Things I've built

// npm package. Kenyan administrative data.

A TypeScript library providing structured data for all Kenyan administrative divisions including all 47 counties, constituencies, wards, localities and areas. Supports fast O(1) lookups by code or name, hierarchical queries and case-insensitive search. Used in production in a real estate marketplace and a sales ERP for location-based record keeping.

// Relational database engine. Built from scratch.

Curiosity project: I wanted to understand what actually happens inside a database how rows get stored, how an index turns an O(n) scan into an O(1) lookup, how a SQL string becomes an executed operation. So I built one. MyRDBMS is a relational database engine with in-memory storage, file persistence, a SQL parser, B-tree-style indexing and support for multi-table joins. Comes with a Next.js query console, a REST API and an interactive REPL so you can poke at it from any angle.
