System Design Notes
A growing home for system design concepts, technical lessons, and the small engineering insights worth remembering.
Roadmap
A timeline that never ends
System design learning is less like finishing a checklist and more like growing judgment. The timeline keeps moving because the systems keep changing.
- 01
Foundations
Scale, latency, throughput, availability, consistency, and core trade-offs.
- 02
Networking
DNS, HTTP, load balancers, CDNs, proxies, and API gateways.
- 03
Data Systems
SQL, NoSQL, indexes, replication, partitioning, and durability.
- 04
Distributed Systems
Queues, caches, consensus, idempotency, backpressure, and retries.
- 05
Reliability
SLOs, observability, rate limits, failover, and graceful degradation.
- 06
Architecture Practice
Capacity estimates, diagrams, trade-off calls, and design reviews.

- Generics notes
Working agreement
Keep the source. Improve the explanation.
The original repository remains the historical notebook. This site will gradually turn those topics into concise, original, well-organized study material.
