Freelancer Overview

I have hands-on experience in AI data training with a focus on STEM domains, math reasoning, and natural language understanding. At Invisible Technologies, I fine-tuned large language models using Reinforcement Learning from Human Feedback (RLHF), Supervised Fine Tuning (SFT), and prompt engineering, which improved accuracy in technical contexts by over 60 percent. My role also involved designing structured workflows to enhance how the system responded to user queries, ensuring both precision and clarity. Beyond direct AI training, I bring a strong background in data analytics and quality assurance from my work as a Network Performance Analyst and Service Systems Engineer. I automated data wrangling and visualisation using Python and SQL, built intuitive dashboards, and led data quality management for large-scale telecom datasets. These experiences gave me a sharp eye for detail, the ability to spot patterns quickly, and the discipline to document and validate data consistently — qualities essential for producing high-quality training datasets and scalable AI systems.
