A deterministic TypeScript document room for validating order input, calculating totals, assigning stable invoice numbers, and writing compact PDF bytes.
Production-oriented Node.js custodial wallet backend with MFA, withdrawal approval controls, tamper-evident audit events, PostgreSQL and Redis integration, and a replaceable custody-provider adapter.
A drop-in Stripe Checkout integration plugin for TypeScript backends, designed to connect with a Commerce Backend Block via a `CommercePaymentAdapter` interface. It handles the full payment lifecycle — session creation, webhook signature verification, event normalization, and refunds — while deliberately owning nothing outside Stripe: no products, orders, cart, or stock tables. Built for developers wiring Stripe test-mode payments into a commerce SaaS, with Express routes, typed contracts, and a security-hardened raw-body webhook endpoint included under the Tetrees License.

A TypeScript plugin that accepts fashion or reference images and returns a structured `VisualStyleAnalysis` JSON object — covering style tags, color palette, fit direction, formality, and occasion signals — by routing requests through a swappable multimodal AI provider (Claude, GPT-4o, or Gemini) via a unified `VisionProvider` interface. Exposes six callable functions plus an Express HTTP API, with a deterministic mock mode for credential-free testing and a built-in normalizer that handles off-contract provider responses. Designed for personalized commerce backends that need a clean image-in → structured-style-data-out boundary, with explicit safety constraints that prevent identity inference, biometric analysis, or sensitive attribute extraction. Licensed under the Tetrees License.
4.8 (28)
A SQLite database schema and WAL (write-ahead log) artifact for an AI-powered product recommendation engine, storing cached products with style, occasion, color, and size tags alongside user style profiles and persisted recommendation sets with line items. Includes a feedback table for capturing user responses to recommendations, with indexed queries optimized for per-user history retrieval. Built for TypeScript backend developers integrating personalized shopping or catalog recommendation features into their applications, licensed under the Tetrees License.
4.8 (24)
A self-contained TypeScript/Express commerce backend covering the full shopping lifecycle — product catalog with variants and tags, cart management, atomic checkout with stock gating, order creation, and payment records stored in SQLite via `better-sqlite3`. Designed for AI outfit commerce demos, it exposes 25 pure service functions that can be called directly in-process or consumed over HTTP by frontend, recommendation, and payment blocks. Ships with 67 passing integration tests, 12 seeded demo products, and a clear extension point for swapping in a real payment provider via `payment_provider` and `provider_payment_id` columns.
4.7 (21)
A TypeScript/Express backend block that handles the full identity and personalization pipeline for AI-driven SaaS apps: JWT-based auth with hashed session tokens, user profiles with onboarding completion tracking, media metadata storage, intake questionnaire upserts, and deterministic style-profile generation from preferences and answers. Built on SQLite via `better-sqlite3` with an idempotent schema, it exposes clean REST endpoints under `/api/users/me` and `/api/admin`, and accepts enrichment from an external AI Vision Plugin via a dedicated `/style-profile/visual-analysis` endpoint without taking any direct AI provider dependency itself. Licensed under the Tetrees License.
4.8 (19)
TypeScript React e-commerce frontend with Vite, React Router, and Tailwind CSS.

Express backend API for OpenAI chat completions with two configurable model slots (GPT-5.3 and GPT-5.4).

Includes health checks, model introspection endpoints, and structured error handling. Built in TypeScript with CORS support and environment-based configuration.
