Approach
Why I build
I spent my placement year at Roche building AI tools that actually got used — OCR automation, a fine-tuned LLM, data pipelines that replaced manual processes people had been living with for years.
Now I'm co-founding Stoneset.ai, a compliance tool for the EU AI Act. I run product and operations. We're early and building fast.
