About

Not an agency.
But real shop-floor experience.

I'm Jonas, 40. For fifteen years I ran two jewellery shops and a webshop — at its peak, a team of twenty colleagues.

I know the chaos of failing systems, stock that doesn't add up, and agencies selling you a trick without understanding how your business actually runs. That's why I switched to Shopify and taught myself to code.

Today I'm the builder who stands next to you in the shop, not the consultant giving advice from the sidelines. Shopify is my centre of gravity, but the right solution is sometimes a quiet website or an app that doesn't exist yet. I build what fits. Large, hands-on projects — involving hardware, a till, or on-site work — get my full focus, one at a time; smaller websites run smoothly alongside each other.

— Jonas Smets

Services

One point of contact,
from strategy to code.

01

Shopify.

My home ground. Migration from your old system, development, Shopify POS on the shop floor, and the entire app ecosystem — marketing, reviews, loyalty — tuned together.

02

Web development.

Not every story needs Shopify. A quick one-pager, a blog, or a bespoke site in Next.js, WordPress or Ghost — always the right tool for the story, not the other way round.

03

Custom apps & bespoke.

Have a workflow that doesn't exist off-the-shelf? Then I build the app that adapts to your business. RepairManager, Sendcloud Connector and CreditClub all grew out of real shops.

04

Strategy & guidance.

One client at a time. I come on-site to think through growth, processes and tech with you — and train your team so everything runs independently after the project.
