Services

Systems work for ecommerce teams that have outgrown plug-and-play.

We take on the hard, load-bearing parts of an ecommerce stack: the subscription engine, the data pipeline, the search layer, the bespoke Admin UI. If it has to be reliable, it's probably something we build.

Shopify apps

Embedded and standalone Shopify apps — built on the Admin GraphQL API, with Token Exchange auth, Managed Installation, and the full Shopify extension surface area. Billing, webhooks, theme app extensions, Checkout UI extensions, Web Pixel extensions, Functions.

Admin UI in Go templ + HTMX + App Bridge — fast to ship, easy to maintain, and we reach for React or Next.js when a project needs it
Token Exchange + Managed Installation (the 2025 Shopify auth flow)
Billing API, webhook HMAC verification, GDPR mandatory webhooks
Theme app extensions, Checkout UI extensions, Web Pixels, Functions

Event pipelines

First-party server-side event tracking for Shopify brands that care about ad ROAS and attribution. Events flow from the Shopify Web Pixel through a durable queue to every destination you care about.

Append-only event store with replay from any destination credential rotation
Per-destination transformation (CAPI, TikTok, GA4, Klaviyo, Pinterest, Snap, Segment, webhooks)
Dedup on event_id across browser and server paths
Retry on 5xx with exponential backoff + dead-letter queue

Custom tooling

The things that don't fit anywhere else. Catalog enrichment, filter trees for large catalogs, bespoke merchandising dashboards, fulfillment glue code, subscription state machines, internal ops tooling. Anything that a no-code tool does badly, we do well.

Go backends, Postgres, Redis, Meilisearch — boring tech on purpose
Runs on infrastructure you own (we help set it up)
Readable source that your team can keep maintaining after we leave
