About this gig
Is your Web or Mobile App falling behind?
You don't need a rebuild to get modern features. I specialize in injecting OpenAI and LangChain directly into your existing architecture. I build secure AI microservices that connect seamlessly to your current backend and UI, whether it's a web dashboard or a native mobile app.
What I can build for you:
- Context-Aware Chatbots: Assistants that know your specific business data (RAG).
- Smart Automation: Auto-generate emails, summaries, or reports within your app.
- Semantic Search: Upgrade search bars to understand intent, not just keywords.
- Data Extraction: Convert unstructured text into structured JSON for your database.
Tech Stack for Integration:
- Models: OpenAI API (GPT-4o) & Anthropic.
- Logic: LangChain for state management & memory.
- Backend: Node.js or Python endpoints bridging your API (REST/GraphQL).
- Data: Vector Databases (Pinecone/Supabase) to index your app's content.
- Frontend: React, Vue, or Mobile (React Native/Flutter) integration.
I bridge the gap between legacy code and modern AI without disrupting your operations.

FAQ
My website is built on WordPress/Wix/Shopify. Can you help?
This gig is primarily for custom-coded websites (React, Node.js, HTML/JS). If you use a platform like WordPress, please message me first, as the process is different.
Do I need an OpenAI API key?
Yes, you will need your own API key from OpenAI. This ensures you have full control over usage and billing.
Is my API key secure?
Yes. I will set up the integration so that your API key remains on the backend (Node.js), ensuring it is never exposed to public users on the frontend.
What is LangChain?
LangChain is a framework that helps the AI "remember" previous parts of a conversation or connect to your specific data. It makes the AI much smarter than a simple text generator.
