Freelancer Overview

I am an analytical and detail-oriented data professional with over three years of experience specializing in data labeling, annotation, and quality assurance, particularly within finance and accounting domains. My background includes categorizing, validating, and auditing large, complex datasets with 100% accuracy, making me adept at providing high-quality training data for AI models in finance, mathematics, and logical reasoning. I am proficient with advanced Excel, QuickBooks, Sage, Odoo, SAP, and Google Data Science Suite, and have streamlined data processes to improve efficiency and accuracy. With hands-on experience in entity recognition, sentiment analysis, and data validation, I excel at identifying patterns and anomalies and ensuring data integrity. My commitment to precision and my ability to work independently in remote environments equip me to deliver reliable, gold-standard data annotations for AI training projects.

Served as a Subject Matter Expert (SME) in Finance and Mathematics to train and fine-tune Large Language Models. My role involved generating high-quality prompts and evaluating AI-generated responses based on strict "Helpfulness, Honesty, and Harmlessness" (HHH) guidelines. I specialized in "Chain-of-Thought" (CoT) reasoning, where I broke down complex financial problems (such as tax calculations or ledger reconciliations) into logical, step-by-step instructions to improve the model's mathematical accuracy and reduce hallucinations.

Contributed high-quality voice recordings for training and evaluating speech/LLM systems. Followed detailed scripts and prompts in various languages including English, German, and French, capturing multiple tasks with varied tone, pace, and emphasis. I ensured clean audio(quiet environment, consistent mic distance, minimal background noise), adhered to file-naming and metadata standards, and flagged pronunciation or quality issues per guidelines.
