Sofia Petrusenko
Scientist studying ageing. Engineer building LLM systems.
I work at the intersection of ageing biology and applied AI. Research training in autophagy, proteostasis and longevity across the UK, Portugal, Germany and Ukraine — now building production LLM systems end-to-end: orchestration pipelines, retrieval-based memory, deployment.
