Shopify Apps · Custom Sections · Tools

When off-the-shelf apps stop being enough: custom-built Shopify tools.

Custom sections, embedded apps and standalone tools. For stores that need more than what the app store has to offer.

Diagnosis

Off-the-shelf apps hit limits.
That is exactly where my work starts.

The standard app does 80% of what you need. The decisive 20% is missing.
What it costs you
You pay monthly for a tool that does not cover your most important use case.

Off-the-shelf apps are a compromise. Custom tools are an investment.

Custom-built means exactly what your store needs. No more, no less.

Services

What I build.

Shopify Custom Sections

Sections that match your campaign, not the standard theme.

Shopify Apps (embedded & standalone)

From the idea to the App Store launch. Embedded in your admin or as a standalone app.

Custom Backend Tools & Portals

Dashboards, internal tools and customer portals that map your processes.

Integrations & Data Pipelines

Your tools talk to each other. Automated, instead of CSV by hand.

Approach

From the idea to the finished tool.

No feature bloat. Clear scope, early deploys, a tool that actually gets used.

01Discovery

Unclear scope eats budget.

My partI first clarify what your store actually needs.

02Scope

Feature bloat costs months.

My partMVP scope instead of all at once.

03Build

Months without visible progress.

My partIterative, with deploys from week 1.

04Launch

Tools that never go live.

My partApp Store process or a clean integration into your store.

Frequently asked

Before you ask.

Both. Sometimes it is a single section for a campaign, sometimes a complete app. We start with what helps you most right now and build out from there.
Then that is exactly where we start. In the intro call we work out where your store struggles and what pays off fastest. A rough problem turns into a clear, doable scope.
Yes. I build so that you or your team can keep working on it later. Clean code, short docs and a handover if you want. No vendor lock-in.
Yes. I get into existing themes and codebases and build on top of them instead of rebuilding everything. Where it makes sense, I tidy up along the way.
Depending on the project, as a fixed price for clearly scoped builds or on a day-rate basis for ongoing work. You get a transparent estimate up front, no hidden costs.
