Maria I.

I bring hands-on experience in AI data annotation, multimodal evaluation, dataset validation, and quality assurance across image, video, audio, and text data. My key strengths are attention to detail, analytical thinking, consistency, and the ability to identify subtle errors while following detailed guidelines. I work in a structured and dependable way, whether independently or as part of a team, and remain focused when handling repetitive, high-volume tasks. I value accuracy, clear documentation, and continuous learning. I bring a quality-first mindset that helps deliver reliable, consistent, and production-ready data while supporting better AI outcomes.

• Analyst – AI/LLM Evaluation Practice

  INNODATA KNOWLEDGE SERVICES INC. · 2026 — 2026
  Managed multimodal QA review workflows to ensure defective outputs did not enter validated datasets. Evaluated bounding boxes, segmentation outputs, and object localization annotations ahead of dataset integration to mitigate spatial inconsistency risks. Identified patterns of systemic hallucination and annotation inconsistencies during iterative review cycles, which enhanced evaluation stability and minimized rework. Escalated critical evaluation failures and ambiguous annotation cases before dataset finalization to avert error propagation. Contributed to calibration alignment to reduce evaluator variance and enforced a structured rubric across QA processes while maintaining daily task completion under audit thresholds without compromising quality.

• AI Video Annotation & Dataset Quality Review Specialist (Freelance)

  Frodobots AI · 2026 — 2026
  Annotate and label egocentric (first-person) video datasets supporting robotics and embodied AI model training and evaluation. Segment continuous video recordings into task-specific episodes by identifying workflow transitions, task boundaries, and activity changes. Evaluate task usability based on operational objectives, physical manipulation, hand visibility, task completion, and observable outcomes. Apply structured annotation guidelines to distinguish trainable activities from navigation-only sequences, idle behavior, incomplete workflows, poor-quality footage, and staged tasks. Analyze diverse real-world activities across household, retail, industrial, manufacturing, construction, food preparation, and animal care environments while resolving complex annotation edge cases. Perform quality checks to maintain annotation accuracy, consistency, productivity, and compliance with evolving project guidelines, quality benchmarks, and production requirements.
