About this gig
Need ChatGPT, DeepSeek, Qwen or a local Ollama model inside your product, and need it to work reliably, not just as a demo?
I recently shipped a production LLM integration in my own app, LinguaFlow (C++ core, macOS + iOS + Android): any OpenAI-compatible endpoint, streaming, truncation detection, reasoning-block stripping, timeouts, retries, caching and automatic fallback between engines. I bring the same engineering to your website, backend or mobile app.
What you get:
- Provider wiring (OpenAI, DeepSeek, Qwen, Ollama or any OpenAI-compatible API) with keys kept server-side
- Prompt design plus terminology and style control so answers stay on-brand
- Streaming responses, retries, timeouts and clear error states
- Optional multi-provider fallback and usage/cost tracking
- Tests and a short handover document
Stacks: Node.js, Python, C++, Flutter/Dart, plain REST. I speak English and Chinese and reply within a few hours.
Please message me before ordering with your stack and a one-line description of the feature, so I can confirm the package and delivery time.

Flutter + C++ developer shipping cross-platform apps with a shared native core. My own product LinguaFlow (macOS, iOS, Android) routes translation through Google, DeepL and OpenAI-compatible LLMs with glossary control and automatic fallback, backed by 2,300+ automated tests. I add AI and translation features to existing products, build Flutter apps and fix the native layer (FFI, share extensions, store builds). English + Chinese, fixed quotes, every delivery comes with tests and a handover doc.
FAQ
Which AI providers can you integrate?
Any OpenAI-compatible API: OpenAI/ChatGPT, DeepSeek, Qwen, Moonshot, Groq, OpenRouter, plus local models through Ollama or LM Studio. Anthropic Claude and Google Gemini through their own SDKs on request.
Do I need my own API key?
Yes. You create the account and key with the provider and keep control of billing; I never store it. For a local Ollama model no key is needed at all.
Which stacks do you work with?
Node.js/TypeScript, Python, C++, Flutter/Dart and plain REST for anything else. Frontend: React, Vue or plain HTML. I am happy to work inside your existing repository.
Do you provide the source code?
Always. You get the full source, the tests and a short document describing configuration and how to switch providers or models later.
