Freelancer Overview

As a Senior Backend Engineer with 7 years of development experience, I have spent the past 2 years deeply engaged in specialized AI training, code annotation, and quality evaluation. My expertise covers precise Code Alignment, Reinforcement Learning from Human Feedback (RLHF), and establishing gold-standard Supervised Fine-Tuning (SFT) datasets across multiple programming languages, including Java, Python, and Go. Beyond standard data labeling, I have extensive experience in Adversarial Prompt Engineering (Red Teaming). I regularly design complex logical puzzles and sophisticated edge-case coding prompts to deliberately pressure-test large language models, successfully identifying reasoning flaws, hallucinations, and syntax vulnerabilities. Combined with my background in deploying LLM/Agent applications, I excel at adhering strictly to complex guidelines to deliver high-quality datasets for advanced AI model alignment.
