nstop is an iOS app that delivers real-time departures, platform changes, and service alerts from every transit operator in the Netherlands — entirely in English. It’s the first product from NSTOP LTD, the company I founded to fix how expats navigate Dutch public transport.

The problem

Every Dutch transit app assumes you speak Dutch. The existing alternatives are slow, ad-riddled, or don’t cover all operators. nstop is built from scratch for people who live in the Netherlands but don’t speak the language — a market of roughly 1.6 million people that no one is serving well.

Architecture

• Live data from the national NDOV gateway, covering all major operators (NS, GVB, RET, HTM, Arriva, and more)
• SwiftUI interface with zero external dependencies
• Upcoming: calendar integration that tells you when to leave, not just what’s departing

BasketWise aggregates live promotions from every major Dutch supermarket and helps you build shopping lists that automatically find the cheapest store for each item — including split-trip optimisation across up to three stores.

Built for the same expat audience as nstop: English by default, because every existing Dutch grocery deal app assumes you speak the language.

How it works

• Automated scrapers pull promotions daily from seven supermarket chains via APIs, structured page data, and fallback actors
• Smart shopping lists match your items to active deals with confidence-scored recommendations
• Split-trip optimiser calculates the cheapest combination of stores for your weekly shop
• Price history tracking with EU Omnibus Directive compliance for honest discount detection

Rattie is a SwiftUI app built for — and winner of — Apple’s Swift Student Challenge 2026. I built it because I have eight pet rats and couldn’t find a decent health tracker for them — so I made one in a weekend and it won an award.

It manages the full health record of a mischief of pet rats, with a unified timeline, auto-generated care checklists, and Squeaks — an on-device AI assistant powered by Apple’s Foundation Models framework.

All data stays on-device. No account required. No tracking.

Schedyx is a homelab-first scheduling tool for people who want Reclaim or Motion’s intelligence without the subscription or the cloud dependency.

Runs as a Docker Compose stack. Connects to Google Calendar (and CalDAV for iCloud/Nextcloud). Auto-schedules tasks, habits, and focus blocks around your real calendar — with configurable scheduling modes from burnout-aware to deep work.

Running a private cloud at home because renting someone else’s is fine until it isn’t. Four Proxmox nodes form the compute backbone — VMs and LXC containers for everything from isolated dev environments to persistent production-like services.

What’s running:

• Email — Mailcow-dockerized stack as a secondary mail system alongside Microsoft 365. Full SMTP/IMAP, spam filtering, DKIM/DMARC, webmail.
• Identity — ZITADEL as a self-hosted OAuth 2.0 / OIDC provider. SSO for internal apps without depending on a third-party IdP.
• Networking — Pangolin reverse proxy exposing selected private services to the internet with proper TLS, without punching holes in the firewall.
• Media & storage — NAS stack with media server applications for local streaming and file management.
• Dev environments — Isolated VMs and containers for testing infrastructure changes and building projects like nstop and SchedyX without touching anything production-adjacent.

The goal isn’t to replicate cloud providers — it’s to understand at a low level what they’re doing, own the data, and build systems I actually trust.
