Freelancer Overview

I have over five years of professional experience managing complex workflows, research, and high-quality data execution. My background includes a Bachelor of Science (BSc) in Molecular Biology, where I gained hands-on experience with data labeling in microbiology and biotechnology experiments. This scientific foundation is complemented by technical certifications in Data Analytics, Cloud Computing, and Power BI, along with advanced current training in Microsoft Azure, enabling me to handle sophisticated data structures with technical precision. I have a proven track record of assisting Master’s students with data analysis for their theses (Research Projects). Whether I am labeling biological data or building visualizations, I bring a research-oriented approach that ensures training data is accurate, structured, and ready for high-level AI applications.

Labeling Experience

The project was a PhD in TB (Tuberculosis), where I was given a DNA or RNA sequence and asked to "highlight" specific sections. The main core was Cell Classification, which focused on looking at microscope slides and labeling individual cells as "Healthy" vs. "Infected. The measurements varied based on the biological scale (molecules, cells, or tissues).
