5,422 submissions. 98.7% approval rate. Zero pending tasks. That's not a pitch, that's a track record. I'm a Data Annotation Specialist with verified, hands-on experience across every major annotation category. Every number below is pulled directly from my platform dashboard no estimates, no rounding up . What I've delivered: ✅ Data Labeling & Bounding Boxes — 4,941 submitted | 4,890 approved | 99% approval ✅ Image Comparison — 234 tasks | 100% approval ✅ Video Annotation — 156 submitted | 100% approval ✅ Transcription — 50 submitted | 100% approval ✅ Text & AI Response Evaluation — Fluency scoring, factual accuracy, response rating ✅ Prompt Writing — Varied, instruction-aligned prompts for AI training datasets ✅ Audio Annotation — Timestamp marking, speaker identification, sound classification Why this matters to you: Most annotation projects don't fail because of bad tools they fail because of inconsistent contractors who need constant supervision, leave tasks half-done, or deliver work that gets rejected in bulk. That's not a risk you take with me. I follow instructions precisely, work independently, and don't stop until the batch is clean. My approval rate across thousands of real submissions isn't a claim it's documented. Advanced English fluency means my notes, justifications, and communication are always clear no back-and-forth over ambiguous labels. Immediately available. 10 hours daily.
