Hands On System Design with Distributed Systems Implementation

What you'll build

LogStream

a production-grade distributed log platform, built lesson by lesson across roughly a year

The curriculum

4 core areas covered
01 System decomposition and scalable backend design
02 Database optimization, API design, and caching strategies
03 Load balancing, security, and performance optimization
04 Monitoring and observability for distributed systems

What you'll walk away with

LogStream β€” a real distributed log platform, not a diagram of one
The gap closed between "I can whiteboard it" and "I can run it in production"
254 concrete deliverables to point to, not one abstract capstone

What you're signing up for

What makes it different

"Build real components with tangible outputs every single day" β€” a production mindset covering security, scalability, observability, and fault tolerance.

Format

Bite-sized daily lessons, free via Substack, progressing from basics to complex architecture over roughly a year. Practical coding tasks in Java/Spring Boot (principles are language-agnostic).

Who it's for

Engineers who can pass a system design interview on a whiteboard but have never actually built the distributed system they were describing.
