Freelancer Overview

Over the past several months I have worked as a freelance AI trainer through DataAnnotation, focusing on the evaluation of frontier language models in agentic coding contexts. My work involves assessing model outputs across real-world codebases in Python, Java, and C, analysing code correctness, reasoning quality, and architectural decision-making in complex multi-step tasks. Beyond standard evaluation, I specialize in adversarial prompting: systematically designing prompts to stress-test reasoning boundaries, expose failure modes, and surface inconsistencies in code generation and agentic behavior. My background in Computer Engineering provides the technical foundation to evaluate outputs critically rather than superficially: distinguishing genuine reasoning from plausible-sounding hallucinations, identifying edge cases in algorithm design and data structure implementation, and diagnosing failures in agentic workflows including context mismanagement, incorrect tool sequencing, and hallucinated API usage. I approach every evaluation with the goal of producing signal that is actually useful for model improvement, not just completing tasks.
