Netherlands / full-stack software developer

LarsNieuwenhuis

I build practical web systems: admin flows, product-backed interfaces, QR workflows, dashboards, and the small details that make software less annoying to use.

Comfort zone: React, TypeScript, Laravel, Vue, GraphQL
Learning edge: Axum, SQLx, deployment-grade Rust

About

I like making tools feel obvious.

I like taking a workflow apart until the state, permissions, and next action feel obvious. The best projects are the ones where people stop thinking about the interface and can just get on with the work.

Most of my work so far sits around React, TypeScript, Laravel, Vue, and GraphQL. This portfolio is where I'm trying Rust in public: Axum for the server, Askama for templates, SQLx for the database, and PostgreSQL behind it.
