In 2025, I took a new step. Alongside my continued community work, I began writing an informative blog focused on personal product analysis and first-hand usage reviews. After years of helping families navigate systems from school enrollment to public services I realized how often people, especially parents, are left overwhelmed when trying to choose what’s right for their homes, health, and children. I wanted to bridge that gap.
