Rails & Spree pods — e-commerce & marketplace scale

Ruby on Rails and Spree Commerce power our high-performance commerce pods — for brands that have outgrown Shopify and need custom marketplace infrastructure. Governed delivery with sober release discipline, the Transparent 15% Model, and 100% IP transfer (Work for Hire).

Where Rails / Spree fits

Rails and Spree are our stack for e-commerce and marketplace scale — when your differentiation is catalogue depth, fulfilment logic, or integrations, not reinventing cart code. High-performance commerce pods for operators who need more than a template storefront.

New store vs operating a live Spree

Greenfield commerce work funds catalogue modelling, payment flows, refunds, tax handling hooks, and operational reporting — the first production release is more expensive than “just an MVP UI.” Live operations shift spend to steady improvements: conversion fixes, partner integrations, performance, and fraud edge cases.

Engineering Leadership & Quality Standards

Every Rails pod ships with peer review cycles, CI/CD enforcement, and senior architectural oversight as baseline — not optional add-ons. Seniors own data modelling, security, and payment boundaries; mids drive feature throughput; juniors work on well-specified UI and test slices under review. AI-assisted catalogue ingestion still requires senior technical leadership for quality and cost control.

Representative delivery (on-page)

AI‑powered store builder

Spree + Rails — scraping/catalogue import guided by prompts, product generation, background jobs (Sidekiq-style patterns), operator workflows.

  • Import pipelines and error handling
  • Store generation with sensible defaults

Rails APIs & admin

Multi-tenant or B2B workflows where conventions speed delivery — with explicit boundaries for permissions and billing.

Cost expectations

Milestones are quoted after discovery — pricing. Dedicated pods follow monthly GBP team economics under the Transparent 15% model — see role bands. Commerce programmes vary widely: a focused integration milestone is scoped tightly, while a multi-release marketplace roadmap is typically phased into several milestones tied to releases — we document assumptions before engineering starts.
