Shopify apps that do one job properly.

I'm Philip Biedermann. I build and maintain my own Shopify apps, two of them live on the App Store, and I take on custom app and theme work for merchants who have outgrown their theme settings.

Live on the Shopify App Store

Both started as a recurring chore in a real store. Each has a free plan, so you can install it and see whether it fits before paying anything.

Live

Breadcrumbs Pro

Clear navigation trails for shoppers and for search engines, styled in a live preview, without touching theme code.

In development

Store links appear once a listing is approved.

  • Sticky Add to Cart BarConversion

    Keeps Add to Cart in reach while shoppers scroll, with free-shipping progress, countdown and low-stock notes.

  • Mix & Match Bundle BuilderMerchandising

    Customers build their own set; volume tiers as percentage, amount or fixed set price.

  • Wholesale HubB2B

    Trade-account sign-up with an approval queue, VAT ID capture and CSV quick ordering.

  • EU Widerruf ProCompliance

    A guided right-of-withdrawal flow in the storefront, aware of §312g exceptions, with dashboard and CSV export.

  • Prices & SalesPricing

    Scheduled price changes with charm rounding, cost guards and a dry run before anything goes live.

  • Shop-LOCKAccess control

    Lock pages, products or prices behind passwords, customer tags, age checks or region rules.

  • WaitlyInventory

    Pre-orders and back-in-stock alerts, so sold out becomes a waiting list instead of a lost sale.

Custom work for your store

Fixed scope or ongoing. You get the code, the repository and a handover note, so nothing depends on me afterwards.

Custom Shopify apps

Embedded admin apps, theme app extensions, app proxies and webhooks, built to the same standard that got two of my own apps through App Store review.

OAuth · GDPR webhooks · Billing API

Storefront and theme engineering

Sections, mega menus and conversion widgets written into the theme you already run, editable in the theme editor so your team can change copy without me.

Liquid · Web Components · Section schema

Data and automations

Order and returns pipelines, catalog jobs and internal dashboards. The plumbing that takes a recurring manual task off someone's Monday.

Admin GraphQL · Bulk operations · Scheduled jobs

Retention and e-mail

Klaviyo flows, templates and sign-up forms wired to real store events, so the second purchase has a trigger behind it.

Klaviyo · Event tracking · Templates

  1. Scope in writing

    One page: the problem, what the change does and what it doesn't. A fixed price attaches to that page.

  2. Build on a dev store

    Your live storefront stays untouched until you've seen the thing working.

  3. Review before deploy

    A preview link and a short walkthrough. Changes to prices, stock or customer data run as a dry run first.

  4. Hand over, then support

    Repository, settings and a README your next developer can read, plus a support window afterwards.

The person who writes the code is the person you talk to.

I build Shopify software: my own apps, and custom work for merchants who hit the edge of what themes and off-the-shelf apps can do. Every project starts as a real problem in a real store and gets built to solve exactly that.

The apps above came out of the same practice: jobs that came up often enough to be worth turning into a product. Nothing is marked live here until its listing is actually published.

Either way you get readable code, a repository you own, and a straight answer about cost before work starts.

Got a store problem that needs code?

Describe it in a few lines. You'll get an honest answer on scope, cost and whether it's worth building at all. No intake form, no discovery call.
