Arun C
About this gig
I integrate ChatGPT and OpenAI APIs into websites and mobile apps properly, with security and cost control built in, not a quick hack that burns your API budget.
With 6 years of development experience, I build AI chatbots, customer support automation, content generation tools, AI writing assistants, and conversational interfaces. I work across React, Vue, Node.js, Python, PHP, Flutter, React Native, and native iOS/Android.
MY PROCESS:
- Requirements analysis your use case, your existing stack
- Implementation secure API key handling, backend endpoints, error handling, rate limiting
- UX polish brand-voice responses, conversation context, loading states
- Testing + deployment with full documentation
WHAT YOU GET:
- Working ChatGPT integration in your app or site
- Complete commented source code
- Secure key management (never exposed client-side)
- Cost-optimized API calls fewer tokens, lower monthly bills
- Admin/config panel so you can tweak without code
- 14 days of free post-delivery support
Delivery in 3 days, expedited options available.
Message me with your platform and use case before ordering I'll tell you exactly how I'd build it.

I build mobile apps that ship — Flutter, Android (Kotlin), iOS (Swift), with the backend included.
5+ years experience. 10+ apps live on Play Store & App Store. Firebase MVPs, Node.js REST APIs, auth flows, Razorpay/Stripe payments, clean MVVM architecture.
Stack: Flutter · Kotlin · Swift · Node.js · Firebase · Supabase · MySQL
Got a Figma file? I'll turn it into a working app — UI, API, data layer, done. No separate backend dev needed.
Tight communication. Realistic timelines. I don't disappear mid-project.
Let's talk scope.
FAQ
What ChatGPT models and APIs do you support?
I integrate all OpenAI models including GPT-4, GPT-4 Turbo, GPT-3.5 Turbo, and the latest ChatGPT API versions. I also work with custom fine-tuned models, function calling, vision API, and embeddings based on your project requirements.
Will the ChatGPT integration work on both iOS and Android apps?
Absolutely! I provide cross-platform ChatGPT API integration for native iOS (Swift), Android (Kotlin/Java), React Native, Flutter, and web applications. All implementations include proper error handling and security protocols.
Do you handle API key security and cost optimization?
Yes, security is paramount. I implement secure backend proxy servers, environment variable protection, rate limiting, token optimization, and cost monitoring. You'll never expose your API keys directly in client-side code.
What if I need custom prompts or specific ChatGPT behaviors?
I specialize in prompt engineering and system message configuration. I'll customize the AI's personality, response format, context retention, and behavior to match your exact use case—whether it's customer support, content generation, or data analysis.
Can you integrate ChatGPT with my existing database or CRM?
Yes! I integrate ChatGPT with databases (Firebase, MySQL, MongoDB), CRMs (Salesforce, HubSpot), vector databases for semantic search, and any REST/GraphQL APIs. Your AI can access and update real-time business data seamlessly.
What happens if OpenAI's API changes or has downtime?
I build production-grade integrations with fallback mechanisms, retry logic, graceful error handling, and status monitoring. I also provide 30 days of free post-delivery support to address any API updates or technical issues.
Do I need to provide my own OpenAI API key?
Yes, you'll need your own OpenAI account and API key for production use. I'll guide you through the setup process, help with billing alerts, and configure usage limits. For testing, I can use development keys before handoff.
