What I'm looking for

I seek roles combining AI annotation/QA and biotech domain expertise, in collaborative, learning-focused teams where I can apply experimental rigor, statistical skills, and programming to improve model performance and data quality.

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.
