The Story Behind the Data

I'm a data scientist with a deep commitment to using AI and machine learning for meaningful impact. My journey began with two intensive bootcamps — the ALX Data Science Bootcamp (14 months) and the Applied Data Science Lab at WorldQuant University — where I built a solid foundation across the full data science lifecycle.

I've taken that foundation into the real world, winning two AI hackathons: one for a voice-first assistant for people with visual disabilities using Google Cloud & Africa's Talking APIs, and another building an AI solution for women entrepreneurs in informal markets.

Beyond technical skills, I'm currently studying Applied Artificial Intelligence at IU University deepening my knowledge in advanced AI systems and real-world applications.

I participated in the Africa Trust & Safety LLM Challenge on Zindi, further expanding my applied experience in large language models and responsible AI.I’m passionate about building AI solutions that are practical and capable of driving real-world change.
