Gabriel Ferreira

I am a detail-oriented professional with experience in data annotation, AI model evaluation, administrative support, and agricultural operations. I have worked closely with large-scale datasets and followed strict annotation protocols to support the training and fine-tuning of Large Language Models.

In annotation and RLHF projects, I evaluated AI-generated responses for accuracy, relevance, coherence, tone, and safety, performed prompt analysis and response ranking, and provided clear feedback to improve model performance. I consistently met productivity and quality benchmarks while collaborating asynchronously with project managers and QA teams.

As an administrative assistant, I completed import and export entries, compiled shipment documentation, and conducted follow-up actions post-clearance. In agricultural roles I inspected and classified crops, monitored pest and batch development, and recorded production activities and costs.

I bring strong analytical skills, proficiency with Microsoft Office, Power BI, Tableau, SQL, and Python, and fluency in multiple languages (Brazilian Portuguese native, Spanish C2, Galician C1, English C1). I seek roles where I can apply AI evaluation experience, quality assurance rigor, and operational support to deliver reliable, ethically aligned model outputs.
