Random Sumit.

A learning log. Things I build, things I figure out, and life outside the screen.

Projects.

A few things I have built on the side, mostly to learn how something works under the hood. Source for all of them is on GitHub.

WAL

A key-value storage engine backed by a B+ Tree and a write-ahead log for durability and crash recovery, with lock-based concurrency control; built to learn how database internals work under the hood.

QueryLens

Postgres query plan analyzer that runs EXPLAIN ANALYZE on any connected database and visualizes the plan as a tree and flame graph, with a 0–100 health score and run history to track query performance over time.
