Freelancer Overview

As a QA Engineer and Automation Specialist with over 3 years of experience, I bring a rigorous, methodology-driven approach to AI training and data labeling. My background in manual testing and no-code workflow optimization allows me to provide high-fidelity feedback and structured annotations for complex SaaS and Web3 ecosystems. I specialize in identifying edge cases and ensuring data integrity across various digital platforms. I have a proven track record of managing end-to-end quality processes, from initial research to final execution. By combining technical analytical skills with an eye for user experience, I set myself apart as a contributor who understands the 'why' behind the data, ensuring that training models are built on accurate, context-aware information.

Labeling Experience

LLM-Driven Workflow Automation & Integration

TextTextFunction CallingFunction Calling

Developed and validated structured data exchanges between LLMs (Gemini) and third-party APIs via Make.com. My role involved defining function schemas, ensuring the AI correctly mapped JSON outputs to external database fields, and troubleshooting logic failures in automated bug reporting scenarios. I focused on ensuring the model consistently triggered the correct 'tools' based on specific user input triggers.

UX-Centric Model Alignment & RLHF

TextTextRLHFRLHF

Participated in Reinforcement Learning from Human Feedback (RLHF) sessions to align AI model responses with user intent and product usability standards. I ranked and provided qualitative reasoning for model outputs based on clarity, tone, and technical correctness. My focus was on ensuring the AI provided helpful, non-redundant, and logically sound advice for business users.

Technical Documentation Audit & API Validation

TextTextTranscriptionTranscription

Audited and labeled technical documentation and code snippets for accuracy and execution logic. Drawing on my background with Postman and API testing, I categorized code-based responses to ensure they followed standard syntax and functional requirements. I specialized in identifying 'hallucinations' in technical explanations provided by AI models regarding software workflows.

2023 - Present

Scalable Image Annotation for Decentralized AI (Sapien)

ImageImageData CollectionData Collection

Participated in a large-scale image annotation initiative for Sapien, a decentralized AI data layer. The project involved high-precision labeling and tagging of visual datasets to train computer vision models. I maintained a high accuracy rate while navigating the project’s specific Web3-integrated dashboard, ensuring that all metadata and annotations met the platform’s quality benchmarks for decentralized data labeling.
