Summary

Transitioning from a background as an IT Business Analyst to a Junior Machine Learning/AI Engineer. With several years of experience bridging the gap between business needs and technology, I’m now focused on building intelligent, data-driven solutions through machine learning and artificial intelligence.

I'm actively developing my technical skill set through hands-on learning and certifications, including the AWS Machine Learning Engineer certification. I'm gaining proficiency in Python, data science, and key ML frameworks, combining this with my analytical mindset and product understanding.

Open to opportunities as a Junior ML/AI Engineer where I can apply my growing technical expertise and contribute to impactful, real-world AI projects.
