Labeling Experience

Full Feeder Data Audit & Labeling Project | Injection Substation

DocumentClassification
This project entailed collecting, cleaning, annotating, and evaluating structured billing and energy flow data across multiple feeders. I conducted document review, error identification, and database relabeling to improve energy accounting integrity. Classification criteria were used to flag revenue-impacting errors and support annotation consistency. • Labeled and corrected 38 data-level discrepancies through structured document review • Applied classification annotation on customer records and energy flow documentation • Improved mapping datasets via annotated record reconciliation • Conducted multi-stage annotation and peer review of feeder enumeration records

Data Analyst | Metering, Revenue & Data Quality (Energy Sector)

TextEntity Ner Classification
In this role, I led structured data collection, validation, and document annotation workflows for high-voltage energy distribution systems. I applied audit criteria to flag discrepancies, reclassified billing records, and reconciled entity-to-asset mapping datasets using defined labeling procedures. Quality reports and anomaly detection mirrored annotation pipeline QA flows in the energy data domain. • Executed entity recognition and classification on structured customer and meter records • Conducted document-level labeling and correction of billing entries using Adobe Acrobat • Produced rubric-based quality audit reports and executive annotation summaries • Validated cross-referenced field data, enabling inter-annotator agreement and consistency

Feeder Enumeration & Billing Document Correction

DocumentClassification
For this feeder enumeration and billing project, I performed end-to-end data collection, document annotation, and error review on billing system data. Workflows involved multi-stage annotation, systematic record entry, and anomaly detection using defined labeling standards. Peer review and post-correction processes increased revenue traceability and database accuracy. • Annotated billing entries and customer records across four feeders • Identified and flagged 18 record-level anomalies via document-level annotation • Applied document classification standards for revenue impact analysis • Supported structured annotation peer review for improved correction outcomes

Service Teacher (Data & Records Annotation)

TextClassification
During this role, I maintained and annotated structured student records, attendance logs, and progress reports. Classification schemes and consistent documentation standards were enforced for label accuracy. Detailed recordkeeping and evaluation aligned with document labeling and annotation protocols. • Labeled student entries and academic progress indicators • Ensured data consistency through annotation and structured classification • Produced reports based on rubric-driven criteria • Applied detailed review to flagged discrepancies in documentation

Engineering Intern | Operational Data Annotation

TextClassification
As an engineering intern, I was responsible for annotation and quality review of operational substation data logs. I flagged deviations from expected parameters and maintained systematic inspection logs to ensure compliance. Annotation and data quality control processes supported accuracy in structured operational datasets. • Tagged and annotated operational readings for compliance • Labeled inspection and monitoring entries in substation datasets • Applied threshold-based error identification to logs • Ensured consistency in annotation for audit records and compliance reports
