Experience
Annotation Quality Analyst - TELUS Digital
(2025-08)
- Orchestrate daily annotation workflows for a team of 10+ annotators across concurrent LiDAR and camera-based AV labeling projects, ensuring on-time delivery with 98%+ quality acceptance rate.
- Conduct structured QA audits on 3D cuboid, semantic segmentation, and polygon annotation tasks — identifying systematic error patterns and implementing corrective feedback loops to reduce rework by ~25%.
- Serve as primary liaison between annotation team and client stakeholders, translating complex annotation guidelines into actionable SOPs, resolving ambiguities that previously caused 15% task rejection rates.
- Track team KPIs (throughput, accuracy, SLA adherence) using QA dashboards; proactively escalate risk items and propose workflow optimisations that improved weekly output by 18%.
- Mentor junior annotators through targeted coaching, reducing onboarding ramp-up from 3 weeks to under 10 days for new hires on LiDAR-based annotation tasks.
Junior Annotator - Intelizign Lifecycle Services Pvt. Ltd.
(2024-06 - 2025-08)
- Executed 2D bounding box, object detection, and gesture recognition annotation tasks on proprietary platforms, achieving quality scores above 95% on client QA reviews.
- Operated LiDAR annotation tools including Kognic, Rosetta, and Morning Star to label point cloud data for pedestrian detection, vehicle classification, and road object segmentation.
- Identified and documented 30+ tool bugs and annotation discrepancies, collaborating with the technical team to improve platform stability for downstream ML model training.
- Supported backend project setup, taxonomy configuration, and dataset structuring — reducing project initialisation time by 20% through standardised configuration templates.
- Delivered onboarding and refresher training sessions on tool usage, annotation guidelines, and quality standards, enabling faster team scaling.
Senior Process Associate – QA - R Process Outsourcing Pvt. Ltd.
(2021-11 - 2024-05)
- Led end-to-end QA validation for 15+ ADAS annotation projects, reviewing LiDAR point clouds, sensor fusion data (2D+3D), and sequential imagery across highway, urban, rural, and expressway scenarios.
- Delivered high-precision outputs for 3D cuboids, semantic segmentation, polygon labeling, and traffic sign recognition, consistently maintaining annotation accuracy above 97% against ground truth benchmarks.
- Identified and resolved annotation inconsistencies in sensor fusion datasets — including misaligned LiDAR-camera overlays and incorrect class labeling — preventing downstream model training errors.
- Established and enforced quality standards, conducting weekly calibration reviews that reduced inter-annotator disagreement by 30% over a 6-month period.
- Handled complex sequential and non-sequential annotation tasks involving multi-object tracking and occlusion handling in dense traffic scenarios, supporting model robustness improvements.
- Streamlined QA workflows in collaboration with project leads, reducing average review cycle time by 22% while maintaining full compliance with client SLA and data accuracy requirements.
