Structured Learning Timeline (2026)

Week 0: Language & Basics Refresh

  • Read/Write files and console I/O
  • String manipulation & Regular Expressions
  • 2D arrays and basic data handling
  • Processing CLI commands

Weeks 1–2: Data Structures & Algorithms

  • Complexity analysis (Big O notation)
  • Stacks, Queues, Heaps
  • Linked Lists
  • Trees and Tries
  • Graphs (DFS, BFS)
  • Hash Tables
  • Searching and Sorting algorithms

Weeks 3–4: Problem-Solving Practice

  • Solve basic to intermediate problems on platforms like LeetCode, HackerRank, or Codeforces

Weeks 5–6: Intro to Systems Concepts

  • Network setup for redundancy and maximum throughput
  • Load balancing fundamentals
  • Database replication and sharding basics
  • OS concurrency (threads, processes, locks, synchronization)

After the initial 6 weeks, continue with deeper dives into the core topics (OS, Networking, Databases, Architecture) throughout the year, combining reading, videos, labs, and personal projects. Prioritize Designing Data-Intensive Applications and Microservices Patterns for scalable system design.
