Your LLM app works great in the demo. Then real users show up: 12-second responses, a GPU bill that doubled overnight. That gap between "it works" and "it works at 2 AM under load" is the only thing I sell. You're hiring two backgrounds in one person. Five-plus years of DevOps — AWS, GCP, Kubernetes, Terraform — and hands-on Python development: FastAPI backends, RAG pipelines, AI agents. Most freelancers can either build your AI app or keep it alive in production. I'm both, so nothing breaks at the handoff. The work: FastAPI services with streaming and auth. RAG systems where the vector database (Qdrant, Pinecone, pgvector) is actually indexed right. MCP servers — I've built them since the protocol was new. LLM deployment via vLLM, Ollama, or APIs (OpenAI, Gemini, Claude), with batching and caching so you're not paying for tokens twice. Agents with queues, retries, and cost caps, running on infrastructure that scales down when idle — because idle GPUs are how startups quietly bleed. One rule I never break: nothing ships without per-request cost tracking. I've watched "$40 a day" become a four-figure weekend. Send me your stack and where it hurts—or what you want built. I'll reply with the first thing I'd do. Decide about hiring me after that.
