About this gig

I fine-tune open models on your data so they actually understand your terminology, your documents, and your use case.


What I do

  • Fine-tune open-weights LLMs with LoRA or full fine-tuning, on PyTorch and HuggingFace
  • Clean and structure your raw data into a usable training set usually the hardest part
  • Build an evaluation harness so quality is measured, not guessed
  • Export for production: ONNX, TorchScript, or a deployed inference API
  • Run it on your infrastructure, so there are no per-token API costs


Recent work: fine-tuned a model on a client's internal documentation. Accuracy on their benchmark went from roughly 60% to over 90%, running on their own hardware.


How I work

I build the eval set before training anything. Without it there's no way to tell whether a run improved things or made them worse, and most fine-tuning projects skip this step.

I'll also tell you when fine-tuning isn't the answer sometimes RAG or better prompting gets you there for far less.

Message me with your use case and dataset size, and I'll tell you what's realistic.

I build AI systems that make it to production — not demos that break under real traffic. My work is AI agents, LLM integrations, and the backend underneath: pipelines, APIs, and services in Python, Go, and Rust. I also ship smart contracts and dApps on EVM chains, and increasingly projects where AI and on-chain systems meet. Before freelancing: 3 years as a senior backend engineer at pCloud. IBM AI Developer certified. Have something half-built that needs to be production-grade? Send me the details and I'll tell you honestly if I'm the right fit.

    I recently hired bojan for a Bitcoin ordinal task on Fiverr, and I must say I'm extremely satisfied with the service provided. He demonstrated a deep understanding of Bitcoin technology and was able to efficiently complete the task within the specified timeframe. What impressed me the most was his attention...
