I will integrate openai, gemini or claude ai into your react or python app
Umar Inayat
About this gig
Need AI in your product, or have an AI feature that "mostly works" and needs to be reliable? I add LLM features to existing React, Next.js, Node.js and Python (Flask, FastAPI) apps.
What I build:
- Summaries, classification, tagging and data extraction from text or documents
- AI grading, feedback and review workflows
- Chat assistants grounded in your own data (RAG)
- Structured JSON output your code can trust, with validation and retries
- Provider fallback (OpenAI, Gemini, Claude, DeepSeek) so one outage doesn't stop your app
- Cost control: caching, rate limits and the right model for each task
How I work: I build a small test set from your real data and measure results, so every prompt change is checked against it. You get clean code in your repo, not a black box.
I've shipped AI features to production for an education platform (grading handwritten answers, essay feedback in English and Chinese).
Message me with what you want the AI to do and your stack, and I'll suggest the simplest approach.

I build AI systems that read messy documents: scanned PDFs, phone photos, tables, handwriting and mixed English/Chinese text. They turn them into clean data (Excel, JSON, database) or into chatbots that cite the exact page each answer came from. Recent work: exam digitization and AI grading for an education platform, AI essay marking, and a healthcare HL7 integration. I test every build on your real files and report the accuracy, so you know what you get. Python, React, Node.js, OpenAI, Gemini, LangChain.

FAQ
Do I need my own API key?
Yes. You keep control of the account and costs; I set up the key handling so it never reaches the browser.
Can you work in my existing codebase?
Yes. I work in your Git repository, follow your code style and keep changes small and reviewable.
Which model should I use?
It depends on the task, speed and budget. I test 2-3 candidates on your data and show you the accuracy and cost of each.
Can you fix an AI feature someone else built?
Yes. I start by measuring how often it fails on real inputs, then fix the biggest causes first.
