Sofia Petrusenko
Scientist studying ageing. Engineer building LLM systems.
Research training in ageing biology across the UK, Portugal, Germany and Ukraine, focused on autophagy, proteostasis and longevity. Now I build across the frontier model stack, from partnerships with model providers down to the infrastructure production AI runs on: multi-model orchestration, cost-aware routing and observability at the inference layer.
