Who Am I?

I'm Pratik Pandey, a Senior Software Engineer at Booking.com, where I design and build highly scalable systems that handle millions of requests daily. With hands-on experience architecting distributed systems in production environments, I've learned that the most complex concepts become simple when explained with the right approach.

My mission is simple: Transform difficult distributed systems concepts into knowledge you can actually use to build better software.

What You'll Learn Here

This isn't your typical tech blog filled with buzzwords and surface-level explanations. Here, we dive deep into the why and how behind distributed systems patterns that power the world's most reliable applications:

🔧 Practical Implementation Guides

• Write-Ahead Logs (WAL) with real Go code examples

• Go Concurrency Patterns with examples

• DB Replication with examples

🏗️ Real-World System Design

• How companies like Kafka, Cassandra, and RocksDB solve durability

• Performance optimization techniques I use at scale

• Trade-offs between consistency, availability, and partition tolerance

• Architecture patterns

💡 From Theory to Practice

Every concept comes with:

• Working code examples

• Real system references

• Implementation considerations

• Trade-off analysis (because nothing is free in distributed systems)

My Teaching Philosophy

Start with the problem, not the solution. I believe you should understand why something exists before diving into how it works. That's why every article begins with a real challenge that distributed systems engineers face, then builds up to elegant solutions.

Show, don't just tell. You'll find code structures, realistic examples, and references to actual production systems. My goal is to give you knowledge you can immediately apply in your own projects.

Who This Is For

👨‍💻 Software Engineers

Looking to level up from building single-machine applications to designing systems that scale across data centers.

🏢 Senior Engineers & Architects

Wanting to deepen their understanding of distributed systems patterns and trade-offs.

📚 Students & Self-Learners

Seeking practical knowledge that complements academic coursework with real-world implementation details.
