Freelancer Overview

I’ve spent a significant portion of my career focused on the fundamental building blocks of AI: high-quality data. My experience isn't just about clicking boxes; it’s about understanding the nuances of how a model interprets information. I specialize in complex image annotation and NLP entity extraction, where I've learned that a "good enough" label is usually the enemy of a high-performing model. By developing a rigorous personal workflow for edge-case detection, I’ve been able to significantly reduce noise in datasets, ensuring that the training data reflects the messy, unpredictable reality of the real world. What truly sets me apart is my technical curiosity and my background in data manipulation. I’m comfortable using tools like Pandas to audit datasets for bias or inconsistencies before they ever reach the training phase. I don’t just follow guidelines; I help refine them to make the labeling process more intuitive and accurate for the whole team. My goal is always to deliver structured, high-fidelity data that allows developers to focus on architecture rather than troubleshooting poor-quality inputs.

AI Training for Enterprise Business Logic

Computer Code ProgrammingRLHF
This project involves fine-tuning a Large Language Model (LLM) to assist users in navigating complex enterprise resource planning (ERP) systems. My role focuses on RLHF (Reinforcement Learning from Human Feedback) and SFT (Supervised Fine-Tuning) to ensure the model provides accurate, compliant, and logically sound responses to functional business queries. I evaluate model-generated responses based on their technical accuracy regarding accounting principles, inventory valuation methods (such as FIFO and AVCO), and cross-functional workflow dependencies. By ranking multiple model outputs, I help the model learn to prioritize the most efficient and standard-compliant solutions for the end-user.

Fine-Grained Segmentation for Agri-Tech Autonomous Robotics

ImageSegmentation
This project involved the creation of high-fidelity training data for a computer vision model powering autonomous weeding robots. The objective was to achieve pixel-perfect accuracy to enable the robot to distinguish between crop plants and varying types of weeds in real-time. I performed comprehensive semantic segmentation, manually masking every relevant pixel in complex, high-resolution field images. A significant challenge was the occlusion of objects (plants overlapping); I developed specific workflows to accurately define instances of individual crops within dense clusters, directly improving the model’s object detection and pathfinding capabilities.
