I will integrate openai or claude API into your website or app
Nazmun Nahar
About this gig
Want AI features in your app or website without the guesswork? I integrate OpenAI and Claude APIs directly into your existing product, or build a new AI-powered feature from scratch if you're starting fresh.
What I deliver:
OpenAI or Claude API integration into your website, app, or backend
Works with Python, JavaScript, TypeScript, PHP, or Java codebases
Database and multi-endpoint integration on higher tiers
Clean, documented code tested before delivery
Source code handover available (Premium)
Fine-tuning note: most projects get better results faster from proper prompt design and context handling than a full model fine-tune. If your project genuinely needs custom fine-tuning, message me first for a scoped quote it's priced separately based on your data and goals.
I keep all client code and data strictly confidential no exceptions.
Not sure what you need? Message me before ordering and I'll help you figure out the right package.

Hi, I'm Nazmun Nahar — I build practical AI systems for businesses that want their tools to actually do the work, not just talk about it.
I focus on RAG systems that answer questions from your real documents, AI agents that complete multi-step tasks on their own, and workflow automation using LLM APIs like OpenAI and Anthropic. I build with Python, LangChain/LangGraph, and modern automation tools depending on the project.
I communicate clearly, deliver on time, and ask the right questions upfront. Not sure what you need yet? Message me — happy to help you find the right approach.
FAQ
Do I need an existing app or website?
No. I can integrate AI into something you already have, or build a new feature from scratch if you're starting fresh — just let me know your situation when you order.
What about the AI Model Fine-tuning feature?
Most projects get better results faster from prompt design and context handling than a full fine-tune. If yours genuinely needs one, message me first for a scoped quote — pricing depends on your data.
Is my code and data safe? Can you sign an NDA?
I keep all client code and data strictly confidential and won't reuse or share it. I'm happy to put that in writing in our chat. I don't sign formal legal contracts, but confidentiality is a firm commitment either way.
Which languages/frameworks do you work with?
Python, JavaScript, TypeScript, PHP, and Java. Tell me your stack when you order and I'll confirm compatibility before starting.
OpenAI or Claude or other api — which should I use?
Depends on your use case — I can advise once I know what you're building. If you already have a preference, just mention it in your order.
What if I'm not satisfied with the delivery?
Every package includes revisions (see package details), and I'll work with you to get it right. If something's fundamentally off-scope, let's discuss before you leave a review.
Do I need to give you access to my live production site?
Not necessarily — for WordPress/web integrations, a staging site or local copy is safer for both of us. We can discuss the safest setup for your specific case.
