nayokids
A curated kids-fashion platform that remembers every child — and grows with them.
NAYO is a curated own-brand children's store selling both individual pieces and complete, beautifully-boxed outfits. Under a quiet, editorial storefront sits a full commerce engine: a real-time inventory ledger, a personalization layer that learns each child, a machine-learning service, and a Seller Central the owner runs the whole business from — built for the Israeli market, top to bottom.
It remembers every child.
Each family gets a store that learns. From real purchase and wishlist history it builds a style profile, recommends what fits the child's taste, and runs Size Watch — the outgrow predictor that quietly tracks each child up the size ladder and flags the next size before the current one stops fitting. It's the highest-intent moment in kidswear, turned into software.
A warehouse that can't lie.
Pieces and outfits draw from one shared stock pool, so an outfit's availability is only ever the minimum across its parts — computed live, never cached. Every movement is written to an immutable ledger, and checkout reserves stock so two parents can't buy the last one. "Only 2 left" is a fact, not a guess — which, under Israeli truthful-scarcity law, is exactly what it has to be.
The owner runs everything.
A full back office, not a plugin. Revenue, funnel and margin at a glance; an outfit composer with live cost roll-up; theme studio, orders, reviews, coupons, tiers and consented analytics that feed the recommendation engine. Everything the owner needs to merchandise, price and restock — from morning coffee, on a phone.
Many moving parts, one system.
A typed codebase end to end, a pure pricing core, a separate ML service that can fail without touching checkout, and a data layer built to scale from the live app to full production.

Live today on a Node + React build with the immutable ledger, pricing engine, loyalty, heuristic recommendations and consent-gated analytics running in production — engineered to scale to the Next.js SSR + PostgreSQL + Redis + Meilisearch + FastAPI architecture below.
Money and children's data get real protection. Payments run through a hosted, PCI-compliant provider so card details never touch the server; sign-in uses scrypt-hashed passwords; and the whole store is built to Israeli law — truthful scarcity, opt-in marketing, and PPL Amendment 13-aware consent.
