About this gig
Want to add AI to your product, or launch a complete AI SaaS? I build production-ready AI web apps with the OpenAI API, React or Next.js, Node.js and PostgreSQL, from one feature to a full MVP.
What I can build:
- AI chatbots and assistants trained on your own documents (RAG)
- AI writing, summarising and note-taking features
- Voice AI with speech-to-text and text-to-speech
- Full SaaS: login, roles, Stripe billing, admin dashboard
- Deployment on AWS with secure API key handling
Proof:
- AI consultation notes for a clinic platform (Deepgram + OpenAI)
- Real-time Urdu voice assistant and an Alexa voice agent on AWS Bedrock
- A banking support bot on GPT-4o and an AI interior design app
- 4+ years as a Node.js engineer, AWS Certified Developer
How it works:
- Message me with your idea or your existing app
- I suggest the right AI approach, cost and timeline
- I build, test and deploy, with full source code
Not sure what's possible? Message me before ordering and I'll reply with a clear plan.
