Labeling Experience

Freelance API & Logic Validator

Other
As a Freelance API & Logic Validator, I audited and verified the performance and logical coherence of automated scripts in browser automation pipelines. The primary task involved the systematic decomposition of natural language requests into precise programmatic actions, ensuring output accuracy and standards compliance. I identified and corrected data-type mismatches and syntactical errors to maintain data integrity. • Validated logic and code structure for Python automation scripts. • Decomposed natural language into executable steps for automation evaluation. • Ensured syntactic and data-type accuracy in automated outputs. • Maintained rigorous QA processes for browser automation pipelines.

Lead Data Validator & Prompt Engineer (Project DealHunter / ChalkTwin)

TextPrompt Response Writing SFT
As Lead Data Validator & Prompt Engineer, I developed and optimized prompts to train large language models for structured data extraction from e-commerce sources. My role included rigorous enforcement of JSON schemas and ongoing quality control of AI outputs, ensuring high accuracy and reliability. I systematically identified and resolved data quality issues, acting as the final QA step for LLM-generated outputs. • Engineered zero-shot and few-shot prompts for text and code LLMs specifically targeting unstructured DOM data. • Designed strict JSON schema validation processes to prevent AI hallucinations and enforce data compliance. • Conducted high-volume review and correction of malformed outputs. • Acted as process owner for prompt boundary refinement and anomaly handling.
