Freelancer Overview

Drawing from my Master of Science in Computer Science from Georgia Tech and over five years of experience in AI-augmented operations, I specialize in the high-level supervision and fine-tuning of Large Language Models (LLMs). My expertise is centered on RLHF (Reinforcement Learning from Human Feedback) and Supervised Fine-Tuning (SFT) , particularly for technical domains such as Python-based autonomous agents and complex API integrations. I have a proven ability to evaluate model-generated code for algorithmic efficiency and security, ensuring that automated systems adhere to strict operational standards while maintaining high-quality outputs. What sets me apart is the unique intersection of my technical coding proficiency and my deep background in Customer Experience Management. I don't just label data; I architect the logic that powers it, as demonstrated by my project developing an autonomous routing agent using LangChain and the OpenAI API. With an AWS Certified Machine Learning – Specialty certification and a track record of reducing manual inquiries by 63% through automated knowledge base architecture , I provide the domain-specific expertise required to train AI models that are both technically robust and empathetically aligned with user needs.

Leveraging a Master of Science in Computer Science from Georgia Tech , I specialize in the fine-tuning and evaluation of Large Language Models (LLMs) focused on system-level programming and autonomous workflows. My expertise includes: * Code Quality Evaluation: Providing high-fidelity ratings for model-generated Python code, ensuring adherence to PEP 8 standards and optimal algorithmic complexity. * Agentic Logic Training: Developing and annotating datasets for LangChain and OpenAI API integrations to improve model performance in multi-step reasoning and autonomous ticket routing. * API & Microservices: Writing 'ground truth' SFT pairs for RESTful API integrations and microservice architectures to reduce hallucination in technical documentation tasks. * Security & Red Teaming: Evaluating model outputs for security vulnerabilities in cloud environments (AWS/Azure) , specifically focusing on preventing injection attacks in automated support systems.
