Why custom
Custom pricing rules, product builders, order workflows and checkout behaviour, written for your business instead of bolted on through three apps.
I built a custom checkout app that integrates Square payments for Genix Flooring. Payment logic is the work other developers avoid.
Sync with your ERP, CRM, 3PL or spreadsheets through the GraphQL Admin API and webhooks, so data stops being copied by hand.
Admin apps, theme app extensions and background jobs built on the GraphQL Admin API. If an app does not exist for what you need, or three apps are doing the job of one, I will build the one.
Payment gateway integrations, checkout customization with Functions and checkout extensibility, and Plus-specific requirements. Payment code gets extra care: test mode first, then staged rollout.
When you need a fully custom storefront, I build with Hydrogen and the Storefront API. I will also tell you plainly when a well-built theme would serve you better and cost less.
ERP, 3PL, CRM, accounting and spreadsheet integrations through webhooks and the Admin API, with retries and logging so a failed sync is visible instead of silent.
The stack
Scoped before it's built
Custom apps vary a lot, so I review the requirements first and tell you plainly if a spec won't hold up technically. Work happens on a development store and staging, in Git, with a handoff note on every task.
Tell me what you need. You get an honest estimate after a read-only look at your store, and you pay nothing for the conversation.
