Tom Sailors — independent Shopify Plus developer.
One developer, working directly with mid-market merchants ($1M–$50M GMV) on the integrations and custom apps that off-the-shelf Shopify apps cannot model. No agency layer, no account managers, no sales team.
The role
Tom Sailors is a Shopify Plus Developer and Shopify App Developer — independent, solo, code-only. He works exclusively on Shopify and Shopify Plus. The center of the practice is custom Shopify apps and the integrations most mid-market stores ride on once SaaS limits start to bind: B2B portals with contract pricing, native Subscriptions migrations off Recharge or Bold, Shopify Functions (Discount, Delivery, Cart Transform, Payment, Order Routing), ShipEngine multi-carrier shipping, Apple Wallet pass programs, custom loyalty engines past the SaaS ceiling, Amazon Connect call-center integration, and AI agent-readiness work that gets a Shopify catalog cited by ChatGPT, Claude, Perplexity, and AI Overviews.
Tom does not do theme design, branding, marketing strategy, paid ads, email campaign building, SEO consulting, or anything outside Shopify. He writes the code; he refers everything else to specialists.
How engagements work
The default is a build-scoped engagement, not hourly. A brief describes the problem; a quote covers the build; the work happens directly between Tom and the merchant's team. No project manager, no account manager, no sales handoff. The same person who scopes the work writes the code.
Every public brief and case study on this site carries runnable code validated against Shopify's live GraphQL schema at publish time — the work is real, the proof is on the page.
