Atelier OS
01 - Overview

Fashion houses run their business across Instagram, WhatsApp and notebooks: measurements in one place, deposits in another, a website if they are lucky.

I designed and built Atelier OS end to end, from the NestJS GraphQL API and Postgres schema to the Next.js dashboard and the storefronts that each company serves on its own subdomain or domain.

Sites are built from versioned templates that a company can edit by hand in the Studio or have generated and edited with AI, paid for with prepaid credits.

02 - What I built
A

Storefronts and Studio

Per-company sites on their own origin, with versioned templates, hand edits as an overlay, and AI template generation and editing.

B

Shop

Collections, orders, discounts, reviews, shipping, KYC and payouts, with Paystack payments.

C

Clients and commissions

Client records, measurements and bespoke projects, with appointments and booking links.

D

Client portal and referrals

A magic-link portal where clients follow their commissions, plus a referral contest with a leaderboard.

E

Growth tools

Blog, marketing campaigns, runway showcases, team members and billing.
