AbdulRehman
About this gig
You already have a website, web app or SaaS product. Now you want AI inside it: a chatbot that answers customers, content generated on demand, or documents summarised automatically. I integrate AI into your existing product cleanly, without rebuilding it.
What I can add
- OpenAI (ChatGPT / GPT), Claude and Gemini API integration
- AI chatbot or AI assistant for your website or app
- AI features: text generation, summaries, classification, data extraction
- Function calling so the AI can use your own data and APIs
- Streaming responses, chat history and prompt design
- Secure backend: API keys kept server side, rate limits, usage control
- REST API, GraphQL, webhooks, Stripe and third party API integration
Why work with me
I am a full stack developer working with React, Next.js, Node.js and Ruby on Rails, so I connect the AI model to your real frontend, backend and database. You receive tested, documented, production-ready code.
Who it is for
Startups, SaaS founders and businesses that want a working AI feature in their product, not an isolated demo.
Send me your tech stack, the feature you want and any API access you already have. Message me first to confirm the scope.
