About me
ANALYSE.DESIGN.CODE.
13 years as a project manager in the automotive industry taught me one thing: even the best ideas fail without structure. Today I build digital systems for service businesses: website and software from one source, all connected, no tool chaos.

What clients say
I founded my practice at the start of 2026, with no technical background and a clear goal: to launch professionally from day one. Harry didn't sell me a website template, he built me a complete operating system for my practice: online shop, appointment booking with automated reminders, tax-compliant invoicing, three-level dunning automation, and payment processing via Stripe, PayPal, and SEPA: all in one platform. What other founders piece together with five separate tools runs seamlessly for me from the very first day. The time I no longer spend on admin goes directly to my clients.

VoiA is my life's project. For years I had the vision, but neither the technical know-how nor the budget to actually make it happen. Harry not only understood what I was building, he found a financial solution that worked for me, without any compromise on the result. The presence radiates exactly what I bring to my clients: clarity, quality, and trust. Since the launch, the right enquiries have been coming in from exactly the executives I want to work with.

Let's Grow Together
At an agency you explain your project to the account manager. They explain it to the project lead. They explain it to the developer. With me you say it once, directly to the person building it. Website, booking system, client management: all connected, all from one source. No pitch deck, no ticket system.
