Project details
You get a real production AI feature built into your existing React and Node.js app, not a demo that breaks under load. I scope the feature, build the layer with the OpenAI API or LangChain, add a vector database for semantic search where it helps, and wire the API and React UI so your users can actually use it. Backed by a decade of full stack work and a 100% Job Success Score across 84 Upwork contracts. The result is an AI feature that ships to production and that your team can extend after handoff.

I build the whole thing. React and Next.js front ends, Node.js and Express back ends, and the AI features that live inside them. As a full stack developer with real AI integration depth, I own the full stack build, from the React UI and the Node.js API to the data layer and deployment. One full stack developer accountable for the whole system, not a single layer of it.

WHAT I BUILD AS A FULL STACK DEVELOPER
▸ Full Stack Web Applications
React and Next.js front end, Node.js and Express back end, MongoDB or PostgreSQL data, REST or GraphQL API. The complete full stack build owned by one full stack developer, documented and handoff-ready so your team can maintain it.
▸ AI Integration and Chatbots
OpenAI API and LangChain orchestration, RAG pipelines over your own data, vector databases for semantic search, and chatbots wired into your full stack app. AI built by a full stack developer as a production layer, not a prototype that breaks under load.
▸ Full Stack SaaS and Platform Development
Multi-tenant data design, subscription and billing flows, and role-based dashboards. Full stack developer work that holds up in fintech, insurance, and healthcare, where data integrity and access control are not optional.
▸ Node.js APIs and Integrations
REST and GraphQL APIs, authentication and role-based access, webhooks, and integrations into your CRM, ERP, and existing tools. As a full stack developer I design the Node.js API around the React front-end data needs first, so the full stack seam never becomes the part that breaks.
▸ Codebase Rescue and Maintenance
Reading an existing React and Node.js codebase fast, untangling tangled state and API mismatches, and shipping the next feature without breaking what works. This full stack developer work is how many of my long-running Upwork contracts started.
SELECTED WORK
▸ Commercial Insurance Agency Platform
Online agency system with multi-role access and policy workflows, built as a full stack developer in React and Node.js. The kind of build where data integrity and role separation decide whether the product is usable.
▸ Stablecoin Purchasing Platform
Fintech purchasing flow with wallet handling and transaction integrity. A full stack build where being correct under real money is the entire job.
▸ PPE Procurement Portal
Vue.js and Node.js procurement portal with WooCommerce integration, delivered over 242 hours with 5-star feedback. Full stack work that put manual ordering into a system.
▸ SaaS Data Application
Full stack React and Node.js SaaS with role-based dashboards and a data layer built to stay fast as the data grows.
▸ Production Web Applications
Multiple full stack web apps shipped end to end, several earning 5-star Upwork feedback and turning into long-running retainers.
WHO I WORK WITH
Product teams and founders who need one full stack developer to own a React and Node.js build end to end. Companies embedding AI into an existing application. Teams who need a working full stack codebase maintained and extended by a full stack developer who can read it fast. Clients who want long-running ownership, not a contractor who disappears at handoff.
