Gig Summary
About this gig
Want a ChatGPT-style assistant inside your product? I'll build a polished AI chat into your React / Next.js app that's fast, streams its answers and is ready for production.
At my last job I built LLM-powered features for an enterprise product: real-time streaming responses (SSE), complex chat state, and secure integration with backend systems.
What I can build:
- A chat UI with streaming replies, markdown and code blocks
- Integration with OpenAI, Claude (Anthropic) or Gemini APIs
- A secure backend (Node.js or Python / FastAPI) that keeps your API keys off the client
- Chat history, multiple conversations, stop/regenerate
- Answers based on your own docs or data (RAG)
- Custom prompts, tools and function calling
Message me with what you want the assistant to do and I'll recommend the simplest solution that works.

Hi, I'm Bogdan, a Full Stack Engineer with 9+ years of experience building React apps for enterprise products used by 10,000+ people.
I can help you with:
- React / Next.js / TypeScript frontends
- Node.js / NestJS APIs with PostgreSQL or MongoDB
- AI chat features: streaming responses and LLM integration
- Bug fixes, refactoring and performance work
I write clean, tested code, I communicate clearly, and I deliver on time. Message me before you order and I'll send you a free estimate.
FAQ
Do I need my own OpenAI or Claude API key?
Yes. The API usage is billed to your own account, so you keep full control of costs. I'll help you set it up and add usage limits.
Can you add a chatbot to an app that's already built?
Yes, that's the most common case. I'll add the chat to your existing React or Next.js app so it fits your design and your backend.

Bogdan was super fast and delivered beyond the expectations, he also cleaned some code and was pretty diligent. While we were communicating to bring a deep understand of the task, he also recommended us a faster approach. Really helpful at all times, would love to work again with him soon!
