Brand website and membership platform for the China market: integrates product discovery, e-commerce referral, member points and skin profiles into one experience, unifies WeChat / Douyin / phone-number identities, and supports online retail and repurchase from 0 to 1; 205 API routes / 51 models / 2,100+ tests.

  • Brand Website & Member Platform: Built the brand's official website and member platform with Next.js 16 + Prisma + PostgreSQL — product showcases, third-party e-commerce referral (Tmall / Douyin / Xiaohongshu / WeChat Shop links + GA event tracking), membership tiers, points ledger, points redemption (SF Express tracking), consumption backfill, skin profiles, and a security center; aggregated WeChat, Douyin, and phone OTP identities into a unified account system — 205 API routes, 51 data models, and 2,100+ automated test cases.
  • Product & Interaction Design: Independently designed the information architecture, Figma interactive prototypes, and visual styling; built multi-step skincare ritual guides and immersive brand storytelling with Framer Motion + View Transitions, integrated the product drawer with detail pages, and delivered fully responsive layouts.
  • Admin Console & Security Governance: Built an admin console covering products / categories / members / points redemption / consumption backfill / jobs / messages / OAuth clients (Tiptap rich text), with TOTP two-factor authentication and step-up verification for sensitive actions, operation audit logs and daily integrity anchors, scheduled jobs, database-persisted rate limiting, and webhook failure retries; completed SEO / GEO (sitemap / JSON-LD / llms.txt / Baidu push).

Jul 2026 – Present
Product & full-stack development: independent

Unified identity foundation for Greater China: a self-built OAuth 2.0 / OIDC single sign-on that connects the website, skin-analysis site, two mini-programs and admin console, and enables cross-domain login and global logout across 5 systems, with TOTP 2FA on the admin console, packaged as a reusable npm SDK.

  • Protocol Implementation: Built a self-hosted OAuth 2.0 / OIDC SSO, deployed isomorphically with the official main site, which acts as the Authorization Server issuing RS256 JWTs — fully implementing the authorize / token / userinfo / introspect / revoke / end-session protocol endpoints with support for PKCE and DPoP; the admin console is protected by TOTP two-factor authentication.
  • SDK & Integration: Packaged and published npm SDKs (@nihplod/sso-sdk / @nihplod/sso-verify) for minute-level sub-project integration, enabling cross-domain SSO and global sign-out via Token Introspection + Backchannel Logout, supporting unified login across the official website, skin-analysis site, both WeChat mini-programs, and the admin console.
  • Security Hardening: Supports secret rotation, token revocation (RFC 7009), and multi-instance blacklist sharing for an operable and auditable auth system.

Jan 2026 – Present
Product, interaction & full-stack development: independent Visual design in collaboration smart.nihplod.cn

AI skincare advisor for consumers: dual-channel skin analysis via questionnaire + face scan, personalized product recommendations based on skin type, season and region, with reports and profiles passed to WeCom advisors — closing the loop from analysis to regimen, follow-up and repurchase; 93 API routes / 531 tests.

  • AI Skin Analysis & Personalized Recommendations: Integrated Tongyi Qianwen VL / DeepSeek LLMs for dual-channel (questionnaire + facial scan) skin analysis; a custom rule engine scores and matches products against 8 skin-type personas plus seasonal / regional environmental factors, configurable through a visual admin console (zero-code adjustments for operations).
  • Conversion & Attribution: Led model integration and core API development; e-commerce outbound links (Tmall / Douyin / Xiaohongshu / WeChat Shop) support UTM / pid tracking and click-event instrumentation, forming an attributable consultation-to-conversion path together with WeCom advisor short links.
  • Growth & Membership Operations: Connected four-tier member skin-analysis quotas (Standard 10 lifetime sessions; Silver 10 + 20 per ¥1,000 spent, max 10/day; Gold / Diamond unlimited total, max 10/day), with reports and profiles tied to the logged-in account; designed share posters, channel ref attribution, and registration-conversion popups, and exported desensitized aggregate CSV statistics to feed the brand whitepaper and market insights.
  • AI Cost & Reliability Engineering: Designed an AI request queue with concurrency control, circuit breakers, daily / monthly token and cost budget cutoffs, persisted per-call billing, and a model whitelist with provider fallback; used idempotent retries and quota reservation / release to prevent duplicate charges; current skin profiles carry a rolling 90-day validity for retest prompts, full reports are retained for 365 days, and hot / cold tiered archiving keeps the latest 10 full reports plus desensitized cold-tier summaries for up to 3 years.
  • Data Asset Loop: Designed a server-to-server API with HMAC signatures + IP rate limiting; skin-analysis reports and skincare profiles pass through to WeCom AI customer service via session_id, turning one-off skin tests into continuously operable, repurchase-driving user data assets.
