About this gig

Need real, production-ready AI built, deployed, and proven to work? I handle the full lifecycle.

I'm an AI engineer who builds custom LLM systems for a US robotics company: real-time voice assistants, self-hosted models running on private servers, and the benchmarking tools that prove which setup performs best. I can do the same for you, end to end.

What I build for you:

  • Voice agents & AI assistants full speech-to-text LLM text-to-speech pipelines, wake-word, low latency
  • LLM chatbots & AI agents GPT-4o / Gemini, custom knowledge (RAG), tool use, integrated into your app or site
  • Local / open-source LLMs run Llama, Mistral and others privately on your own hardware (Ollama / vLLM), set up and optimized, with no per-token API fees
  • Server deployment GPU servers, Docker, REST APIs; scalable, secure, and offline-capable
  • AI model testing & benchmarking compare models and providers on accuracy, latency and cost under real-world conditions, with clear reports to guide your decisions.

Why me: I've shipped real conversational AI to production, built multi-provider model-benchmarking platforms, and deployed self-hosted LLMs on servers. You get clean, documented, working systems.
