I am a final-year BSc in Computing student at UNISA with a strong foundation in computer science, programming, and system analysis. My academic journey started with a year of Information Technology studies at Richfield College, where I was introduced to database fundamentals, logic, and core IT principles. Currently, I build code using Python, C++, and web tools like JavaScript, HTML, and CSS, alongside completing full-stack training through the FNB App Academy.

Throughout my studies and practical experience, I have developed a strong practical background in working with data and software systems. As an English AI Data Trainer and Annotator at Alignerr, I work directly with language datasets. My daily work involves evaluating, editing, and annotating complex datasets to improve AI language models, applying Reinforcement Learning from Human Feedback (RLHF), and running quality assurance to eliminate contextual errors. This role requires high technical precision, attention to detail, and analytical consistency.

In addition, my experience as an IEC Counting Officer required absolute accuracy in real-time vote verification and record-keeping. Working as a retail associate at Walmart gave me hands-on exposure to inventory coordination and working with IT teams to keep system data accurate for operational workflows. I also build custom websites as a freelance developer and volunteer as a remote tutor helping Grade 7–11 students in Mathematics, Science, and English.

While my coursework and past projects have covered general software development, my primary technical interests lie in data science, data analysis, and SQL. I am drawn to solving real-world problems by querying databases, uncovering patterns in raw datasets, and using Python and structured database queries to support data-backed decision-making. I enjoy taking high-volume, complex information and turning it into clear, actionable insights.

I am looking for opportunities where I can apply my computational skills, data annotation background, and passion for SQL and analytics. I want to join a team where I can continue learning, work with structured database systems, and help build reliable, data-driven solutions.
