Freelancer Overview

As a Frontend Engineer with 7 years of experience in AI-driven products, I bring a unique technical perspective to AI training and data labeling. I have hands-on experience developing eKYC/identity verification systems with liveness detection at Authme, and building intelligent customer service systems integrated with Microsoft Luis for natural language understanding. My work involved understanding how AI models process and interpret data, which gives me valuable insight into creating high-quality training datasets. My technical background in software development, combined with QA experience in automated testing frameworks, has equipped me with strong attention to detail, pattern recognition, and quality assurance skills. I am proficient in analyzing complex data structures, identifying edge cases, and maintaining consistency—all critical skills for effective data labeling. My experience spans healthcare, security, and financial technology sectors, allowing me to understand domain-specific requirements and contribute meaningfully to AI training projects across various industries.
