What I'm looking for

I’m looking to be a change agent in a challenging, motivating environment—using my data annotation and analysis skills to support organizational growth, while collaborating to improve accuracy, quality, and results.

I’m a Data Annotator who works to “accurately label and categorize data sets” to enhance machine learning model performance. I analyze and process data to ensure high-quality training sets for AI applications, and I collaborate with the data science team to refine annotation guidelines and improve accuracy.

Alongside data work, I’ve built my people-focused foundation as a teacher and information technology educator. I plan and deliver engaging lessons, assess student performance, and foster a positive and inclusive classroom environment, while also helping others build practical Microsoft Office skills. With a consistent track record across education, sales, and IT support, I aim to be a change agent in a challenging and motivating environment that values growth, vision, and results.
