Learn how real systems are built.
From algorithms to architecture.
DSA patterns, machine coding, and system design — explained with clarity, trade-offs, and real-world context.
Why indexedcode
Pattern-first
Learn reusable mental models instead of memorizing problems.
Engineering-grade
Aligned with real production systems, not shortcuts.
Built in public
Continuously refined with clarity and depth.
What You'll Learn
Data Structures & Algorithms
Patterns, complexity, edge cases
Machine Coding
Clean, extensible, testable code
Low-Level Design
SOLID, object modeling, design patterns
High-Level Design
Scalability, data flow, trade-offs
Learning Philosophy
- •Focus on why, not just how
- •Trade-offs over "best solutions"
- •Real constraints > idealized problems
- •Depth over breadth
This is how senior engineers think.
Early Access
Current Status
indexedcode is being built in public.
We're starting with DSA fundamentals and expanding into machine coding and system design.
