See what our community has to say about Revise Algo.
"Revise Algo's System Design course is pure gold. It helped me clear my final rounds at Amazon. The explanations of scalable architectures are straightforward and entirely practical."
Software Engineer II, Amazon
"The LLD patterns combined with the Blind 75 DSA roadmap gave me exactly the structured path I needed. I successfully landed an SDE role at Microsoft thanks to this free resource."

I built Revise Algo because I believe high-quality engineering education should be free and accessible to everyone. My mission is to demystify complex concepts in Data Structures, Algorithms, and System Design to help you ace your interviews and build world-class software.
Everything you need to know about Revise Algo.
Yes, Revise Algo offers entirely free, high-quality programming tutorials covering Data Structures, Algorithms, System Design, and Low-Level Design. We want to make world-class computer science education accessible to everyone.
Our core tutorials focus on Java, Python, and C++. The concepts in DSA and System Design are universally applicable, but our code examples will allow you to learn language-specific best practices.
Absolutely. Our platform is structured to follow the highly effective Blind 75 and LeetCode 150 study plans, augmented with comprehensive System Design and LLD content specifically curated for top tech company interviews.
If you're completely new, we recommend starting with your preferred programming language tutorial (Java, Python, or C++), followed by the fundamental Data Structures like Arrays and Linked Lists.
Join thousands of developers mastering programming concepts from zero to one. Start learning today and transform your career.
Revise Algo is your complete free resource for mastering programming, data structures, algorithms, and software engineering concepts.
Our Data Structures and Algorithms course covers everything from basic arrays and linked lists to advanced concepts like dynamic programming, graph algorithms, and tree traversals. Practice with Blind 75 and LeetCode 150 problems used by top tech companies including Google, Amazon, Microsoft, and Meta for their coding interviews.
Learn to design scalable distributed systems like Netflix, Twitter, WhatsApp, and Uber. Our system design tutorials cover essential concepts including load balancing, caching strategies, database sharding, microservices architecture, message queues, and CAP theorem that are crucial for senior engineering interviews at FAANG companies.
Master Low-Level Design (LLD) with practical implementations of SOLID principles and all 23 Gang of Four design patterns. Learn to design parking lots, elevator systems, chess games, and more with clean, maintainable code that follows industry best practices and object-oriented programming principles.
Learn programming in Java, Python, and C++ with language-specific tutorials and code examples. Whether you are preparing for a backend development role using Java Spring Boot, a data science position with Python, or competitive programming with C++, our platform has you covered with comprehensive tutorials from beginner to advanced levels.
Every topic is designed with technical interviews in mind. We provide common interview questions, time and space complexity analysis, multiple solution approaches, and tips from engineers who have cracked interviews at top tech companies. Practice coding problems with our interactive code playground that supports multiple programming languages.
Follow our carefully crafted learning roadmaps that guide you from complete beginner to interview-ready developer. Each roadmap provides a clear path with estimated timelines, prerequisite knowledge, and milestone checkpoints to track your progress. Start with fundamentals and gradually advance to complex topics at your own pace.
