Dear Codenight members,

Dossie Solutions is looking for a new Backend Developer with Node.js and Express.js experience.

Here is the link for the job posting: https://akilconnect.org/en/talent/opportunities/696119007440b6cb768e5f5c

I treat system design like a checklist.

Here’s my go-to mental TODO list when building systems:

Fundamentals
- What are the read patterns?
- What are the write patterns?
- Who owns the source of truth?
- Is consistency or availability more critical?
- Single writer or multiple writers?

Architecture
- Synchronous or async?
- Do I need a queue, or is a cron job enough?
- Can I separate the compute from storage?
- Stateless or stateful services?
- Contracts versioned?

Reliability
- What happens when this fails?
- Where’s the retry logic, and is it idempotent?
- Are we alerting to symptoms or root causes?
- Timeouts configured?

Scaling
- How do reads scale?
- How do writes scale?
- Will this design hold up at 10x traffic?
- What’s the hot path, and how do we optimize it?

Observability
- Do we log what we need to debug in production?
- Can we trace a request across services?
- What metrics define “healthy”?
- Debuggable without redeploy?

I don’t always follow it linearly, but if something breaks or feels off, this list helps me pinpoint what I may have overlooked.

10 Most commonly asked topics in system design interviews
(not exact questions, but the ideas every interviewer is testing)

1. Design a URL shortener
Tests basics of scale, hashing, databases, caching, collisions, and tradeoffs.
They want to see how you think, not perfect answers.

2. Design a rate limiter
Very common and very practical.
Shows understanding of distributed systems, consistency, and fairness.

3. Design a cache (or caching layer)
LRU, TTL, write-through vs write-back.
Also tests eviction, memory limits, and cache invalidation thinking.

4. Design a messaging system / queue
Think Kafka, SQS, RabbitMQ style.
Ordering, durability, retries, at-least-once vs exactly-once.

5. Design a notification system
Email, SMS, push.
Fan-out, retries, idempotency, and user preferences.

6. Design a file storage system
Upload, download, metadata, large files.
Chunking, replication, CDN, and consistency tradeoffs.

7. Design a social feed
Timeline generation, fan-out on write vs read.
Hot users, ranking, and caching strategy.

8. Design a logging / metrics system
High write throughput, low latency reads.
Retention, aggregation, and cost awareness.

9. Design a real-time chat system
WebSockets, presence, message ordering.
Delivery guarantees and offline sync.

10. Design an API at scale
Auth, rate limits, pagination, versioning.
Most people fail here because they skip fundamentals.

System design interviews are about reasoning clearly under constraints.

If you understand tradeoffs and can explain them calmly, you already stand out.
