You will get ChatGPT and OpenAI AI features integrated into your app or website


Project details
You will get real AI features shipped into your app or website - not just a demo. I integrate ChatGPT and OpenAI GPT-4 for chatbots, RAG search over your own data, and workflow automation, with streaming responses, a clean backend API, and production deployment. As a Director at a software studio, I have delivered AI SaaS platforms end to end - including an AI recruitment system with AI candidate scoring, RAG and analytics - plus six live apps on the App Store and Google Play. You get honest scoping, tested code, secure API-key handling, and clear communication. I build these systems myself, so I know exactly where AI features break and how to make them reliable and cost-efficient in production.

What I can do for you:
• Build a mobile or web app from idea to launch (App Store, Google Play, or production web)
• Add AI features (chat, parsing, recommendations) to your product
• Rescue a rejected app or fix store-compliance issues
• Set up monetization - ads, in-app purchases, subscriptions (RevenueCat)
• Lead delivery of a larger, multi-part product with a reliable team
I care about shipping clean, maintainable software on time, communicating clearly, and getting you to a working, store-approved release. Tell me what you're building and I'll recommend the best path.
