Biotechnology researcher transitioning into AI data annotation and QA.
What I'm looking for
I am a biotechnology researcher with a PhD (in progress) from the University of Minho, combining experimental design, molecular techniques and statistical analysis with hands-on experience in AI data annotation and quality assurance. I have led experimental optimization of an ultrasound prototype and contributed to multiple peer-reviewed publications on seed germination and bioactive extracts.
As an AI data trainer and annotator, I have worked freelance on supervised fine-tuning, chain-of-thought review, prompt design, simulated annotation for multi-step reasoning, and reinforcement learning from human feedback. I bring cross-disciplinary rigor from my lab work—qPCR, microscopy, hydration kinetics and PCA—into precise, reliable annotation and QA processes.
I am motivated to grow in the tech industry, eager to apply my analytical, programming and domain expertise to roles that value accuracy, continuous learning and collaboration in dynamic, innovative teams.
