Nathan Sapwell

Senior full-stack engineer and AI/ML researcher. I build LLM, RAG, fine-tuning and agent systems and ship them inside production applications.

Most AI contractors do not ship production software. Most web developers do not do real ML research. I do both.

Based between Australia and Southeast Asia. I work Australian business hours.

Director of DreamFast Solutions Limited, a Hong Kong registered company.

Current focus

  • Abliteration research. Comparative forensics on the HauhauCS, Heretic and Huihui techniques across Qwen models from 2B to 27B. Benchmark, safety and weight analysis, all open. Published at https://abliterlitics.dev.
  • Local inference tooling. Heretic abliteration containers for NVIDIA Blackwell GPUs, GGUF to safetensors conversion, multi-GPU ComfyUI workflows.
  • Production AI. RAG, fine-tuning, evaluation and agents, built into real Laravel and Vue applications.

Open-source

Tens of thousands of model downloads on Hugging Face. Research and tooling repos below.
