About this gig

Is your AI app broken, slow, or giving bad answers? I fix and ship LLM apps for a living.


I can help with:

  • Errors in LangChain, LangGraph, LlamaIndex, or the OpenAI and Anthropic SDKs
  • RAG that retrieves the wrong chunks or hallucinates: chunking, embeddings, reranking, and prompts
  • Slow or expensive inference: caching, smaller models, batching
  • Vector databases (Chroma, pgvector, Pinecone, Qdrant)
  • Deploying to Cloudflare Workers, AWS, GCP, Railway, or a VPS with Docker
  • FastAPI or Node backends around your model


How it works:

  • You share the repo (or the relevant files) and the error or behavior
  • I reproduce it, fix it, and explain the root cause
  • You get a clean commit or PR


Message me with your error first and I'll confirm I can fix it before you order.

AI Product Engineer focused on production-grade LLM systems, optimized inference, and scalable agent architectures. I specialize in cost-efficient model deployment, quantized high-performance inference (HQQ/AWQ), RAG systems at scale, and LangGraph agent workflows. I’ve reduced inference costs by 35%, improved operational efficiency by 60% through automation, and deployed AI systems handling 500k+ documents with enterprise-level reliability. I build AI products - not scripts. Let’s design something that scales.
