You will get Build an AI-powered web MVP with Next.js and OpenAI
Project details
I will turn your AI product idea into a working web MVP with a clean user interface, reliable API integration, and source code you can continue building on.
This service is for founders and teams who need more than a chatbot demo. I build practical AI workflows around real user needs, such as content generation, AI-assisted review, structured forms, image-generation flows, internal tools, or customer-facing AI features.
I have 7+ years of full-stack development experience and focus on AI applications built with Next.js, React, TypeScript, Java/Spring Boot, APIs, databases, and asynchronous workflows.
What you will receive:
• A responsive web application or feature
• An AI workflow powered by OpenAI API
• Clean frontend and backend integration
• Source code and setup documentation
• A short handover walkthrough

About Junner
IT & Networking
Guiyang, China - 4:53 am local time
My strongest area is practical AI application development. I do not just connect an LLM API to a chat box—I design the complete workflow around it: user roles, asset management, prompt flows, async tasks, real-time progress, review loops, structured outputs, content safeguards, and usable admin tools.
Recent independent projects include:
• An AI product-image generation workspace for fashion brands, supporting model, pose, and background assets; image generation; review and iteration workflows; credits; downloads; and real-time task progress.
• A browser-based 3D room-planning and wiring workspace built with Three.js and a structured JSON scene engine.
• An AI-powered homework and assessment platform with question-bank, assignment, and workflow features.
What I can help you build:
• AI MVPs and internal tools
• LLM / OpenAI API integrations and AI workflows
• Next.js, React, TypeScript web applications
• Java / Spring Boot backend services and REST APIs
• Admin dashboards, role-based workflows, and real-time task systems
• E-commerce product-image and content-generation workflows
• Interactive 3D web experiences with Three.js
• Deployment, API integration, debugging, and product iteration
Core stack:
Next.js · React · TypeScript · Java · Spring Boot · Python · REST APIs · OpenAI API · Dify · WebSocket · RabbitMQ · Docker · Linux · Nginx · Three.js
Clients work with me when they need clear communication, realistic scope estimates, regular progress updates, and a developer who can take ownership from requirements through delivery.
If you have an AI product idea, an existing application that needs improvement, or a workflow that should be automated, send me a message with your goal and current setup.
