Study path at a glance
Six levels from orientation to large-scale products. Level 4 (tech guides) and Level 5 (OS / hardware) branch off when your role or a design requires them.
Follow solid arrows in order. Dashed lines = open only when needed (tech guides or specialized tracks).
Left: sample week-by-week pace. Right: how 172 posts split across categories.
| Level | Focus | Time | You can design… |
|---|---|---|---|
| 0 | Orientation | Week 0 | How interviews work; where to look things up |
| 1 | Fundamentals | Weeks 1–2 | URL shortener, rate limiter, parking lot, local chat |
| 2 | Distributed | Weeks 3–5 | Feeds, chat at scale, crawlers, KV store, pub/sub |
| 3 | Advanced | Weeks 6+ | Twitter, Uber, YouTube, schedulers, LLM-style APIs |
| 4 | Tech depth | On demand | Redis, Kafka, SQL, K8s — when a post names the tool |
| 5 | Specialized | Optional | OS frameworks, embedded, hardware test & DFT |

2. How this blog is organized
Skim the diagram, then use the tables — you do not need to read every post. Each design article includes architecture PNGs at the top; open a tech guide only when a design names a tool you do not know.
Top: three content tracks. Bottom: how sections on this page fit together.
Content categories
The big picture (30 seconds)
- Learn how to run an interview (framework, vocabulary, trade-offs).
- Practice classic design questions (URL shortener, chat, news feed, …).
- Look up technologies (Redis, Kafka, databases) only when a design needs them.
External courses (Hello Interview, ByteByteGo) pair well with this blog. Start with References and the study path above.
Recommended reading order
Solid arrows = recommended order. Dashed lines = open a tech guide only when that design needs it.
Five types of posts (and when to use each)
Every post on this blog fits one of these buckets. Section 3 lists them all.
| Type | What it is | When to read it | Title often looks like |
|---|---|---|---|
| Foundations & interview prep | How to think, what to say in interviews, book/course links | First 1–2 weeks of study | “Interview framework”, “References”, “CAP theorem” |
| System design problem | Step-by-step answer to “Design a X” (requirements → API → diagram → scale) | Main practice after foundations | “Design a URL Shortener”, “Design a Chat System” |
| Product-scale design | Shorter notes on a famous product (Twitter, GitHub, …) | Quick review or second pass on a topic | “System Design: Twitter”, “System Design: YouTube” |
| Technology guide | Deep dive on one tool (Redis, Kafka, PostgreSQL, …) | When that tool appears in a design you are studying | “Redis comprehensive guide”, “Apache Kafka guide” |
| OS / embedded prep | OS frameworks, JNI, devices, glass, Android native, hardware test & DFT | Only if your role is OS/middleware/embedded/validation hardware | “OS frameworks”, “Hardware design for testing” |
Not sure where to click?
| Your goal | Start here |
|---|---|
| I have never done a system design interview | Interview framework → URL shortener |
| I know basics; I want interview practice | Level 2 & 3 in the study path |
| I keep hearing “use Redis/Kafka” and feel lost | Technology quick reference → pick one guide |
| I want one long curated list | Learning path index |
| I need the full map of components | Distributed system ecosystem |
Why the same topic sometimes has two posts
This is normal. Use the rule that fits your situation:
A. Full guide + short notes (read the full one first)
The full post walks through requirements, APIs, scaling, and trade-offs. The short post is a quick recap—good for review right before an interview, not ideal as your first read.
| Topic | Read first (full) | Then review (short) |
|---|---|---|
| URL shortener | Full guide | Short notes |
| Rate limiter | Full guide | Short notes |
B. Simple version → harder version (go in order)
Start with the simpler problem, then read the scaled-up version.
| Start here | Then read |
|---|---|
| Web crawler | Distributed web crawler (10k nodes) |
| Social feed (local) | News feed (distributed) |
C. Product overview + focused deep dive (either order is OK)
One post covers the whole product; another zooms in on one piece (e.g. feed only).
| Product overview | Focused deep dive |
|---|---|
| System Design: Twitter | Design social media feed (Twitter) |
| System Design: YouTube (short) | Design YouTube (full) |
D. Index page → many linked posts
Some posts are tables of contents, not lessons themselves.
| Index (start here) | What it links to |
|---|---|
| Technology quick reference | All technology guides (Redis, Kafka, databases, …) |
| Learning path index | Level 1–3 design problems in study order |
| This page | Learning path + every post by category |
How designs and technologies connect
You do not read every technology guide first. Use this loop while you practice:
| Step | What to do | Example on this blog |
|---|---|---|
| 1 | Learn how to structure an interview answer | Interview framework |
| 2 | Pick one small design and read it end-to-end | URL shortener |
| 3 | If the post names a tool you do not know, pause and open only that guide | “cache” → Redis; “queue” → Kafka |
| 4 | Finish the design, then pick the next problem (repeat steps 2–3) | Rate limiter → News feed |
| 5 | After several designs, try larger systems | Twitter · Uber |
| 6 | Optional: see how pieces fit together | Distributed system ecosystem |
Practice loop: Interview basics → small design → unknown tool? open that tech guide → finish → repeat → larger systems.
How to read the diagram: Loop ② → ③ → ④ for each new problem. When ⑤ is “ready,” move to ⑥—usually after several small/medium designs, not the first week.
Optional: OS / embedded / hardware track
Only needed for OS framework, middleware, device, or hardware validation interviews—not for typical backend “Design Twitter” loops.
- OS frameworks guide
- 7-day prep todo
- Hardware design for testing & DFT — ATE/DUT fixtures plus silicon DFT (scan, BIST, JTAG)
