Starting with a drawer

I’ve never been great at putting things back where they belong. Tools end up in the nearest drawer, cables get tossed in a box ‘for now,’ and small parts are scattered around the house. Everything seems fine until I actually need the 10mm socket, and then I’m turning the garage upside down while the job waits.

Every few months, when I clean out the attic, I rediscover things I forgot I owned. It’s a small, recurring reminder that how you store something decides how fast you can find it later.

I’m Sandeep. Build Log is where I work through the machinery underneath databases and distributed systems: pages, trees, transactions, storage layouts, failure modes, and the trade-offs hidden behind simple APIs.

The articles are written as practical explanations, grounded in real implementations. The current series studies BoltDB piece by piece and follows that understanding into a Rust implementation.

You can find my work on GitHub and connect with me on LinkedIn.

If you enjoy careful explanations of boring, dependable technology, you’re in the right place.
