Selected Projects
From marketplaces and enterprise platforms to AI assistants and tailored ERPs — and the tools and games I build on the side.
Professional Work
Design & Implementation · celebrize.de
Celebrize — Event Marketplace
A two-sided marketplace connecting people planning weddings and private celebrations with DJs, photographers, caterers, locations and more — starting in the OWL region. Providers get profiles, requests, a calendar and invoicing; celebrants get step-by-step planning, real-time availability, direct booking and verified reviews. Includes Carla, an AI agent that helps providers with their profile, services and pricing.
JUST NEXT
Design · just-next.com
In ProgressJust Next — City Events Platform
One feed for everything happening in your city — concerts, markets, sports and meetups — alongside events from your communities, favourite organizers and friends. Users subscribe to cities, join invite-only communities, follow organizer channels, RSVP and get notified before events start; venues, clubs and artists publish straight to their subscribers. Mobile apps are in soft launch, with the web app and organizer dashboard on the way.
NHD GmbH · nhd-software.com
AES/32 — Industrial Operations Platform
A modular SaaS execution layer between ERP/CMMS and the field: real-time control over contractor labor, time management, invoicing, sourcing, scaffolding and analytics for oil & gas, chemicals and energy sites. I lead the frontend team migrating the legacy monolith to microservices.
NHD GmbH · AES/32 Module
Equipment Rental Module
Manages the complete lifecycle of rented equipment — from request and multi-level approval through active tracking and maintenance to return and invoicing — with real-time visibility across every project instead of spreadsheets.
NHD GmbH · Internal AI Assistant
Holger — RAG Chatbot for Insights
A retrieval-augmented chatbot that answers questions about operational data and generates ad-hoc dashboards and reports on demand — turning manual data pulls into a short conversation that surfaces genuinely useful insights.
NHD GmbH · Internal Knowledge Base

ICON Technologies · icondirect.com / icondirect.ca

Berg Trailers · bergtrailers.net
Tailored ERP — Replacing Excel
A small ERP built from scratch for a Canadian grain- and box-trailer manufacturer, replacing a patchwork of Excel files with one shared system tailored to how the company works. Still in use today with minimal external support.
Meisterbetten GmbH · meisterbetten.de
Delivery Route Optimizer
A Travelling Salesman solver for a boxspring-bed manufacturer that delivers and assembles on site: given 7–8 destination cities, it finds the visiting order with the shortest distance or fastest travel time using real road data from the Google API.
Clariant · Germany · Internal Tool
Pipe & Box Sizing Tool
An internal engineering tool for the specialty chemicals company Clariant that determines the right pipes and boxes from a set of very complex lookup tables — turning a slow, error-prone manual lookup into a quick, reliable calculation.

Side Projects — Tools & Browser Games
Things I build on the side — a real-time multiplayer game, an AI writing tool, a small app for my kids’ school and casual games playable on desktop and mobile.
polyomino.io
Polyomino — Real-Time Multiplayer Puzzles
“Tetris gives you shapes — polyomino.io lets you build your own.” A free browser game where players collect food to grow their piece square by square, then dock it onto a shared live arena. Four modes — Tetromino (free-for-all), Pentomino (co-op picture filling), Domino (race to bridge the walls) and Triomino — plus private rooms with PIN codes, Respawn and Hardcore rules, and no account needed: just a nickname.
screenplay.loewenmedia.com

obstkalender.loewenmedia.com
Obstkalender — Fruit Rota for a Primary School
A small volunteer app for my kids’ school: parents sign up to cut fruit for the class, two per school day. Access is protected by a code from the parents’ letter, admins can block school-free days, and each week’s plan can be shared as an image straight to messaging apps. Installable on the phone.
