I’m a TypeScript and React Native engineer focused on offline-first architecture, clean abstractions, and reusable developer tooling.

I’m the creator and maintainer of MelonDB — an open-source, AST-first local database stack for React Native with SQLite adapters, reactive queries, optional Watermelon-compatible sync, and a migration path for teams that care about performance, clarity, and long-term maintainability.

I like building systems that stay honest under pressure:

• one internal query representation instead of three drifting execution paths
• storage and sync as separate products, not one tangled package
• React Native support that works in Expo Go and has a native performance path for dev builds
• docs, ADRs, and release engineering treated as part of the product

• Building and publishing the MelonDB package ecosystem
• Offline-first sync architecture and local-first DX
• React Native, TypeScript, SQLite, and reusable package design

• MelonDB — offline-first database tooling for React Native + TypeScript
• Melon-DB Docs: melon-db-docs
• GitHub: nwnichols02/melon-db

I write about architecture, offline-first systems, and the tradeoffs behind building real software:

• Portfolio: nathan-nichols.vercel.app

I care a lot about software that is composable, explainable, and built to last.
