Marija J.

Data-focused professional with hands-on experience in extracting, structuring, and validating information from complex sources, including company registries, legal documents, and KYC-related data. I work with large datasets on a daily basis—cleaning, comparing, and validating data across multiple sources, identifying discrepancies, and turning unstructured inputs into clear, usable formats. I’m comfortable working with messy or incomplete data and defining clear logic to make it consistent and reliable. In addition to data analysis, I have strong experience in manual QA, content review, and annotation. I’ve worked on testing workflows, reviewing LLM-generated outputs, labeling data for AI models, and identifying edge cases that impact overall data quality. I pay close attention to detail and follow guidelines carefully, but I’m also quick to spot when something doesn’t make sense. I’ve also supported product and operations teams by improving internal processes, organizing workflows, and building simple tracking systems (often in Google Sheets) to automate repetitive tasks, monitor performance, and flag issues early. Clients and teams usually rely on me when accuracy matters, deadlines are tight, and the work requires both structure and critical thinking—not just execution. I’m reliable, fast, and take full ownership of my work, from understanding the problem to delivering clean, consistent results.
