Lizaveta Lesina

I’m an analytical, detail-oriented Content and Data Operations Specialist with over 2.5 years of experience in product IT environments. I structure, validate, and moderate large-scale datasets to protect data integrity and keep downstream systems reliable.

In my Content Manager / Data Processing work, I analyzed, verified, and structured high-volume datasets for an internal mobile application database. I moderated digital content, researched authoritative sources for accuracy, and maintained internal CRM and CMS systems—auditing data, correcting formatting, and updating product information.

My impact has been measurable: I processed 60,000+ unique records, localizing and translating them into English while maintaining zero critical errors. I also sustained high-velocity throughput (up to 20 complex requests per hour) under strict quality controls and minimized database error rates to an absolute critical minimum.

I also bring hands-on annotation expertise for ML and computer vision projects, using CVAT to label and classify visual data exactly per guidelines. I’ve annotated around 10,000 images and improved dataset preparation turnarounds by optimizing my CVAT workflow and shortcuts.
