RLHF

Freelancer Overview

AI Trainer and Data Specialist with a strong engineering background and hands-on experience in RLHF, model evaluation, and prompt engineering. Brings nearly a decade of professional experience in complex workflows, research, and quality-focused execution. Currently pursuing a Master's at Aalto University (Machine Learning/AI minor) , building on a BS in Electrical Engineering. My AI-training focus includes evaluating LLM outputs for technical accuracy, realism, and edge cases across Python, Java, and C/C++ domains.

Labeling Experience

Coder – AI Training

Computer Code ProgrammingRLHF

As a Coder – AI Training at Outlier.ai, I created engineering problems and evaluated LLM outputs for technical accuracy. I assessed edge case handling and the realism of code generated by language models. I delivered actionable feedback to enhance model quality in code generation for multiple programming languages. • Developed coding challenges to test AI problem-solving skills • Evaluated Python, Java, and C/C++ AI-generated code outputs • Provided targeted feedback to address technical and edge-case issues • Rated and reported LLM performance for iterative improvement

Freelance AI Tutor / Software Developer (Python)

MindriftComputer Code ProgrammingRLHF

As a Freelance AI Tutor and Software Developer at Mindrift, I annotated and evaluated AI outputs using RLHF pipelines. I supported generative AI development through Python-based coding tasks and reinforcement learning from human feedback. I also fine-tuned language models and provided structured feedback on model performance. • Annotated AI-generated text and code responses for accuracy and relevance • Provided human feedback to improve reinforcement learning pipelines • Fine-tuned LLMs for domain-specific use cases • Delivered evaluation and feedback reports on AI model outputs
