Hey, I’m Abhay

I’m a Principal Software Engineer who has spent years designing and operating distributed systems at scale. This blog exists because I couldn’t find a single place that explained system design clearly — most resources are either too shallow for engineers or too academic for practitioners.

Every post here is written to bridge that gap: real concepts, explained from first principles, with enough depth that you can actually apply them.

What This Blog Covers

System design is broad. Here’s what I focus on:

  • Scaling fundamentals — how systems grow from a single server to millions of users
  • Database patterns — replication, sharding, caching, and when to reach for NoSQL
  • Infrastructure building blocks — load balancers, CDNs, message queues, and rate limiters
  • Real-world case studies — how companies like Netflix, Twitter, and Uber solve hard problems
  • Interview preparation — structured approaches to system design interview questions
