Shopify · Authentication

Her-age NFTIZE — luxury authentication and a digital passport, mapped SKU to TokenID, on the current Shopify API.

NFTIZE is Her-age's internal Shopify app: authenticate a luxury item, then issue a digital passport — an NFT certificate after expertise. SKU / VariantID maps to TokenID. Manual and batch. We migrated it to the current Shopify API (GraphQL, session tokens), redesigned DynamoDB PK / SK / GSI, gave experts Next.js status tracks, put an audit trail and queues with a DLQ under the jobs, and cleaned AWS. Work restored. Server ops cost −30%.

A passport, not a mint dashboard

After expertise, the item gets a digital passport: an NFT certificate. The operational problem is the map — SKU / VariantID ↔ TokenID — in one-off and in batch. We do not publish mint counts or chain metrics. The job was to make the map and the statuses true again.

API, store, then the expert's track

Migrated to the current Shopify API: GraphQL, session tokens. DynamoDB keys redesigned — PK, SK, GSI — so lookups stop lying. Next.js status tracks for experts. Audit trail on the work. Queues and a dead-letter queue so a failed batch does not vanish. AWS: S3 lifecycle, services consolidated, the bill smaller.

  • Shopify GraphQL and session tokens
  • SKU / VariantID ↔ TokenID, manual and batch
  • DynamoDB PK / SK / GSI redesign
  • Expert status tracks on Next.js
  • Audit trail, queues, DLQ; S3 lifecycle and service consolidation

Sibling of Sell with Us, not the store

This is the authentication app. The consignment app is her-age-sell-with-us. The store redesign is her-age. Three products, three cases. NFTIZE: restored work, new API, −30% on server ops.

TypeScript, Postgres and edge deployment are not exciting — they are how you still iterate fast in year three without rewriting the platform.

Luxury · Volume eDTL

The Brand Collector

The Brand Collector resells pre-owned luxury through a supplier network. Same class of problem as a catalogue feed — except each dump crossed 120,000 rows, and the CSV they hold sits above 169,000. Fastify stayed the orchestrator. The heavy compute moved to Go workers. About 60% faster on taxonomy, mapping and pattern-match at that volume.

Under NDA we stabilised three production gambling brands: cleaned up legacy PHP/JS stacks, extracted shared modules, and shipped a new marketing site without stopping live traffic.

Digital DAO

Digital DAO is a marketing studio in Belarus that works mostly with fintech. We did not repaint the old site. We rebuilt the story and the visual system so it would sit in a room with banks, not with a carnival agency deck.
