Jerome Gao / Full Stack Engineer / New Zealand-based + Global Remote
I build web and cross-platform products end to end: Node.js and .NET services, API and data models, cloud delivery, and React/Next.js or React Native clients. I have also delivered production work with Python, Java, and PHP.
Professional work across backend services, enterprise platforms, investment products, commerce, and cross-platform delivery.

Full-stack contribution / Frontend Engineer
Delivered the public platform, CMS micro-frontends, shared UI packages, and a NestJS inventory service with WebSocket updates and optimistic concurrency for vehicle operations.

Full-stack contribution / Frontend Engineer

Pintec / Node.js, React, Mobile WebView, responsive web
Node.js full-stack commerce project
Built a custom commerce platform for responsive web and mobile WebView. React storefront templates served campaigns and product flows while Node.js APIs supported catalog, orders, marketing configuration, analytics, and operations reporting.
2025 / React Native, Expo, Supabase, PostgreSQL
Full Stack Engineer
Built the core board-game flow for a Te Reo Maori learning app, including rooms, realtime turns, game state, scoring, single-player and multiplayer modes, and results.
Current products where I own the backend, data, cloud, frontend, and release path. They are separated from employment work so the contribution model stays clear.
AI meal planning product with typed REST APIs, Firebase auth, resilient Gemini workflows, structured logs, Docker, Azure Container Apps, Key Vault, and Application Insights.
2026 / ASP.NET Core, GraphQL, EF Core, PostgreSQL, Next.js, Expo
Independent full-stack product
Sports community and data platform with a modular GraphQL backend, screen-shaped queries, sports ingestion, shared web/mobile clients, and a community rating model.
Cross-media rating platform with a Next.js user app, admin CMS, NestJS API, Python FastAPI admin service, shared PostgreSQL data model, tests, and CI/CD.
Node.js, NestJS and Express are the primary line, with ASP.NET Core, FastAPI, Java and PHP used where the product or existing system calls for them.
API contracts, validation, auth, schema design, transactions and migrations across PostgreSQL, MySQL and MongoDB come before client-side convenience.
React, Next.js, Vue/Nuxt and React Native turn those services into usable web and mobile products with clear state, loading, error and accessibility behaviour.
Tests, CI/CD, Docker, Azure/AWS/GCP, observability, retry and rollback thinking complete the path from repository to running product.
