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.

Background
2025 – present
Portugal
Founder & Engineer — AI Content Automation
Independent
Designed, built and operate a full-stack platform for automated media production and distribution: LLM-driven generation pipeline, speech synthesis, video assembly, publishing and analytics, orchestrated through asynchronous background workers. Alongside this, plan and optimise paid acquisition campaigns on Google Ads and Meta against defined cost-per-acquisition targets.

Research Intern
MRC PPU, School of Life Sciences
Investigated stress-induced protein phosphorylation in Saccharomyces cerevisiae and its relationship to longevity. Analysed experimental datasets in R and Python; contributed to a manuscript on the implications for ageing mechanisms.

Portugal
Research Intern
NOVA Medical School
Studied proteostasis and molecular mechanisms of ageing relevant to neurodegeneration and retinal disease, working with cellular models from yeast to human cells and brain and retinal organoids.
05/2022 – 09/2022
UK
Research Technician
Institute of Life Sciences
Investigated autophagy signalling and its alteration during ageing, in cancer, neurodegeneration and diabetes, including work on autophagy in immunity and pathogenic infection.
