You will get a Custom AI Web App
Project details
I build custom AI-powered web applications that solve real business problems — not templates or no-code prototypes.
Your app will be built from scratch with clean code, modern design, and reliable AI integration. Whether you need a SaaS platform, internal tool, or customer-facing product, I deliver production-ready applications that work on day one.
What I build:
• AI-powered SaaS platforms
• Document analysis and Q&A tools (RAG)
• AI content generators and writing assistants
• Data dashboards with AI-powered insights
• Internal business tools with AI automation
• Customer-facing apps with ChatGPT/Claude integration
Tech stack: Next.js 15, React, TypeScript, Python, FastAPI, PostgreSQL, Supabase, OpenAI/Claude/DeepSeek API, Tailwind CSS.
What sets me apart: I've built and deployed automated systems processing real-time data from multiple APIs, running 24/7 on production servers. I don't just make things work — I make them reliable, fast, and maintainable.
Every delivery includes full source code, documentation, and deployment to your domain.

About Kelvin
AI Integration & Full-Stack Developer | Chatbots, RAG Systems, API
Manchester, United Kingdom - 9:34 pm local time
What I deliver:
→ AI chatbots & virtual assistants (Next.js + OpenAI/Claude/DeepSeek API)
→ RAG document Q&A systems with vector search & source citations
→ AI agent development & multi-step workflow automation
→ AI integration into existing SaaS platforms & legacy systems
→ Automated data pipelines & real-time processing systems
→ API integrations connecting multiple services (CRM, Slack, email, databases)
→ Full-stack web applications with AI features built in
→ n8n / Zapier / Make automation workflows with AI
My background is in building real-time systems that handle live data. I've independently designed and deployed automated bots that process market data from multiple API sources (REST + WebSocket), execute decisions based on custom logic, and run 24/7 on VPS infrastructure. This means I understand production reliability — not just getting code to work, but keeping it running.
Tech stack: Next.js, React, TypeScript, Node.js, Python, FastAPI, LangChain, PostgreSQL, Supabase, Pinecone, OpenAI API, Claude API, DeepSeek API, Vercel AI SDK, WebSocket, Docker, Linux/VPS deployment.
I respond fast, deliver faster, and write clean code with documentation.
