Resources

Curated learning roadmaps, reference material, and practice routines designed to take you from fundamentals to senior-level system architect.

Learning Playbooks

  1. Foundations Sprint (2-3 weeks): Work through the opening categories of the HLD roadmap (networking, HTTP, databases). Pair each module with intro readings and daily estimation drills.
  2. Core Architecture Deep Dive (4-6 weeks): Focus on caching, queues, storage, and consistency. After each topic, reinforce the concept with a relevant case study (e.g., caching → URL shortener, messaging → notification service).
  3. Scalability & Reliability Lab (3 weeks): Practice sharding, multi-region design, observability, and SLOs. Use the search page to quickly revisit terminology and diagrams.
  4. Low-Level Design Accelerator (3-4 weeks): Follow the LLD roadmap. Implement 2-3 patterns per week, write UML diagrams, and rehearse API contracts by explaining them out loud.
  5. Interview Simulation Loop (ongoing): Schedule weekly mock interviews, rotate between HLD, LLD, and hybrid problems, and capture retrospective notes in a design journal.

Stage-Based Resource Stack

Foundation

Core Architecture

Scalability & Ops

Low-Level Design

  • Head First Design Patterns — apply to OOP principles
  • Refactoring.Guru pattern catalog
  • Implement mini projects (parking lot, rate limiter) after each pattern module

Interview Reps

  • System design prep guide timelines
  • Pramp / Exponent for mock interviews
  • Architecture paper summaries (e.g., DynamoDB, Spanner)

Tooling & Practice Habits

  • Diagramming: Excalidraw, Miro, or Whimsical. Save a template for system layout, data flow, and deployment views.
  • Estimation drills: Use a spreadsheet or Notion doc to capture daily capacity calculations (QPS, storage, bandwidth).
  • Architecture journal: Maintain a log of lessons learned, trade-offs, and interview feedback to surface patterns in your reasoning.
  • Deliberate practice: Rotate through case studies, time-box to 45 minutes, then critique using the system design checklist.
