Labeling Experience

AI Automation Researcher & Content Evaluator

TextRLHF

Evaluated LLM responses using deep analytical matrices, scoring for truthfulness, semantic accuracy, tone, and compliance with complex formatting constraints. Documented failure modes, logical inconsistencies, and visual anomalies, translating observations into quality assurance reports for iterative improvements. Conducted structural prompt tests to identify edge-case limitations and map behavioral shifts across trials. • Rated and scrutinized model generations against truthfulness and semantic accuracy criteria • Classified error types using an error taxonomy log and structured QA documentation • Verified prompt compliance and constraint satisfaction for generated outputs • Produced actionable feedback summaries to support fine-tuning and alignment workflows

Visual Communication Specialist & Motion Graphics Artist

ImageClassification

Executed quality control on multi-layer creative assets by identifying geometric, alignment, and color deviations with pixel-level attention. Managed end-to-end independent review cycles using personal review criteria that mirror structured RLHF-style annotation pipelines. Inspected creative briefs and assets to ensure consistency and correctness across iterative delivery stages. • Verified geometric errors, alignment variance, and color deviations precisely • Applied structured review criteria consistent with modern annotation pipelines • Performed multi-tier independent quality checks during content delivery • Audited visual assets against creative brief requirements

Geospatial Analyst (Academic & Field Projects)

Mapping

Performed spatial data annotation by processing, georeferencing, vectorizing, and cleaning raster and vector layers in GIS workflows. Led ground-truthing field validation by recording systematic observations and cross-referencing field measurements with remote-sensing maps to correct anomalies. Synthesized dense technical notes into structured technical reports with exact proofreading for downstream stakeholders. • Georeferenced and cleaned complex spatial vector and raster layers • Vectorized features to produce labeled spatial outputs • Ground-truthed using field mapping and remote-sensing comparison • Converted observational data into structured reporting documentation
