Freelancer Overview

I've worked in data collection and quality control for around 5 years, and my experience has helped me develop strong skills in drafting technical documents, operational reports, and process manuals. In logistics, I managed inventory through accurate reporting to optimize workflows; as a warehouse operator, I prepared classification and labeling manuals to ensure organizational standards. I've created and authored quality control and maintenance reports to identify defects in production processes, machinery diagnostics, and preventive/corrective operations. I'm experienced in English-Spanish translation and technical interpretation, having adapted operational manuals for international equipment and industrial systems, ensuring clear communication among multilingual teams. Every week since 2021, I've dedicated part of the day to writing, reading, analyzing, and reviewing academic reports and papers through a peer assessment methodology and under the tutelage of prestigious professors from my university who recognize my achievements by including me in the honor, dean, and president list. I can navigate inside the semantic fields of music, business, finance, engineering, electricity, mechanics, psychology and neuroscience, mathematics, and quality control. I'm interested in working hard, giving everything I have, and deepening my cultural baggage and critical thinking skills through writing, revising, learning, and collaborating.

The quality control stage of a previous project, where I had to perform reviews, comparisons, analysis, synthesis, and feedback addressing the work carried out by data annotators, re-evaluate the tasks assigned to them, and check if the scores and comments were in line with the performance of LLMs, based on guidelines such as instruction compliance, truthfulness, localization, safety, writing, and overall quality.
