System Design Roadmap System design interviews can be intimidating, especially when you're faced with designing systems that handle millions of requests per minute.

But with the right approach and understanding of core concepts, you can navigate these interviews confidently.

🚀 New tutorial: Build your first MCP server in Python!

If you've wondered how AI assistants connect to real tools and data, this one is for you. No experience with MCP needed. We start with simple diagrams, then build a working server step by step: 2 tools, 1 resource and 1 prompt, tested and connected to an AI app.

Stop getting stuck on AI theory. If you want to stand out as an engineer right now, you need to know how to build and deploy real, production-ready AI systems.

At Systemdr, we just dropped a massive deep dive into how modern AI infrastructure is actually architected. We aren't just talking about high-level concepts—we are building scalable retrieval pipelines, fine-tuning models, and deploying infrastructure that can handle real-world scale.

Your like button shouldn’t wait for your analytics pipeline. 🧵

In a classic request-response app, when Sarah likes a post the server does everything in a single request:
→ update the counter
→ notify followers
→ refresh recommendations
→ log analytics

The slowest step decides how long Sarah waits. That’s why like buttons freeze and timelines lag exactly when a post goes viral.

Event-driven architecture flips it:
✅ Publish ONE content_like event to Kafka
✅ Respond to the user instantly
✅ Let analytics, notifications and recommendations each consume it independently and in parallel

In Day 1 of Hands On Kafka we build StreamSocial, a working event-driven social platform:
🔹 A 10-event taxonomy (user actions, content interactions, system events)
🔹 A Kafka producer and consumer in Python
🔹 A FastAPI backend
🔹 A live React dashboard
🔹 A test suite

It’s the same pattern behind Netflix, Uber and Slack: one event, many independent reactions.

Ever heard of a Forward Deployed Engineer? Most engineers haven't, yet it's one of the best-paid AI roles of 2026 ($300K–$785K total comp).

I went through 22 real job postings and found the same 5 skills in every one. Then I built a hands-on, 35-week course to teach exactly those skills, with tested code you run yourself.

Most Kafka courses stop at producers and consumers. This one keeps going for 60 days. 🚀

6 modules, 10 days each, and one system you build yourself: StreamSocial, in Java and Spring Boot.

Save this roadmap and start with Day 1. Link in bio.
