Nanzero Interactive
Software for sport and the web
Nanzero is Norman van der Ploeg — a one-engineer practice. I design and build the whole stack, from native and cross-platform mobile apps to Go services and web front ends, for teams who need software that holds up in the field.

Capabilities
Fourteen years of shipping production software
Mobile
Native iOS in Swift and Objective-C against UIKit and SwiftUI, and cross-platform apps in Flutter. Mobile since 2012 — four years building the analytics and ad SDKs that ship inside other developers’ apps, then four years at Avenza leading the iOS team on an app with millions of downloads. Now Skadi’s Edge, live on Google Play and in TestFlight beta on iOS.
Backend & cloud
Go REST APIs behind an NGINX reverse proxy, each service containerised with Docker on a Linux VPS with no public ports but the proxy and SSH locked to key-only auth, with Firebase Auth for identity, Firestore behind Skadi’s Edge and PostgreSQL behind Skadi Events, and Stripe — subscriptions, Connect and webhooks — handling money. Earlier: Go services on Cloud Run with BigQuery, and C# backends under gaming regulation.
Web
Svelte and SvelteKit dashboards in TypeScript, working against the same typed data model as the mobile clients, and React front ends — including one that ships inside an existing CMS as a WordPress plugin, isolated in a shadow root so it and the host theme leave each other alone.
Engineering practice
Technical leadership and code review — led four iOS developers and raised test coverage from 6% to 35% at Avenza. Everything ships through a pipeline: Git workflows, automated builds, containerised deploys. Plus AI-accelerated and agentic development workflows in day-to-day delivery.
Availability
Open to senior engineering roles and select client work.
