I will build a web app or admin dashboard with react node and java
Zhangzc
About this gig
I build web apps and admin dashboards that work. If you run your business on spreadsheets, email, or tools that do not talk to each other, I can turn it into one clean web application.
What I build:
- Admin dashboards with login, user accounts, and role-based access
- Web apps that connect to your APIs, databases, and existing tools
- Frontend and backend built with React, Node, and Java
Recent work:
- A four-platform customer service system with a Java backend and a web dashboard, used by staff every day
- Business web apps with real user accounts and live data, not static templates
Before I write any code, I ask what you are trying to solve. You get a tool that fits your actual workflow, clear updates while I build, and delivery on the agreed date.
Tell me what you manage manually today. I will tell you what I would build first.

I help businesses automate work with AI.
What I do:
- Build ChatGPT apps and chatbots that answer from your documents (RAG)
- Create Make/Zapier workflows with AI: classification, summaries, emails
- Build web apps and dashboards with React, Node.js, and Java
I've shipped production systems used daily — a medical AI agent, a
four-platform customer service system, and iOS/Android apps.
You get working code, clear docs, and a video of every step. Tell me
one task you do manually each week, and I'll show you how to automate it.
FAQ
Do I need hosting or a domain?
Not to start. I can build the app first and help you pick hosting when it is ready to launch. If you already have hosting, I deploy directly to it.
Can you connect the app to my existing database or API?
Yes. Tell me what systems you use and I will confirm the connection before we start. This is included in the Standard and Premium packages.
What if something breaks after delivery?
Every package includes revisions, and bugs in what I built are fixed for no extra cost. If you want new features later, we add them as a small follow-up order.
