What I'm looking for

I am looking for opportunities that foster collaboration and innovation in AI development.

I am a detail-oriented Computer Science graduate with a strong foundation in full stack development and expertise in data annotation for AI and machine learning applications. I completed rigorous training and internship as a Full Stack Developer with ALX Africa, proficient in languages such as Python, JavaScript, and Java. My experience includes over 2 years of contract work in remote data labeling, where I contributed to high-quality training datasets for computer vision.

Throughout my career, I have performed high-precision image and video annotation for computer vision models, achieving over 99% accuracy for client datasets. I have collaborated with machine learning engineers to refine annotation guidelines, improving workflow efficiency by 20%. My ability to work independently with flexible hours has allowed me to maintain a 95% on-time delivery rate, ensuring that projects are completed to the highest standards.
