Freelancer Overview

I am a Computer Science and Finance dual-degree student at the University of Maryland with a strong background in technical AI training data, RLHF, and code annotation. From February to May 2026, I worked at Handshake AI, where I engineered complex bugs inside code repositories to stress-test and stump advanced AI models. Additionally, from May 2024 to February 2025, I worked as an AI Prompting Engineer Contractor for DataAnnotation, utilizing Reinforcement Learning from Human Feedback (RLHF) to optimize over 5 unique LLMs and auditing 500+ programming prompts to evaluate logic and correct flawed code.

Labeling Experience

Handshake AI Fellow

Computer Code ProgrammingPrompt + Response Writing (SFT)

Engineered adversarial software engineering benchmarks to stress-test LLM capabilities. Located issues within repositories, implemented codebase fixes, and authored robust test suites featuring "Fail-to-Pass" (F2P) test cases to strictly validate the code changes against edge cases. Developed complex, comprehensive problem descriptions designed to stump the model, evaluating its ability to autonomously diagnose repository-level bugs and successfully pass the engineered edge-case tests.

Data Annotation Coding

Computer Code ProgrammingRLHF

Authored complex programming prompts to benchmark and compare code generation quality between competing LLMs. Audited model outputs for logic flaws and bugs, wrote optimized code fixes to correct poor model responses, and provided structured evaluation ratings to researchers for RLHF training.
