • Two Pointers
  • Binary Search
  • Dynamic Programming
  • Graphs
  • Trees
  • Heaps
  • Backtracking

Instead of just memorizing solutions, the goal is to understand patterns and problem-solving frameworks.

System Design

Topics include:

  • CAP Theorem
  • Consistency Models
  • Caching
  • Sharding
  • Message Queues
  • Distributed Systems
  • API Design
  • Databases
  • Security
  • Monitoring

Along with real-world system design case studies such as:

  • Instagram
  • Uber
  • WhatsApp
  • Netflix
  • YouTube
  • TinyURL

Low Level Design

Covering:

  • SOLID Principles
  • Design Patterns
  • UML
  • OOP Fundamentals
  • Machine Coding Style Problems

AI Engineering

One of the fastest growing interview domains today.

Topics include:

  • LLM Fundamentals
  • RAG
  • GraphRAG
  • AI Agents
  • MCP Protocol
  • LangGraph
  • Prompt Engineering
  • Fine Tuning
  • Inference Optimization
  • Agent Memory

Programming Languages

Complete learning tracks for:

  • Java
  • Python
  • C++

From beginner concepts to advanced topics such as concurrency, memory management, JVM internals, templates, reflection, streams, and more.

Why I Built It

Most platforms focus on a single area.

I wanted a place where a software engineer could follow a complete roadmap:

  1. Learn a programming language
  2. Master DSA
  3. Learn Low Level Design
  4. Learn System Design
  5. Understand AI Engineering
  6. Prepare for interviews

All from a single platform.

Current Focus

I'm continuously improving:

  • Visual explanations
  • Interactive learning
  • Interview-focused content
  • AI Engineering resources
  • Mock interview experiences

Feedback Welcome

This is still a work in progress, and I'd love feedback from fellow developers.

What would make a platform like this more useful for your learning journey?
