Project details
I've integrated LLM APIs (OpenAI, Anthropic Claude) into production products serving 800K+ users (Dende AI), across EdTech and Analytics platforms. I write prompts that return reliable structured outputs, handle streaming responses for fast UX, build RAG pipelines and vector retrieval, and design backend AI workflows that hold up under real traffic - rate limits, retries, token costs. I don't just call the API: I design the full flow from input → prompt → structured output → UI.
